I am thinking of two numbers. The first is 5 more than the second. If you add the first number to three times the second number, you get 29. What are the two numbers?
Answer:
11 and 6 respectively
Step-by-step explanation:
1st number=x
2nd number=x-5
three times the second number=3(x-5)=3x-15
3x-15+x=29
put the liketerms together=3x+x=29+15
4x=44
(divide both sides by 4)x=11
Sally's basic cable plan costs $55 a month and an additional $3 for each premium channel.
Cable plan B costs $60 and an additional $2.50 for each premium channel. Which plan is
cheaper if Sally wants to order 10 premium channels?
Step-by-step explanation:
Sally is paying $55 + $3×10 = $85 currently
if she switches to plan B the she will pay $60 + $2.50×10 = $85
That shows both of the cable plan costs same for monthly payment + 10 premium channels

Answer:
3n + 6
Step-by-step explanation:
So the simplified version is 3n + 18
3n + 6 X
3n + 18 = 3n + 18
2n + 8 + n + 10 = 3n + 18

How much will it cost in Canadian dollars to purchase €2000 at a bank that charges a 2.2% commission on the transaction? Use an exchange rate of $1 Canadian equals €0.711142.
Answer:
$2,874.25 Canadian dollar
Step-by-step explanation:
The first thing to do here is to calculate the amount of the commission.
That would be 2.2% of €2,000
= 2.2/100 * €2,000 = €44
Now the total cost to pay = selling price + amount in commissions = €2,000 + €44 = €2,044
But we need our answer in the Canadian dollars
Mathematically;
$1 Canadian = €0.711142
$x Canadian = €2,044
x = (2,044 * 1)/0.711142
x = 2,874.25014975912
This is approximately $2,874.25 Canadian dollar
Leo wants to paint a mural that covers a wall with an area of 300 square feet. The height of the wall is 13 of its length. What is the length and the height of the wall?
Answer:
l=30ft
h=10ft
Step-by-step explanation:
Area 'A' is defined as the product of length and height
[tex]A=lh=300ft^2\\h= \frac{1}{3} l[/tex]
[tex]\\300=l( \frac{1}{3}l)\\300=\frac{1}{3} l^{2}\\900=l^{2}\\30=l\\l=30ft\\\\h= \frac{1}{3}(30)\\h=10ft[/tex]
Thus, the length and the height of the wall is 30 ft and 10 ft respectively.

Ramiro is also a college student. He has a credit card balance of $500.00. The APR on his card is 18.24%. His minimum payment is $10.00. (do not use commas or dollar signs in the answers)
How much will he pay in all?
Answer:
No of Monthly payments it would take to pay off his credit card = $94.601 per month
Step-by-step explanation:
If Ramiro made monthly payments at the end of each month, how long would it take to pay off his credit card?
No of Monthly payment it would take to pay off his credit card = nper(rate,pmt,pv,fv)
No of Monthly payment it would take to pay off his credit card = nper(18.24%/12,10,-500,0)
No of Monthly payment it would take to pay off his credit card = $94.601 per month.
Why does (-4 1/2)^2 = 20.25? Thank you please hurry!
Answer:
See below.
Step-by-step explanation:
Squaring a number means to multiply the number by itself.
For example, 3^2 means 3 * 3.
8^2 means 8 * 8.
(-6)^2 means (-6) * (-6).
In each case above, you see that the number that is squared is multiplied by itself.
In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5
(-4.5)^2 = (-4.5) * (-4.5)
Now we need to actually multiply -4.5 by -4.5
When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5
4.5 * 4.5 = 20.25
Therefore, (-4.5)^2 = 20.25
Seth sold 20% of his baseball cards during week one. During week two, he bought 20% more cards than he had after week one. If he now has 10 fewer cards, how many cards did he have originally? (he had more than 100 cards originally.)
Answer:
250 cards
Step-by-step explanation:
Let the number of baseball cards he originally had be x.
He sold 20% of the baseball cards after week one. This means that after week one the number of cards he had was:
x - (20/100 * x) = x - 0.2x = 0.8x
During week two he bought 20% more cards than he had after week one. This means that after week two, he had:
0.8x + (20/100 * 0.8x)
= 0.8x + (0.2 * 0.8x)
= 0.8x + 0.16x = 0.96x
He now has 10 fewer cards. This means that:
x - 10 = 0.96x
Collecting like terms:
x - 0.96x = 10
0.04x = 10
=> x = 10/0.04 = 250
He had 250 cards originally.

Answer:
c= 3/5(n)+2.5
Step-by-step explanation:
Let
c -----> the cost of some taxi journeys
n ----> the number of miles
we know that
The graph is a line
The equation of a line in slope - intercept form is
c=m(n)+b
where
m is the slope
b is the c-intercept (value of c when the value of n is equal to zero)
Observing the graph we have the points
(0,2.5), (5,5.5)
Find the slope
The formula to calculate the slope between two points is equal to
m= c2-c1/n2-n1
substitute the values
m=5.5-2.5/5-0
m=3/5
we have
b=2.5 -----> because the point (0,2.5) is the c-intercept
substitute in the equation of slope-intercept form
c=3/5(n)+2.5
I hope that gives you your answer please mark me brainliest :)

Using the properties of a kite, what is the measure of Angle X? 70° 90° 130° 140°
Answer:
70°
Step-by-step explanation:
Properties of a kite are:
a) They have two congruent sides
b) Their diagonal is perpendicular to each other.
c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same
We would be using the property of a kite that says "On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same" to solved this question.
In the diagram , the angles Z and X are opposite and congruent to one another. This means they are equal to each other.
Since angles Z= angle X
Let us call both of them angle a
Since a Kite is a Quadrilateral shape, the sum of angles in a Quadrilateral = 180°
Angle W = 90°
Angle Y = 130°
Angle X = a°
Angle Z = a°
Hence,
90° + 130° + a° + a° = 360°
220° + 2a° = 360°
2a° = 360° - 220°
2a° = 140°
a° = 140/2
a° = 70°
Therefore, from the calculation above, we can say that the measure of x = 70°
Answer:
70°
Step-by-step explanation:
Properties of a kite are:
a) They have two congruent sides
b) Their diagonal is perpendicular to each other.
c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same

what is the transitive property
Answer:
the transitive property of uniformity reveals to us that on the off chance that we have two things that are equivalent to one another and the subsequent thing is equivalent to a third thing, at that point the primary thing is additionally equivalent to the third thing. The recipe for this property is in the event that a = b and b = c, at that point a = c.

in a survey of students 60% were in high school in 40% were in middle school of the high school students 30% had visited a foreign country if a survey of student is selected at random what is the probability that the student is in high school and has visited a foreign country?
Answer:
0.18
Step-by-step explanation:
Given: 60% students were in high school, 40% were in middle school and of the high school students, 30% had visited a foreign country
To find: probability that the student is in high school and has visited a foreign country
Solution:
Let x denotes total number of students
Number of students in high school = 60% of x = [tex]\frac{60}{100}x[/tex]
Number of students in middle school = 40% of x = [tex]\frac{40}{100}x[/tex]
Number of students who are in high school and have visited foreign country = 30% of Number of students in high school = [tex]\frac{30}{100}(\frac{60}{100})x=\frac{18}{100}x[/tex]
Probability that the student is in high school and has visited a foreign country = Number of students who are in high school and have visited foreign country/ Total number of students = [tex]\frac{\frac{18}{100}x}{x}=\frac{18}{100}=0.18[/tex]

The perimeter of the rectangle is 20 cm. One side is 6 cm long. What is the length of the missing side
Answer:
it is 4cm long
Step-by-step explanation:
You multiply 6 by 2 to get 12, then subtract 12 from 20 and get 8. Then you divide 8 by 2 to get 4. If you want to check it, you can add 6+6+4+4 to get 20
Answer: 4
Step-by-step explanation: the definition of a rectangle states that opposite sides of the rectangle are congruent. this means that there is 2 sides that measure 6cm. These two sides added together give us 12cm. By working backwards, we can subtract 12cm from the perimeter (20cm), this gives us 8cm. by diving that by 2 we can find the lenght of the missing sides, 4cm each.
find the axis of symmetry for this parabola y=-2x^2-4x-11
write your answer as an equation
Answer:
x = - 1
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
y = - 2x² - 4x - 11 ← is in standard form
with a = - 2 and b = - 4 , thus
x = - [tex]\frac{-4}{-4}[/tex] = - 1
x = - 1 is the equation of the axis of symmetry
