Answer:
10 pencils
Step-by-step explanation:
Given that:
Number of pencils bought by Sam and Sara are the same.
Let the number of pencils bought = x
Sam put 1/4 in his pencil box
Sara put 1/2 in her pencil box
1/4 of Sam's pencil = 5
That is ;
1/4 of x = 5
x /4 = 5
x = 20
Hence, number of pencils Sara put in her box
:
1/2 of 20
1/2 * 20
20/2
= 10
10 pencils

1. x+20 = 11x + 30
x=
Answer:
Step-by-step explanation:
x+20=11x+30 minus x from both sides
20=10x+30 minus 30 from both sides
-10=10x divide by 10
x= -1
Answer:
-1

There are 4 consecutive even integers with a sum of 324. What is the least of the 4 integers?
Answer:
let the 4 consecutive even number be x, x+2,x+4,x+6
now
x+x+2+x+4+x+6=324
or 4x+12=324
or 4x=314
x=78
least integer=78

Eve and Maria have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Eve earns a base wage of $14 per hour, as well as $1 for every subscription that she sells. Maria gets $2 per subscription sold, in addition to a base wage of $3 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How much would each one earn? How many subscriptions would that be?
Answer:
if Maria sells 6 she will make 12 add base wage she earned 15. if eve sells 1 she will also make a profit of 15

What is the equation of the line that passes through the point (-5,3) and has a slope of -6/5 ?
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1 = -5 and y_1 =3 and m= -6/5
the equation : y - 3 = -6/5(x +5)
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1 = -5 and y_1 =3 and m= -6/5
the equation : y - 3 = -6/5(x +5)

A TV that usually sells for $192.15 is on sale for 20% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
Answer:
$162.94
Step-by-step explanation:
Because 20% off of 192.15 = $162.94 and
$153.72 + (6.0%) $9.22 = $162.94
30° + 180° (2n + 1), its radian measure is equivalent to?
Answer:
Example: Find the radian measure of the angles −70° and 120°.
Solution: To find the radian measure of −70° we multiply −70 by the conversion factor /180. We get
Similarly, for 120° we obtain
Note that when we write an angle as a fractional amount of , for example 2/3 times we write the result either as the numerator times divided by the denominator or as the fraction times . So the two values
are equivalent ways of writing the same number. You will see both methods used in the text and in the exercises.
Example: Find the degree measure of /12.
Solution: The conversion factor for going from radians to degrees is 180/. We get
and so the radian measure of /12 is 15°.

Find sin A and cos A
A) sin A = 3/5; cos A = 4/5
B) sin A = 4/5; cos A = 3/5
C) sin A = 5/4; cos A = 4/5
D) sin A = 4/3; cos A = 3/4
Answer:
B
Step-by-step explanation:
sinA=opp/hyp
sinA=16/20=4/5
cosA=adj/hyp
cosA=12/20=3/5
Answer:
We found sinA= 3/5 and cosA=4/5
Option A is correct.
Step-by-step explanation:
The formula to find sin A is :
[tex]sin A = \frac{Perpendicular}{Hypotenuse}[/tex]
while the formula to find cos A is:
[tex]cosA=\frac{Base}{Hypotenuse}[/tex]
So, in the figure given:
Base = 16
Perpendicular = 12
Hypotenuse = 20
Now, finding sin A and cos A using formulas and above values
[tex]sin A = \frac{Perpendicular}{Hypotenuse}\\sin A = \frac{12}{20}\\sinA=\frac{3}{5}[/tex]
[tex]cosA=\frac{Base}{Hypotenuse}\\cosA=\frac{16}{20}\\cosA=\frac{4}{5}[/tex]
So, we found sinA= 3/5 and cosA=4/5
Option A is correct.

Answer:
y=x-3
Step-by-step explanation:
Graph y=x-5 and the point (1,-2). You want your slope to be the same for the lines to be parallel. The slope in the given equation is 1/1. Type into a graphing calculator y=x- and pick a number greater than negative five since the point (1,-2) is above the given line. Guess and checking reveals -3 to be the correct answer. Therefore, your answer is y=x-3.
