Translate the phrase into an algebraic three dollars more than twice the cost of a bowl of soups 2+3
3(2c)
3+2c
2+2c
Answer:
3+2c
Step-by-step explanation:
To translate the phrase into an algebraic expression, you have to analyze the information provided. Three dollars more than twice the cost of a bowl of soups means that given that c is the costs of a bowl of soup, you have to multiply c for 2 as the phrase says twice the cost. Also, it says three dollars more which means that you have to add 3. According to this, the expression is: 3+2c.
The athlete drink 16 ounces of water every two hours starting at 7:30 AM and continuing for the next 14 hours. A) how many quarts did the athlete consume? B) how many pints of water did the athlete consume?
When the athlete drink 16 ounces of water every two hours for the next 14 hours,
(A) The athlete consumes 3.5 quartz of water.
(B) The athlete consumes 7 pints of water.
Conversions(1) Ounce to Pints16 ounces = 1 pint
(2) Quarts to Ounces1 quart = 32 ounces.
(A) Calculation for the water consumed by athlete in quarts:The total duration for which athlete consumes the water is 14 hours with a after every 2 hours.
The total number of times the water consumed by athlete is 14/2 = 7.
Covert the 16 ounces of water in quarts
= 16/ 32
=1/2
The total quantity of water consumed in quarts is
= 7×(1/2)
= 3.5 quarts
Thus, the amount of water consumed by athlete in entire 14 hours is 3.5 quarts.
(B) Calculation for the water consumed by athlete in pints:The total duration for which athlete consumes the water is 14 hours with a after every 2 hours.
The total number of times the water consumed by athlete is 14/2 = 7.
Convert 16 ounce of water into pint
= 16/16
= 1
The total quantity of water consumed in pints is
= 7×1
= 7
Thus, the amount of water consumed by athlete in entire 14 hours is 7 pints.

Write an expression that gives the area of the shaded region in the figure.
Answer:
Area = 88 square units
Step-by-step explanation:
The length of the blue rectangle can be found by subtracting 15 and 4, which equals 11. The width of the blue rectangle can be found by subtracting 6 from 14, which equals 8.
area = length x width
area = 11 x 8
area = 88 square units
Zack needs $299.99 to buy the new bike he wants. He has saved $150 so far toward the new bike. From this week on, he will save $12.50 per week toward the new bike. Ten weeks from now, how much more money will he still need to save to buy the bike?
$24.99
$29.99
$127.49
$137.49
Answer:
The answer is $24.99
The solution is Option A.
The equation of line is y = 12.5x + 150 , where x is the number of weeks
The amount Zack needs after 10 weeks to buy the bike is $ 24.99
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The price of the bike Zack needs to buy = $ 299.99
The initial amount with Zack = $ 150
The amount Zack saves in a week = $ 12.50
The number of weeks = x
The amount Zack saves in x weeks = 12.5x
So , the total amount with Zack after x week is given by the equation ,
Total amount with Zack after x week y = amount Zack saves in x weeks + initial amount with Zack
Substituting the values in the equation , we get
Total amount with Zack after x week y = 12.5x + 150
Now , after 10 weeks , the amount with Zack is
Substitute the value of x as 10 in the equation , we get
y = 12.5x + 150
y = 12.5 ( 10 ) + 150
y = 125 + 150
y = $ 275
Now , the amount left to buy the bike = price of the bike Zack needs to buy - amount with Zack after 10 weeks
Substituting the values in the equation , we get
Amount left to buy the bike A = $ 299.99 - $ 275
Amount left to buy the bike A = $ 24.99
Therefore , the value of A is $ 24.99
Hence , the amount Zack needs is $ 24.99

Step-by-step explanation:
[tex]2(4x+3)=x+1[/tex]
[tex]8x+6=x+1[/tex]
[tex]8x-x=1-6[/tex]
[tex]7x=-5[/tex]
[tex]x=\frac{-5}{7}[/tex]
Answer:
x = -5/7
Step-by-step explanation:
2(4x+3)=x+1
Distribute
8x +6 = x+1
Subtract x from each side
8x+6-x = x+1-x
7x+6 = 1
Subtract 6 from each side
7x+6-6 = 1-6
7x =-5
Divide each side by 7
7x/7 = -5/7
x = -5/7
Josh paid for four books with three $20 bills he received $12 in change each book was the same price how much did each book cost
Three $20 bills is a total of $60
$60 - $12 = $48
He spent a total of $48 on the books
Divide the total spent by the number of books:
48 / 3 = 16
Each book cost $16
Answer:$12 per book
Step-by-step explanation: $20 x 3= $60
If you have $12 change you minus that from the $60
Now that is $48 for 4 books.
To work out one book you do $48/4 which is $12 per book.

Answer: The length of point A(-3,1) and B(2,6) is [tex]5\sqrt{2}\text{ units}[/tex] .
Step-by-step explanation:
We know that the distance between the two points (a,b) and (c,d) is given by :-
[tex]d=\sqrt{(a-c)^2+(b-d)^2}[/tex]
Given points = A(-3,1) and B(2,6)
Therefore the distance between the points A(-3,1) and B(2,6) is given by :-
[tex]d=\sqrt{(-3-2)^2+(1-6)^2}\\\\\Rightarrow\ d=\sqrt{(-5)^2+(-5)^2}\\\\\Rightarrow\ d=\sqrt{25+25}\\\\\Rightarrow\ d=\sqrt{50}\\\\\Rightarrow\ d=\sqrt{25\times2}\\\\\Rightarrow\ d=\sqrt{5^2\times2}\\\\\Rightarrow\ d=5\sqrt{2}\text{ units}[/tex]
Hence, the length of point A(-3,1) and B(2,6) is [tex]5\sqrt{2}\text{ units}[/tex] .

The amount of money in Alexander’s account is, = 4000 − 70, where is the amount in dollars and is the time in weeks.
a) Which variable is independent and which is dependent?
Answer: Dependent is -70x and independent is 4000
b) In which week will there be $1701 in the account?
Answer:
y=4000-70(x)
1701=4000-70(x)
-70x=1701-4000
-70x= -2299
x=-2299/-70
x=2299/70
x=32.843
x=33
c) How much will the amount in Alexander’s account change if the time increases by 15 weeks?
Answer:
y=4000-70(x)
y=4000-70(15)
y=2950
Answer:
yes you are correct
Step-by-step explanation:
The answers are a) y is the dependent variable, x is the independent value. b) 33 weeks and c) $2950
What are dependent and independent variables?The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Given that, The amount of money in Alexander’s account is, y = 4000 − 70x, where y is the amount in dollars and x is the time in weeks.
a) Here, y is the dependent variable as it depends on the value of x, and x is the independent value.
b) We have, total amount = $1701
Therefore, put y = $1701
$1701 = 4000 − 70x
70x = 2999
x = 32.84 ≈ 33 weeks
c) In 15 weeks the amount will be =
y = 4000 - 70(15)
= $2950
Hence, the answers are a) y is the dependent variable, x is the independent value. b) 33 weeks and c) $2950

BRAINLIEST ANSWER Twice the difference of a number and 4 is equal to three times the sum of the number and 4. Find the number.
Answer: -20
Step-by-step explanation:
We can set up an equations with the conditions we are given. Let's use x for the missing number.
2(x-4)=3(x+4)
2x-8=3x+12
-20=x
Answer:
see below
Step-by-step explanation:
2(x-4) =3(x+4)
sum is addition
difference is subtraction
2 is multiply by2
solve 2(x-4) =3(x+4) distribute on both sides
2x - 8 = 3x + 12 add 8 on both sides
2x = 3x + 20 subtract 3x on both sides
-x = 20 multiply by -1
x = -20

100pts: What is the slope of the following curve at x = n, for an arbitrarily chosen integer n?:
y = 3x^2 - 37x + 6
Answer:
6n -37
Step-by-step explanation:
The slope would be the derivative of the function
dy/dx = 6x - 37 evaluated at the point n
dy/dx = 6n -37
Answer:
6n - 37
Step-by-step explanation:
The derivative of the function f(x) gives the gradient (slope) of the tangent to the graph of y = f(x) at the point (x, y).
Given:
[tex]y=3x^2-37x+6[/tex]
Therefore, the gradient (slope) of the given curve at x is:
[tex]\implies \dfrac{dy}{dx}=2 \cdot 3x^{2-1}-37x^{1-1}+0[/tex]
[tex]\implies \dfrac{dy}{dx}=6x-37[/tex]
To find the slope, simply substitute x for n:
[tex]\implies 6n-37[/tex]
