If pennies and dimes come in rolls of 50 coins each, while nickels and quarters come in rolls of 40 coins each, how many dollars is 5 rolls of pennies, 6 rolls of nickels, 7 rolls of dimes, and 8 rolls of quarters?
We will have $129.5 of 5 rolls of pennies, 6 rolls of nickels, 7 rolls of dimes, and 8 rolls of quarters.
Given:
Pennies ( $0.01 ) come in rolls of 50 coins each,
Dimes ( $0.1 ) come in rolls of 50 coins each,
Nickels ( $0.05 ) come in rolls of 40 coins each,
and Quarters ( $0.25 ) come in rolls of 40 coins each.
5 rolls of pennies, 7 rolls of dimes, 6 rolls of nickels, 8 rolls of quarters came.
Thus,
[tex]\begin{aligned} \rm{Total\; Value}&=0.01 \times 50 \times 5 + 0.1 \times 50 \times 7 + 0.05 \times 40 \times 6 + 0.25 \times 40 \times 8\\&= 2.5 + 35 + 12 + 80\\&= \$129.5 \end{aligned}[/tex]

Find two fracrions in between 2/7 and 3/7 whose numerator and denominator are whole numbers
Answer:
7/21 and 8/21
Step-by-step explanation:
2/7 can be also written as 6/21 and 3/7 as 9/21
so, fraction in between 6/21 and 9/21 is 7/21 and 8/21
The two fraction in between 2/7 and 3/7 are 7/21 and 8/21.
Here,
We have to find two fraction in between 2/7 and 3/7.
What is Whole number?
The numbers which is start from 0 (zero) are called whole number.
Now,
The fraction 2/7 can be also written as,
[tex]\frac{2*3}{7*3} = \frac{6}{21}[/tex]
And, The fraction 3/7 can be also written as,
[tex]\frac{3*3}{7*3} = \frac{9}{21}[/tex]
Hence, we get;
[tex]\frac{6}{21} , \frac{7}{21} ,\frac{8}{21} ,\frac{9}{21}[/tex]
Therefore, The two fraction in between 2/7 and 3/7 are 7/21 and 8/21.

Answer:
33. D.1/3
34. D. y= x+4
35. Slope= -2/3 Y-intercept= -6
Step-by-step explanation:
For number 33. D. 1/3 is the correct answer.
Start at the point (0,2) Then, Go up 1 and Right 3.
As a result, you land in the point (3,3) This proves that the slope is 1/3.
Note: the line is increasing and going upwards, so the slope is positive.
For number 34. D. y=x+4 is the correct answer.
When writing an equation of a line, the correct format is y=mx+b. We are given both m and b. So all we have to do is plug these values into the equation y=mx+b. As a result, we get y=1x+4, which also means y=x+4
For number 35. The Correct answer is: Slope= -2/3 Y-intercept= -6
For this question I can't see all the answer choices but I know that the Slope is -2/3 and the Y-intercept is -6. Here's why: First you need to transform the equation 2x+3y=-18 into y=mx+b format. To do this, subtract -2x from both sides of the equation and you are left with 3y=-18-2x. You can flip -18 and -2x which makes the equation 3y=-2x-18. The next step is to divide both sides of the equation by 3, which gives you y=-2/3x-6. This means Slope= -2/3 and Y-intercept= -6

Write and solve an equation to find the number of miles you must drive to have the same cost for each of the
car rentals. Let m represent the number of miles.
20 plus $0.50 per mile
$30 plus 50.25 per mile
Write an equation
Answer:
20+0,5m=30+0,25m
0,5m-0,25m=30-20
0,25m=10/0,25
m=40
Step-by-step explanation:
Equation for the given condition is equals to 20+ 0.50m = 30 +0.25m. Value of the m= 40miles.
What is an equation?" Equation is defined as the algebraic expression which is represent by sign of equality."
According to the question,
m represent the number of miles
Cost for blue car rental = $20 + 0.50 per mile
= 20 + 0.50m
Cost for red car rental = $30 + 0.25 per mile
= 30 + 0.25m
Both the cars have same rentals.
Therefore,
Equation for the given condition
20 +0.50m = 30 +0.25m
⇒0.50m - 0.25m = 30 - 20
⇒0.25m = 10
⇒m = 10 / 0.25
⇒m = 40miles
Hence, equation for the given condition is equals to 20+ 0.50m = 30 +0.25m. Value of the m= 40miles.
