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.

Find the slope of 10y = 7x + 5.
Round to the third.
Answer:
0.7
Step-by-step explanation:
10y = 7x + 5
Divide both sides by 10.
y = 7x/10 + 5/10
y = 0.7x + 0.5
On a straight line of the form y = kx + m, k is the slope of the line.
In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

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.

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.

Gary lost an additional 18 yards and gained 58 yards in the second quarter. Write an equation to represent his total yardage for the first half of the game.
Answer:
+73 yards.
Step-by-step explanation:
Since we have the first two quarters, we can simply work out the yardage for each game and add them together to get the total.
