Answer:
<h2>170</h2>
Step-by-step explanation:
given:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 + 5 + 7 = 17
since Cindy ate 30, less than Ann and Ben together so, the equation is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
<u>cindy 7 x 10 = 70
</u>
total = 170
Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
Answer:

Step-by-step explanation:
Answer:
f(-1) = 81
Step-by-step explanation:
Given the function, , we can find f(-1) by plugging in -1 into the function:
<em>f </em>(-1) = 81
Answer: D) 13y+15y^2
Step-by-step explanation:
(4y+9y)+(-8y^2-7y^2)=13y-15y^2
