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 factor is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
cindy 7 x 10 =<u> 70 </u>
total = 170

Answer:
x = -5 y = 12
Step-by-step explanation:
-3x + 3y = 3
-5x + y = 13
y = 13 +5x
-3x + (13+5x) = 3
x = -5
-5(-5) + y = 13
y= 12
