Answer:

(x + 7)² + ( y - 8)² = 158

Step-by-step explanation:

x² + 14x + y² - 16y - 45 = 0

x² + 14x + y² - 16y        = 45        

x² + 14x + 49 + y² - 16y  + 64       = 45  + 49 +64

(x² + 14x + 49) + (y² - 16y  + 64) = 158

(x + 7)² + ( y - 8)² = 158

Answer:

170

Step-by-step explanation:

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

cindy 7 x 10 = 70  

total            = 170
