Answer:
cost of peach pie : 12
cost of cherry : 18
Step-by-step explanation:
Edy : 7x+7y =210
Alex : 7x+10y=264
x=12 , y=18
solve: (7x+7y)-(7x+10y)=210-264
-3y=54
y=54/3=18 for cherry pie
7x+7y=210
7x+7(18)=210 ⇒ 7x=210-126 ⇒ x=84/7=12
cost of peach pie : 12
cost of cherry : 18
Answer:
B = 3y, D = 27, C = 9y
Step-by-step explanation:
Since the top side is equal to y + 9, we can find the areas really easily.
B is equal to 3*y, which is 3y.
D is equal to 3*9, which is 27.
C is equal to y*9, which is 9y.
Cheers!
