Which pair shows equivalent expressions?
A.2(2/5x + 2)=2 2/5x + 1
B.2(2/5x + 2)=4/5x + 4
C.2(2/5x + 4)=4/5x + 2
D.2(2/5x + 4)=2 2/5x + 8
Solution:
Let us distribute 2 inside the parenthesis.
That is, we use distributive property:
a(b+c)=ab+ac
So,
Answer:Option (b)
Applying distributive property, a(b+c)=ab+ac
So, Option (B) is correct.

Answer:
y=7/24x+625/24
Step-by-step explanation:
-7x+24y=-25"2
-7x+24y=625
+7x +7x
24y=7x+625
divide 24
y=7/24x+625/24
Got this for my mathswatch too
