Answer:
Step-by-step explanation:
I'll call the soccer balls, baseballs and socks a,b,c respectively.
25.
a. ax + 3b
b. 3b + xc
26. The 2 expressions can only be equivalent if a.x = x.c, meaning a has to be equal to c, which is not true. So they're not equivalent.
27. 2 1/2 = 5/2
A soccer ball is 15 : 6 = 15/6 = 5/2 the cost of a baseball
So yes, soccer balls are 5/2 more expensive than baseballs.
