Answer:
x=7
Step-by-step explanation:
14/28=x/14
x=7
Anything multiplied by 0 =0
So what is left is 90x100x12x13x34 which is=47,736,000
The equation is 30x + 25
since the x is with the 30, that would be the cost per lesson, because you would multiply 30 by the number of lessons(x)
12 because if u had 3 groups of 4 that would be 3+3+3+3
