Answer:
(x) = 
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject
y = 6x + 7 ( subtract 7 from both sides )
y - 7 = 6x ( divide both sides by 6 )
= x
Change y back into terms of x with x = (x) , then
(x) =
Answer:
25 boys.
Step-by-step explanation:
To solve this problem, first add the two parts of the ratio. 9 + 5 = 14. Then divide 70 by 14 to get 5. Since the total is 5 times the ratio total, multiply both sides of the ratio by 5. The result is 45 : 25. If you add them together, you get a total of 70. Therefore, there are 25 boys in the class.

Answer:
width = 26 inches
Step-by-step explanation:
perimeter of a rectangle= p
p= 2*L+ 2*w
L= length
w= width
The statement tell us:
L= 10+w
p=124
124=2*(10+w) +2*w
124= 20+2w+2w
124-20=4w
w=104/4
w=26 =width
The answer is C. 5x - 22y + 8z
