4x+7=35
4x=28
x=7
A corresponding solution of the matching equation is a fancier way of telling you to find the number that represents x
Answer:
6(8x-2)
48x- 12 (this is the answer)
Step-by-step explanation:
to do those, you use the distributive property, which is taking the number outside the parenthesis and multiplying it by everything inside of it
Percent increase/decrease is:
(Change/original amount)x100
(.25/2.35)x100= 10.6%
Answer:
The inverse is 1/3 (x+1)
Step-by-step explanation:
y = 3x-1
Exchange x and y
x = 3y-1
Solve for y
Add 1 to each side
x+1 = 3y-1+1
x+1 = 3y
Divide each side by 3
(x+1)/3 = 3y/3
1/3(x+1) =y
The inverse is 1/3 (x+1)
X=9
3x-12=x+6
2x-12=6
2x=18
X=9
