Answer:x=7
Step-by-step explanation:
180=112+9x+5
Collect like terms
180-112-5=9x
63=9x
Divide both sides by 9
63/9=9x/9
7=x
x=7
Answer:
5/8
Step-by-step explanation:
28x + 4 can be factorised because 28 is a multiple of 4
so it can become
4(7x+1)
35x + 5 can be also factorised because 35 is a multiple of 5
5(7x+1)
we can now rewrite the expression as
6/4(7x+1) * 5(7x+1)/12
we can “eliminate” the two 7x+1 and simplify 6 with 12
so it remains
1/4 * 5/2 = 5/8
Answer:
A
Step-by-step explanation:
The answer is A as the height starts at 36 and decreases by 9 inches vertically every 12 inches it goes down horizontally.
If you turn this into an equation, you get y = -(9/12)x+36.
Then, you simplify this to y = -(3/4)x+36, which is A.
