1.
(x/2) - 7 = 11
2.
2x + 7 = 27
3.
2x - 5 = 25
Hope this helped!! (:
In order to solve this problem, we must solve an equation.
First, we need to define our unknown.
Let's call our number "n".
So, the sum of the number and 6 is the same as saying n+6
Then we need to multiply it by 2 (since it's twice the sum)
2(n+6)
This whole thing is equal to three times of the difference of the number and 8
n-8 is equal to the difference between the number and 8, then we need to multiply it by three.
3(n-8)
now, we set both sides equal and solve

The number is 36
Answer:
D
Step-by-step explanation:
12-y=2x-5
+5 +5 ( add 5 to both sides)
17-y=2x
-17 -17 (Subtract 17 to get y by itself)
-y=2x-17
divide by -1 because y cant be negative
y=-2x+17
m=-2 and y-intercept= 17
I hope thats right :)
8 3/5 - (1 1/2* 3 1/5)
= 43/5 - 24/5
= 19/5
= 3 4/5
Final answer: 3 4/5~
