Let's solve the equation!
<span>3(x - 5) - 12 = 2(x - 6) + 2
</span>
Use the distributive property, which states: a(b-c) = ab - ac
3x - 3(5) - 12 = 2x - 2(6) + 2
3x - 15 - 12 = 2x - 12 + 2
3x - 27 = 2x - 10
Subtract 2x on both sides
x - 27 = -10
Add 27 on both sides.
x = 17
When x = 17, the equation 3(x - 5) - 12 = 2(x - 6) + 2 is true.

Answer:
<em>-9/10</em>
Step-by-step explanation:
Plug In: y = 3 z = -1/5
1/2z - 2/3y
Multiply:
1/2(-1/5) - 2/3(3)
Solve:
-1/10 - 2 = -.1 - 2 = -.9 = -9/10
Answer: The last paper has to be 99 over 100 to move the class average by 1 point
Step-by-step explanation:
