Answer:
m ≤ -15
Step-by-step explanation:
You can convert m into positive by multiplying -1 on both sides of the equation. This would also result to a -15.
Note that when an unknown variable changes its sign, the symbol becomes the opposite version of itself.
So,
-m ≥ 15
-m(-1) ≥ 15(-1)
m ≤ -15
Answer:
y =5
Step-by-step explanation:
Let's solve your equation step-by-step.
4(2y−3)+12=40
Step 1: Simplify both sides of the equation.
4(2y−3)+12=40
(4)(2y)+(4)(−3)+12=40(Distribute)
8y+−12+12=40
(8y)+(−12+12)=40(Combine Like Terms)
8y=40
8y=40
Step 2: Divide both sides by 8.
8y
8
=
40
8
y=5
Answer:
y=5
Answer:
20
Step-by-step explanation:
Add the numbers of apples you both have
Your apples + Amelia's apples = total apples
10 + 10 = 20
Step-by-step explanation:
Let's subtitute 
for the above equation:
J/-2+7 = -12
j/5 = -12
j/5 • 5 = -12 • 5
j = -60
