Answer:
a = -20
Step-by-step explanation:
In this question, you would solve for "a".
Solve:
8(a + 30)=80
Use the distributive property.
8a + 240 = 80
Subtract both sides by 240
8a = -160
Divide both sides by 8.
a = -20
Your final answer would be a = -20

Answer:
1/80
Step-by-step explanation:
probability of selecting one specific boy is 1/8
probability of selecting one specific girl is 1/10
multiply the probabilities to get 1/80
First of all we group our m's together.
So first add
5m + 4m = 9m
Now lets set up our equation again
9m = 72 .... divide both sides by 9 to get m alone
÷9 = ÷9
************ now m is alone on the left side and we solve on the right side.
m = 8
So your answer is
m = 8
