i think the answers are A, C and D
Step-by-step explanation:
You use the equation given to solve the problem.
x= 4x9
X=36
The four is for the amount of people. The nine is the cost.
For the questions where you have to find out how much each person paid you would have to divided the amount by the number of people.
So, 36/9= 4.30
Therefore each person paid $4.30.

Answer:
C) 60.
Step-by-step explanation:
Okay, I do math a little bit different than other kids... No worries though, its still correct.
First, find out how many times five can be put into a hundred. You should have gotten 20.
Now, we can use the twenty we got. Multiply 20 by the ratio of the boys. So 20 * 3 = 60.
Girls would be
20 * 2 = 40.
Those two numbers add up to a hundred so its all good. ^-^
Hope I helped!!
Answer:
x = 65 degrees
Step-by-step explanation:
x° + x° + 50° = 180°
2x + 50° = 180°
2x = 180° - 50°
2x = 130°
x = 130°/2
x = 65°
-18x-17=-53 /add 17 to both sides
-18x-17+17=-53+17
-18x=-36
x=(-36)/(-18)
x=2
