Answer:
x=175
Step-by-step explanation:
1st number = x
2nd number = x
3rd number = 1.6(2x)
x+x+1.6(2x)=910
x+x+3.2x=910
5.2x=910
x=175
Answer:
x = 40
Step-by-step explanation:
x + 100 + x = 180 {Straight line angles}
2x + 100 = 180 {subtract 100 from both sides}
2x = 180 - 100
2x = 80 {Divide both sides by 2)
x = 80/2
x = 40

Answer:
3
Information:
Math Team has 12 members
Regional teams are made up of 4 members
Explanation:
If you think about it simply, all you have to do is divide
Your finding how much teams can be made out of 12 people with the requirement of 4 being in each.
12 / 4 = 3
If your having a hard time with dividing you can just use repeated subtraction. So just subtract 4 from 12 until it ends in 0, and then count how much times you subtracted!
