substitute 7 for y then solve for x
x = 2/3
Answer:
61.2 degrees
Step-by-step explanation:
You want to isolate x on one side of the equation and the numbers on the other side
3x + 2x + 27 = 180
3x + 2x +27 - 27 = 180-27
5x = 153
x = 153/5
x = 30.6
<DOC = 2x
2x = 30.6 x 2
61.2 degrees
We can use a variable equation to solve this. Let A represent alan's age, B represent bob's age, and C represent Cindy's age. So Bob's age would be Alan's age - 5, or a -5 = B. Then Bob's age would be double Cindy's age, so that means 2 multiplied by Cindy's age = Bob's age, or 2C = B. Your two equations are:
A - 5 = B
2C = B
Also a third equation that helps is A + B + C = 20.
Finally, here are the ages.
Alan = 11 years old
Bob = 6 years old
Cindy = 3 years old.
