Johnny has $12 less than Sarah. Sarah has $35 less than Carla. In total, they have $143. How much money does each of them have?
1 answer:
Answer:
Step-by-step explanation:
Amount with Carla = $ x
Amount with Sarah = x - 35
Amount with Johnny = x - 35 - 12
x + x -35 + x - 35 -12 = 143
3x - 82 = 143
3x = 143 + 82
3x = 225
x = 225/3
x = 75
Amount with Carla = $ 75
Amount with Sarah = 75 - 35 = $ 40
Amount with Johnny = 40 - 12 = $ 28

If you follow the steps of PEMDAS it should be Multiply by 3,subtract 2.
I would say you cannot use a rectangle. Or a circle. One of those.
Through exterior angle theorem we now that...
x+13+63=3x
2x=76
x=38
m<CVU=3x=114 degrees
