5⁰ = 1
5¹ = 5
5² = 25
5³ = 125
5⁴ = 625
5⁵ = 3125
To have infinite solutions both equations need to be equal
Since they subtract 5 from the right side, subtract 5 from the left side.
X is multiplied by 1/2 on the left , so multiply x by 1/2 on the right side.
1/2x -5 = 1/2x-5
Answer: 1 1/3
Step-by-step explanation:
-4 + 5 = 1
-1/3 + 2/3 = 1/3
OR
Turn them both into mixed numbers: -13/3 + 17/3
-13/3 + 17/3 = 4/3 = 1 1/3
So first we write out their respective charges
A=65+30x (x=hours of A)
B=30+47.5y (x= hours of B)
we want to know when A and B are equal so just set them to be equal
65+30x=30+47.5x
subtract 30 from both sides
35+30x=47.5x
multiplyboth sides by 2 to get rid of the nasty decimal
70+60x=95x
subtract 60x from both sides
70=35x
divide both sides by 35
2=x
they must work 2 hours for them to be equal
