Ruby's hours will represent x+6
Svetlana's hours will represent 4(x+6)
Issac will represent x.
The equation would read:
x+(x+6)+(4(x+6))=126
x+x+6+4x+24=126
6x+30=126
Subtract 30 from both sides.
6x=96
Divide 6 on both sides to get x by itself.
x=16
So:
Issac worked 16 hours
Ruby worked 22 hours
Svetlana worked 88 hours.
To check your answer, plug in the values:
16+22+88=126
126=126
Hope this helps.
Answer:
It 5 would not be x
Step-by-step explanation:
If 5 was x, then it would be equivalent, because 5+3 = 8. I hope this helped.
Use the formula
a_n = a_1•r^(n-1)
a_23 = 25•(1.8)^(23 - 1)
Can you finish?
X=-6
You get all the X to one side, and all the numbers to the other. Then divide. Work is shown in image below.
