I'd say the 3rd one. I haven't done this stuff in 2 years ... me forgot. But if it's not right, then the 1st one!
I want you to know you're smart and you can do this! Good luck!
<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
Answer:
x=0.875
Step-by-step explanation:
3x-6=2-5x
Add 6 on both sides (6+2)
2x=8-5x
Add 5x on both sides
7x=8
Divide 7 from both sides
x=0.875
Cannot reduce, it is already in simplest form. You can convert it to a decimal though, 0.671875

Answer: 76/4995</h3>
========================================================
Explanation:
x = 0.0152152...
10x = 0.152152...
10000x = 152.152...
Subtract the last two equations to find that
- 10000x-10x becomes 9990x on the left side
- 152.152... - 0.152152... becomes 152 on the right side
We're left with the equation 9990x = 152 which solves to x = 152/9990
Divide both parts of that fraction by 2 so that the fraction fully reduces to 76/4995 which is the final answer
You can use your calculator to see that 76/4995 = 0.0152152152152... which confirms the answer.
