It would take 8 months for Comporium to cost more than Brighthouse.
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let c represent the total cost to install Wi-Fi for m number of months.
For Comporium:
For Brighthouse:
For Comporium to cost more than Brighthouse:
39.99m + 100 > 49.99m + 20
10m > 80
m > 8
It would take 8 months for Comporium to cost more than Brighthouse.

Hi
if she recieived 13 bills and 4 are 10 $? then we have 13-4= 9 20$ bills
so 4x10 +9x20 = 40+180 = 220
So yes it's true
We need to solve for x. Let's try problem b:

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

Since this is true, your answer would be:
All real numbers
------------------------------------------------------------------
Let's solve for problem c:

Let's isolate x, so subtract 1 from both sides:

Since x can't have a coefficient, divide both sides by 3:


So, only the value of 14 would make this equation true.
------------------------------------------------------------------
Let's try problem d:

Let's get our whole numbers on the right side. Add 1 to both sides:

Subtract 4x from the right side on both sides:

Since this is not true, your answer would be:
No solution
Answer:
0.7453
Step-by-step explanation:

Answer:
1/3
Step-by-step explanation:
transfer 4 to the other side then the sign will be minus
then divide 1 by 3
