The answer is B y = 5x - 14
Answer:
(42.26/100)*120 = $50.712
Step-by-step explanation:
An equation is formed of two equal expressions. The number of gigabytes that is used in a month so that the two phone plans cost the same amount is 11.6667 Gigabyte.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let c represent the cost of a phone plan, m represent the number of months, and g represent the number of gigabytes of data used each month.
Equation1: C = 40m + 3.5mg = (40+3.5g)m
Equation2: C = 75m + 0.5mg = (75+0.5g)m
Equating C,
(40+3.5g)m = (75+0.5g)m
40 + 3.5g = 75 + 0.5g
3g = 35
g = 11.6667 gigabyte of data per month
Hence, the number of gigabytes that is used in a month so that the two phone plans cost the same amount is 11.6667 Gigabyte.

Somebody else posted this exact same question just yesterday.
HE didn't include the list of choices either.
Here are a couple of equations that model the situation:
Power = 0.2 (length of side of a square solar panel)²
or
Power = 0.2 (length of the solar panel) (width of the solar panel) .
