Answer:
a) 6 gigabytes
b) $100
Step-by-step explanation:
Let c represent the total cost in dollars and d represent the amount of data used in gigabytes.
For the first smartphone
One smartphone plan costs $52 per month for talk and messaging and $8 per gigabyte of data used each month.
Equation =
c = 52 + 8d
For the Second smartphone
A second smartphone plan costs $82 per month for talk and messaging and $3 per gigabyte of data used each month.
Equation =>
c = 82 + 3d
How many gigabytes would have to be used for the plans to cost the same?
We would equate both cost to each other
52 + 8d = 82 + 3d
Collect like terms
8d - 3d = 82 - 52
5d = 30
d = 30/5
d = 6
Therefore,
a) The number of gigabytes for the cost of both Smartphone data plans to be the same = 6 gigabytes.
b) The cost of both plans if 6 gigabytes is used =>
c = 52 + 8d
c = 52 + 8 × 6
c = $100
Answer:
j=2
Step-by-step explanation:
<em>First, subtract by 5 from both sides of equation.</em>
<em>5-j-5=3-5</em>
<em>Simplify.</em>
<em>3-5=-2</em>
<em>-j=-2</em>
<em>Divide by -1 from both sides of equation.</em>
<em>-j/-1=-2/-1</em>
<em>Simplify, to find the answer.</em>
<em>-2/-1=2</em>
<em>It change negative to positive.</em>
<em>j=2 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>
