Answer:C =$65 + $30G
Step-by-step explanation:
Given that :
Base fee charge = $65
Overage charge = $30 / per gigabyte for data that exceeds 2 gigabyte
C = cost ; G = total amount of gigabyte
Equation to represent plan; if more than 2 gigabyte are used :
Cost (C) = Base charge + (average charge * amount of gigabyte)
C = $65 + ($30 * G)
C =$65 + $30G
Answer:
$15.56
Step-by-step explanation:
So start by doing a 10% tip, because you just move the decimal place over by 1, so $1.35, and then divide that by 2 to get 5% which is .68, and add them to get 2.03. You can get the same answer by multiplying 0.15 to 13.53. 13.53 + 2.03 is 15.56. Hope this helped and have an awesome day!
Y = 4x + 4
-8x + 3y = 5
-8x + 3(4x + 4) = 5
-8x + 12x + 12 = 5
-8x + 12x = 5 - 12
4x = -7
x = -7/4
y = 4x + 4
y = 4(-7/4) + 4
y = -7 + 4
y = -3
solution is (-7/4,-3)
Answer:
r = -3
Step-by-step explanation:
We need to isolate r...
-8r+12=36
Subtract 12 from both sides
-8r=24
Divide both sides by -8
r= -3
We can check this answer...
-8r+12=36
-8(-3)+12=36
24+12=36
36=36 --> correct!
r = -3
