Answer: 3(x minus 5.50) = 111.75; the monthly Internet service is $42.75
Step-by-step explanation:
Given the following :
Total amount spent on internet for 3 months = $111.75
Monthly credit received on bill = $5.50
Monthly Credit of $5.50 means $5.50 is deducted from the amount being paid on thir bill monthly.
Assume their monthly internet service fee = x
The amount paid before the credit deduction each month:
Amount paid - credit
(x - $5.50)
For 3 months :
3 × (x - $5.50) = $117.75
3(x - $5.50) = $117.75
Monthly fee paid before credit deduction:
3(x - $5.50) = $117.75
3x - $16.50 = $117.75
3x = $117.75 + $16.50
3x = $128.25
x = $128.25 / 3
x = $42.75
The answer is c. Because 4.5 * 2 is 9 then you add 0.5 so the answer is 9.5
Answer:
-3:4 is The two rational numbers have to have in common.
The answer is -11/2, 9/2
Explanation
You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10
Then you solve for X in each equation.
2x+1=10 would give you 9/2
2x+1=-10 would give you -11/2
So your final solutions would be x1= -11/2 x2= 9/2
