Answer:
$128.40
Step-by-step explanation:
Find the total cost of the pizza before tax.
15 × 8 = 120
Set up a proportion to find the tax.
7/100 = x/120
Cross multiply
840 = 100x
Divide both sides by 100
Tax = $8.40
$120 + $8.40 = $128.40

Answer:
Part A:
0.1111111111111 = 1/9
Part B:
3
Step-by-step explanation:
Part A:
When I put 0.111111111 into my calculator I get a conversion of 1/9.
Part B:
The fraction 1/9 means that for every 9 kids he surveyed, 1 of them replied "yes."
So covert 1/9 into x/27
27/9 = 3 which means 9 goes into 27, 3 times.
Multiply 1 by 3.
1 x 3 = 3
Put into fraction form
3/27
This means 3 students out of 27 answered "yes."
Simplify it to 2x-4=8x-4
-6x=0
x=0
not sure if that counts as no solution or single solution though...
