Answer:
a= (c-b)/x
Step-by-step explanation:
subtract b to both sides
divide x to both sides
leaving a by itself.
Solution: We are given:
Sales tax
The pre-tax price of the supplies
We have to find the total cost of the supplies.
We first need to find the sales tax on the price of supplies. The sales tax amount is:
Therefore, the total cost of the supplies = pre-tax price of the sales + sales tax amount
=$48 + $3.36
=$51.36
98 - x² = 0
x² = 98
x = ±√98
Lets factor 98
98 | 2
49 | 7
7 | 7
1
So, 98 = 2 . 7 . 7 = 2 . 7²
x = ±√2.7²
x = ±7√2
Answer:
9/8 is simplest form
1.125 is in decimal form

Answer:
Step-by-step explanation:
Charging by the quarter mile is for purpose of making that particular taxi service seem cheaper than the others when they post a per mile charge. If this taxi company is charging .50 per 1/4 mile, they are charging $2 per mile. So we will base our equation on the per mile charge, not the per quarter-mile charge. If x is the number of mile driven (our uknown), and we have a flat fee of $2.50 regardless of how many miles we are driven, the cost function in terms of miles is
C(x) = 2x + 2.50
If we are driven 5 miles, then
C(5) = 2(5) + 2.50 so
C(5) = 10 + 2.50 and
C(5) = $12.50
It would cost $12.50 to be driven 5 miles
