Answer:
y = 2.1x +5, 21 miles
Step-by-step explanation:
We will denote miles as "x"
Since she tipped the driver $5, that is a flat rate and that will be our y-intercept. Since it costs $2.10 per mile, we need to multiply that number by the number of miles
So our equation will be y = 2.1x +5
In order to figure out how many miles Ann lives from the airport, we need to substitute y for her grand total that she was charged
This gives us 49.10 = 2.10x + 5
First we need to subtract 5 from each side to get 44.10 = 2.10x
We then need to divide both sides by 2.10 to get 21 = x
Ann drove 21 miles
Answer:
3.25 × 10^6
Step-by-step explanation:
7.57×10^6 - 4.32 × 10^6
(7.57 - 4.32) × 10^6
<u>3.25 × 10^6</u>
Answer:
Step-by-step explanation:
Distance = speed * time
- d = 12 *1 1/2 = 12*1.5 = 18
The answer is 3x^3+15x^2-12x.
25+15•3= 70 dollars she spent on the hair salon..... dang lotsa money
