Two cars are traveling on two different routes, one 43 miles longer than the other. The car traveling on the longer route travel
Anestetic [448]

Answer:

x1 = 275 miles (shorter)

x2 = 318 miles (longer)

Step-by-step explanation:

Let

x1 = be the shorter route

v1 = speed of the car in the shorter route

t1 = time it took to cover shorter route

x2 = the longer route

v2 = speed of the car in the longer route

t2 = time it took to cover longer route


x1 + 43 = x2   (1)

v2 = v1 -2   (2)


v2 = x2/t2 = x2/6

v1 = x1/t1 = x1/5


This means that

v2 = v1 -2   =>

x2/6 = x1/5 -2

The system of equations results

a.   x1 -x2 = -43

b.  x1/5 - x2/6 = 2

Solving this system of equations, we find that

x1 = 275 miles

x2 = 318 miles

If an item costs $45 and we must pay 6% sales tax, how much will we pay for the item?
Gennadij [26K]

$47.70

$45 with 6% sales tax

6%=.06

To find total amount multiply by 1.06 or multiply by .06 and that is tax amount and then add it to the $45

$45*.06=2.70 amount of tax

$45*1.06=47.70 total amount paid

Any questions feel free to ask. Have a great day!
