Ataxicab ride costs $2.50 plus $1.10 per mile. if the total cost of the trip is $21.20, how many miles did the passenger travel? let x represent the number of miles

The passenger will travel 17 miles.

Step-by-step explanation:

Since we have given that

Cost of a taxicab ride = $2.50

Cost of per mile = $1.10

Total cost of the trip = $21.20

Let number of miles the passenger travel be x

According to equation,

Hence, the passenger will travel 17 miles.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
