Answer:

D . 58 miles

Step-by-step explanation:

In order to find the distance travelled (d) in each stage, we will use the following expression.

d = v × t

where,

v: speed

t: time

First stage

v = 70 mi/h

t = 45 min × (1 h / 60 min) = 0.75 h

d = v × t = 70 mi/h × 0.75 h = 53 mi

Second stage

v = 20 mi/h

t = 15 min × (1 h / 60 min) = 0.25 h

d = v × t = 20 mi/h × 0.25 h = 5.0 mi

The total distance tyraveled is 53 mi + 5.0 mi = 58 mi

Solve the equation. –x 8 3x = x – 6 x = –18 x = –14 x = 2 x = 4
LenKa [72]

The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.

<h3>How to find variable in an equation?</h3>

The variables of an equation can be found as follows:

–x + 8 + 3x = x – 6

The variable in the equation is x.

Therefore,

–x + 8 + 3x = x – 6

combine like terms on the left side

-x + 3x + 8 = x - 6

2x + 8 = x - 6

subtract x form both sides of the equation

2x - x + 8 = - 6

x + 8 = -6

subtract 8 from both sides

x = -6 - 8

x = - 14
