Angle 5x+7 is equal to the the sum of its remote interior angles, which we are given as x+15 and 6x-26.  Therefore, 5x+7=x+15+6x-26.  We will combine like terms to get 5x+7=7x-11.  Move the 7x over to the other side by subtraction and the 7 to the other side by subtraction to get -2x = -18.  That leaves us with an x value of 9.  There you go!

if julie ran 3.6 miles from home to the gym and then walked 0.7 miles to the store she then ran from the store home if her total
o-na [289]
So,

Home ---- gym = 3.6 mi.
gym   ---- store = .7 mi.
store ----- home = x

3.6 + .7 + x = 7.2 mi.

Collect Like Terms

4.3 + x = 7.2

Subtract 4.3 from both sides
x = 2.9

The distance from the store to her home is 2.9 miles.

A car that travels 20 miles in LaTeX: \frac{1}{2}1 2 hour at constant speed is traveling at the same speed as a car that travels
charle [14.2K]

Answer:

10 miles per 1/4 hour

40 miles per hour

Step-by-step explanation:

Given that:

A car travels 20 miles in 1/2 hour

Miles traveled per hour :

(20 * 2) / 1 = 40 miles per hour

Mile traveled in 1/4 hour :

Distance = speed * time

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

Car traveling 30 miles in 3/4 hours

(30 * 4) /3 = 120 / 3 = 40 miles per hour

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
