Two cars travel along a highway at the same speed.
Mazyrski [523]

Answer:

30 mins

Step-by-step explanation:

<em>speed = distance/ time </em>

speed of car A

= 20/ 12 km/ min

= 5/ 3 km/ min

also, speed of car A = speed of car B

speed of car B = 5/ 3 km/ min = 50km / time taken (in mins)

\frac{5}{3}  =  \frac{50}{t}

5t  = 150

t = 30

=> t = 30 mins

Solve for x.<br> -5/4x = -30<br> Simplify your answer as much as possible.
zlopas [31]

Answer:

The answer is x=24.

Step-by-step explanation:

This is a one step equation, so it is simple, as shown.

In order to isolate the variable, you need to multiply each side of the equation by the fraction's reciprocal. In this case, it is -4/5.

Thus, x= -30 x -4/5

All things said, the answer is x=24.

I hope this helped!!

HELP PLZ I DON'T UNDERTSTAND IT
nasty-shy [4]

Answer:

The answer is A.

Step-by-step explanation:

Keeping point y as a reference, we know that it was rotated 180 degrees around the origin. I could tell this because y moved from one corner to another, if it was rotated 90 degrees it would move in a different direction. We also know it moved clockwise because if it moved counter clockwise it would have a different location.

We also know that it was shifted across the x-axis because it moved to the right. If it moved downwards it would have moved in the y direction.

Hope this helps.
