1 answer:

7 0

If you would like to solve the system of equations, you can do this using the following steps:

x = y - 3
x + 3y = 13 ... y - 3 + 3y = 13
___________
<span>y - 3 + 3y = 13
</span>4y = 13 + 3
4y = 16
y = 4

<span>x = y - 3 = 4 - 3 = 1

(x, y) = (1, 4)
</span>
The correct result would be A) (1, 4).

Remark

The angles are marked as alternate interior angles. To be parallel, they must be equal. In other words x - 20 must equal 52. That's all you have to do. Just equate the 2 givens and solve.

Givens

x - 20 is one angle

52 is the other.

Solution

x - 20 = 52 Add 20 to both sides.

x - 20 + 20 = 52 +20 Combine

x = 72

**Ms. Gayle is driving to work. She travels 10 miles in 10 minutes. How fast is Ms. Gayle traveling?

Dimas [21]

Answer:

60 mph

Step-by-step explanation:

Ms. Gayle drives 10 miles in just 10 minutes. To find out how fast she was going we need to turn the minutes into hours. There are 60 minutes in an hour, so we multiply the miles and minutes by 60.

Ms. Gayle drives 60 miles in an hour.

This means she is traveling at 60 mph.

I hope that this helps! :)
