PLEASE HELP!<br> solve for x and then find measure for angle b
Bezzdna [24]
<h3>Answers:</h3><h3>x = 12</h3><h3>Angle B = 45 degrees</h3>

===========================================================

Explanation:

Angles A and B are alternate exterior angles.

Due to the parallel lines, alternate exterior angles are congruent

A = B

5x-15 = 2x+21

5x-2x = 21+15

3x = 36

x = 36/3

x = 12

Use this x value to find the measure of angle B

angle B = 2x+21

angle B = 2*12+21

angle B = 24+21

angle B = 45 degrees

As a check,

angle A = 5x-15

angle A = 5*12+15

angle A = 60-15

angle A = 45 degrees

Since A and B are both 45 degrees, this confirms the correct x value

Last month, Justina dog ate 50 cans of dog food in 30 days. How many cans should Justin buy for the next 6 days
natali 33 [55]

Answer:

The answer is 7 2/3 cans for the next 6 days.

Step-by-step explanation:

Given: The dog ate 50 cans in 30 days.

To get how many cans per day, divide:

50/30 = 1 2/3 cans per day.

To get how many cans for 6 days, multiply:

6 * 1 2/3 = 18/3 + 5/3 = 23/3 = 7 2/3 cans or 7.667 in decimal form.

Hope this helps!! Have an Awesome day!!! :-)

DiKsa [7]

Answer:

B. 1/2

Step-by-step explanation:

You can see that when two weeks that pass, the plant grows one inch. This rate can be written as 1 inch : 2 weeks. But, we need to find the unit rate. To find the unit rate, or how many inches the plant grows per week, we divide both by 2.

1/2 inch : 1 week

1/2

I Hope That This Helps! :)
