Answer:

x = -4

Step-by-step explanation:

-x+7 = -6x-13

Add 6x to each side

-x+7+6x = -6x-13+6x

5x+7 = -13

Subtract 7 from each side

5x+7-7=-13-7

5x = -20

Divide by 5

5x/5 = -20/5

x = -4

1. The larger of two supplementary angles is 15 more than twice the measure of the smaller angle. Find each angle measure.Help
Anna71 [15]

Answer:

55 degrees and 125 degrees

Step-by-step explanation:

Supplementary means that they add up to 180.

x + y = 180

Let's let x be the larger angle.

x = 15 + 2y

The above equation comes from the information given, that it's 15 more than twice the smaller angle.

Now let's use substitution.

x + y = 180

(15 + 2y) + y = 180

15 + 3y = 180

3y = 165

y = 55

The smaller angle is 55. Plug this back in to the first equation to get x.

x + y = 180

x + 55 = 180

x = 125

Now that you have both, test them again just to be sure that they fit the given conditions.
