Well, to find the answer to this problem you have to change the -15 to a positive (+15) and add the two numbers together. And, 15 + 68 = +83 degrees.
So, your answer is: A. +83 degrees.
It's really easy because all your doing is changing the -15 to a positive 15 and adding the two numbers together to get your answer.
Hope I helped!

If the variable in the equation is * , then you add 13 to each side so that * would be by itself.
Answer:
30 and 20 respectively
Step-by-step explanation:
Let the number of sofas to be built be s and the number of recliners be r.
For the time part, we have the following equation:
8s + 6r = 340
For the money part:
180s + 105r = 6750
Now let’s solve these equations simultaneously.
Let’s change the form of the second equation:
180s + 17.5(6r) = 6750
From the first equation, 6r = 340 - 8s
Insert this into the third equation
180s + 17.5(340-8s) = 6750
180s + 5950 - 140s = 6750
40s = 6750 - 5950
40s = 800
s = 20
Substitute the value into the first equation
8(20) + 6r = 340
6r + 160 = 340
6r = 180
r = 30
Answer:1 inch = 0.0833333 feet so 74 x 0.0833333 = 6.16667
Step-by-step explanation:
Linear pairs are when 2 lines intersect, and are adjacent angles.
The measure of a straight angle is 180 degrees, so a linear pair<span> of angles must add up to 180 degrees.
