Solve for x.<br> 3.rº<br> 80°<br> 20°<br> A. 10<br> B. 20<br> C. 50<br> D. 80
ohaa [14]

Answer:

x = 20°

Step-by-step explanation:

The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.

3x + 2x simplifies to 5x. 5x must equal 100.

100/5 = 20.

Therefore x = 20.

ra1l [238]

Answer:

The answer is c: y = 35x + 1000

Step-by-step explanation:

Jamie starts off with 1000 which means that no matter how much more money she adds to the account she still has to add the 100 she already has. Then she is adding $35 per month so it would be positive 35 so the correct equation is

35x +1000
