The answer would be C. When you isolate X you get 4/5 turn that into a decimal you have 0.8. Then you isolate Y you get 3/5 Turn that into a decimal and you get 0.6. Therefore the solution has 1 answer.
Hope this helps
All the corners of a rectangle is equal to 90 degrees. So you need to set (x-1) and (2x+10) equal to 90 and then solve for x.
(x - 1) + (2x + 10) = 90
<em>Combine the like terms...
</em>3x + 9 = 90
<em>Subtract both sides by 9...
</em>3x + 9 - 9 = 90 - 9
3x = 81
<em>Divide both sides by 3...
</em><em>3x = 81
</em>(3x) / 3 = 81 / 3
x = 27
