X + y = 13......x = 13 - y
2x - 3y = 1
2(13 - y) - 3y = 1
26 - 2y - 3y = 1
-2y - 3y = 1 - 26
-5y = -25
y = -25/-5
y = 5
x + y = 13
x + 5 = 13
x = 13 - 5
x = 8
<span>so, x = 8 and y = 5</span>
The answer is 77/60.
When dividing 2 fractions the way I learned was to multiply the first fraction with the reciprocal of the second number.
so it would be 11/12 x 7/5
and when you multiply that you get 77/60
Hope I helped!
False.
Adjacent angles are simply next to each other connected. This does not mean that they have the same measure. Therefore they are NOT congruent. <span />
