You want to combine you like term so it will be 4x-5=532
then you want to subtract 5 from both side and you will get 4x=527
then you will want to divide 527 by 4
and get 131.75
so x=131.75
Just multiply each fraction by 100
a. is (6*100) /100 = 6 per cent
b = (3*100) / 8 = 37.5 %
do same for the last 2
Answer:
124
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180:
m<R + m<S + m<T = 180
11x + 3 + x + 15 + 2x + 8 = 180 add like terms
14x + 26 = 180 subtract 26 from both sides
14x = 154 divide both sides by 14
x = 11 to find m<R replace x with 11
11*11 + 3 = 124
C.
because a, b, and d aren't porportional
but c x is divided by 2
