Answer:
Q = 132
P = 48
Step-by-step explanation:
Angles R + S = 180, which means
(5x + 3) + (14x + 6) = 180
19x + 9 = 180
19x = 171
x = 9
so
R = 5x + 3 = 5(9) + 3 = 48
S = 14x + 6 = 14(9) + 6 = 132
Q = 180 - R = 180 - 48 = 132
P = 180 - Q = 180 - 132 = 48
3(4x - 2) = 30
12x - 6 = 30 <em>distributed 3 on the left side</em>
<u> +6 </u> <u>+6 </u>
12x = 36

x = 3
Answer: x = 3
Answer:
B
Step-by-step explanation:
The domain is all possible values of x. Here, x is the number of $5 nontaxable items. So x must be an integer, and it can't be negative. It is possible for x to be 0. So x is all whole numbers.
