Step-by-step explanation:
Answer:
x= 9
Step-by-step explanation:
(3x + 4) and 50 are complementary angle
=> (3x + 4) + 50 = 90
-> 3x+4 = 40
-> 3x = 36
-> x= 9

Use distributive property: a(b - c) = ab - ac

Answer:\
I’m pretty sure the slope is 7/4
2x+3x+5x=90
10x=90
x=9
2 times 9=18
3 times 9=27
5 times 9=45
$18, $27, and $45.
