If you are trying to find the bigger angle, then the answer is A) Supplementary. But if you’re trying to find the small angle the answer is B) Complementary. C and D are both wrong.
Your answer is 9! Please ask questions if you need me to go into further detail. Have a good day! :)
1) 15 = 5(x + 2)
15 = 5x + 10
15 - 10 = 5x + 10 - 10
5 = 5x
5/5 = 5x/5
1 = x
2) 5n + 34 = -21(1-7n)
5n + 34 = -21 + 147n
5n + 34 = -21 + 147n
5n - 147n + 34 = -21 + 147n - 147n
-142n + 34 = -21
-142n + 34 - 34 = -21 - 34
-142n = -55
-142n/-142 = -55/-142
n = 55/142
Answer:
41
Step-by-step explanation:
Substitute in 5 and 7 into the correct spots:
(-3)(7)+2((8)(5)-9)
Multiply and simplify:
-21+2(40-9)
-21+2(31)
-21+62
41
:)
Because 6 is just 3 doubled, and when you double you will get a bigger number while multiplying
