Answer:
(-5,-3)
Step-by-step explanation:
In this case to find the solution you could use substitution. This way you can solve without changing the equation over again.
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b - 2 = 4
-2b = 6
b = -3
Plug back in to find value a
a = (-3) - 2
a = -5
Check your answer before submitting
(-5) - 3(-3) = 4
-5 + 9 = 4
4 = 4
Hope this helps
A) angles 4 and 5
b) angles 3 and 7
c) angles 1 and 8
Answer: 1102 minutes
Explanation: Let x be the number of minutes Jim used 105.60 = 75 + 0.30 ( x − 1000 ) ⇒ 105.60 = 75 + 0.30 x − 300 ⇒ 105.60 = 0.30 x − 225
I’m pretty sure the equation is 28-f=n
and the answer is 2.
