Answer:
x = -2
Step-by-step explanation:
2(x + 1) = -2
Divide both sides by 2.
x + 1 =
Divide −2 by 2 to get −1.
x + 1 = -1
Subtract 1 from both sides.
x = -1 - 1
Subtract 1 from −1 to get −2.
x = -2

Answer:
10 is answer of this question
Answer:
Working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.
Step-by-step explanation:
Given that Ted can change an advertisement on a billboard in 5 hours, while Marie can do the same job in 2 hours, to determine how long it would take them if they worked together the following calculation must be performed:
Ted 1/5 in 1 hour
Marie 1/2 in 1 hour
1/5 + 1/2 = X
5X + 2X = 10
7X = 10
X = 10/7
X = 1 3/7
60/7 x 3 = 25.71
60 x 0.71 = 42.6
So, working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.
Y = 85 (vertical angles)
so answer is B) 85
