X = 20
First, you move the 40 to the other side.
-2x=-40
Then, you divided -40 by -2.
x= -40/-2
x= 20
x is 20 because the negatives cancel out making it positive.
Answer: 156 miles
Step-by-step explanation:
Given, A group of cyclists went bike riding during a 7-day vacation.
Total distance they biked in first three days = 131 miles
Total distance they biked by the end of the vacation ( i.e. in 7 days ) = 287 miles
Then, the total distance they biked in last four days would be=
(Total distance they biked in 7 days ) - (Total distance they biked in first 3 days )
= 287 - 131 miles
= 156 miles
Hence, they biked 156 miles in last 4 days.

Answer:
2.75
Step-by-step explanation:
Here, we want to find which part of the formula corresponds to the cost of movie tickets in 1980
The expression to find the cost is
2.75 + 0.10x
Now, x is the time since 1980
1980 is thus the starting position. The value of x at this point is 0, we simply thus make a substitution;
2.75 + 0.1(0)
=
2.75
8j³+3j²+7-(3j³-7j²-7j-12)
8j³+3j²+7-3j³+7j²+7j+12
8j³-3j³+3j²+7j²+7j+7+12
5j³+10j²+7j+19
