Answer:
it is 8
Step-by-step explanation:
When two adjacent angles form a straight line, they are called linear pair. They add up to 180.
j + 102 = 180
j = 180 - 102
j = 78
Annie will have $70 because if you multiply 7 times 10 you get 70
Answer:
(18-7x) +1 = -9
Step-by-step explanation:
the difference between 18 and seven times a number. First seven times a number is equal to 7x. Difference means subtract, so you get 18-7x. Now one increased is +1. But we have to put 18-7x into parentheses because if we dont, 18-7x+1, simplifes into 19-7x
