Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6
Two angles are vertical
Hypothesis is after “if” but before “then”
R=0.5772 (im trying to post it says wrong answer so not sure)
Answer:
i would say B a stick shift
Step-by-step explanation:
It would be 156 since both angles add up to the angle
