Ok so what you're trying to do is get L by itself so to do this you move everything to the other side:
A=L*WH
=L
So you answer would be:
C
The difference between 10 and 115 is 105.
It takes a car 1 hour and 45 minutes to go 105 miles.
Or, it takes a car 105 minutes to go 105 miles.
The average speed of the car: 1 mile per minute since 105/105 = 1..
Answer:
8/5 is the answer

=8/5
Answer: the number of hotdogs that were sold is 35
the number of orders of fries is 52
Step-by-step explanation:
Let x represent the number of hotdogs that were sold.
Let y represent the number of orders of fries.
You sold a total of 87 hotdogs and orders of fried combined. This means that
x + y = 87
Each hot dog costs 1.50 and each order of fries costs 0.50. At the end of the night you made a whopping $78.50! This means that
1.5x + 0.5y = 78.5 - - - - - - - - - - -1
Substituting x = 87 - y into equation 1, it becomes
1.5(87 - y) + 0.5y = 78.5
130.5 - 1.5y + 0.5y = 78.5
- 1.5y + 0.5y = 78.5 - 130.5
- y = - 52
y = 52
Substituting y = 52 into x = 87 - y, it becomes
x = 87 - 52
x = 35
Answer:
Step-by-step explanation:
3z + 9 + 142 = 4z + 5
3z + 151 = 4z + 5
-z + 151 = 5
-z = -146
z = 146
answer is B
