Gavin drank 3/4 of a liter of orange juice from the container, which was 3/8 of the orange juice that was originally in the container. How much orange juice was originally in the container?
Answers
Answer:
Originally there were 2 liters.
Step-by-step explanation:
--
3/8 of the orange juice = 3/4 liter
1/8 of the orange juice = 3/4 ÷ 3
1/8 of the orange juice = 3/4 x 1/3
1/8 of the orange juice = 1/4 liter
Find 8/8, which is one whole.
1/8 of the orange juice = 1/4 liter
8/8 of the orange juice = 1/4 x 8
8/8 of the orange juice = 2 liters
There were originally 2 liters of orange juice in the container

Answer:
y = -5x + 7
Step-by-step explanation:
Since the line you are looking for is parallel to y = -5x + 4, it will have a slope of -5
Now use the point-slope form to continue
y - 2 = -5(x - 1)
y - 2 = - 5x + 5
y = -5x + 7
