Answer:
Open the bracket
then factorise
make the column with X to be the subject
therefore divide both sides by 5b which will give you
X=(5C-10)÷5b
Answer:
d
Step-by-step explanation:
Part 1)
Data:
70% milk used in a week
36 quarts of milk left
How many quarts used during the week?
Solution:
(Here we are supposed to find the milk USED, which is 70%, now we know that milk which is left is 36 quarts and it is obvious that the percentage of the milk left is 30% because 100% - 70% = 30%. )
You'll get your answer through the following equation:
(70% × 36 quarts) ÷ 30% = 84 quarts
Answer:
Therefore, the bakery used 84 quarts of milk during the week.
Part 2)
Data:
1 gallon = 4 quarts
Solution:
(Here, we're simply asked to convert the quarts of milk used during the week into gallons.)
If 1 gallon is 4 quarts, then:
84 quarts ÷ 4 = 21 gallons
Answer:
Therefore, the bakery used 21 gallons of milk during the week.
Set up a ratio of miles traveled over gallons of gas used:
We know 152 miles / 5.7 gallons.
We want to find X miles / 18 gallons
So we have:
152/5.7 = X/18
Cross multiply:
(152 x 18) = 5.7X
2736 = 5.7x
Divide both sides by 5.7:
x = 2736 / 5.7
x = 480
They can drive 480 miles.
