So we have W/-1.3 (w over -1.3) then = -6.2
It would look like: W/-1.3 = -6.2
Put -6.2 over 1 so it looks like W/-1.3 = -6.2/1
Then cross multiply so W x 1 is W
-6.2 times -1.3 is 8.06
Therefore, W is 8.06
Answer:
18
Step-by-step explanation:
95 divided by 5 equals 19
19-1=18
Note the equal sign. What you do to one side, you do to the other.
Also, remember to do the opposite of PEMDAS.
First, subtract 6 from both sides
-2x + 6 (-6) = -20 (-6)
-2x = -26
Next, isolate the x. Divide -2 from both sides
(-2x)/-2 = (-26)/-2
x = -26/-2
x = 13
13, or (B) is your answer

We will caluclate the cost per gallon first. Then, we will multiply the new quantity by this cost, so we get the new cost.
As we are told that 6 gallons costs 26.58, we can divide 26.58 by 6 to calculate the cost per gallon. It would be
Now we multiply this quantity by 18, so we get the cost of 18 gallons. It would be
so the cost of 18 gallons is 79.74
