Answer:
The first option.
Because we're solving for the price of each gallon, x will represent the cost of each gallon. Since 8.4 is the total amount of gallons, multiply 8.4 and x to get $23.94. Solve for x by dividing 23.94 to get $2.85 per gallon. To check this, substitute 2.85 for x into the equation: 8.4 (2.85) = 23.94
Answer:
Step-by-step explanation:
To better understand the question we need to properly format the expression
as we can see we have three brackets, we can proceed by first opening the first two brackets, we have.
we then continue by collecting like terms
we then solve for the remaining two brackets
we then continue by collecting like terms
from the two brackets we obtained each, we now have to multiply both terms together and solve we have
collecting and summing all like terms we have
Start by putting whole numbers together and fractions together;
5-2 + 2/7-5/7
3+(-3/7)
=3-3/7
=21/7-3/7
=18/7
=2
