Answer:
777
Step-by-step explanation:
You know the total amount, 32.00, and the cost of each gallon, 1.60, so you can make an equation using x as the amount of gallons bought.
1.60x = 32.00
Now just divide 32.00 by 1.60
x= 32.00/1.60
x= 20
Answer:
120°
Step-by-step explanation:
since 60° and x are alternate interior
you get this equation
60° + x = 180
subtract 60 from both sides
x = 120
Answer:
-12
Step-by-step explanation:
Since we can subtract 12 from -2 and get -14, we might try subtracting 12.
Explanation:
Remember: we have to isolate the variable x, so that means we have to get x by itself.
Step 1:
Let’s look at our equation:
Let’s subtract 2x from both sides of the equation, since our goal is to isolate the variable. You could also subtract 6x from both sides, but you would end up with a negative number, and I find it easier to deal with positive numbers.
Step 2:
Now, let’s subtract 57 from both sides of our equation.
Step 3:
Since we have to isolate x, let’s divide both sides of the equation by 4.
Our final answer: x = 64.5
