How do i solve this?

To solve this problem, we first have to combine the two fractions on the left side of the equation.  To do this, we must make a common denominator of 8.  Because 8/8 is equal to 1, we can substitute this value into the equation:

3x/8 - 8/8 = 5/8

Next, we can subtract the fractions on the left side of the equation to simplify.  Remember that if fractions have the same denominator, we simply subtract their numerators and keep the difference over the common denominator.

3x - 8/8 = 5/8

Since both sides of the equation have a denominator of 8, we can cancel out this denominator on both sides by multiplying both sides by 8.  This gives us:

3x - 8 = 5

Next, we should add 8 to both sides of the equation so that we can get all of the constants to the right side of the equation.

3x = 13

Finally, we should divide both sides by 3 to get the variable alone on the left side of the equation.

x = 13/3

Therefore, your answer is x = 13/3.

Hope this helps!

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8
