Tim used the steps shown to find the value of the expression 3,912 ÷ 12: Step 1. There are 300 12s in 3,912 Step 2. 3,912 − 3,600 = 312 Step 3. There are 20 12s in 312 Step 4. 312 − 240 = 72 Step 5. There are 6 12s in 72 Step 6. Quotient = 300 + 20 = 320 In which step did Tim first make an error?

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

answer: plz put a pic in so i can answer it

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
