Question

Which steps are correct? Check all that apply.

Answer 1

Answer:

Substitute the known values into the formula:  140 = 7(w)(5).

Solve for the unknown: w = 4 m.

Check:

140 = 7(w)(5) => w = 140/(5 x 7) = 140/35 = 4. => Correct.

Substitute the known values into the formula:

7 = 140(w)(5).

Solve for the unknown: w = 7 m.

Check:

7 = 140(w)(5) => w = 7/(140 x 5) = 7/700 = 1/100. => Incorrect.

Substitute the known values into the formula:

5 = 7(w)(140).

Solve for the unknown: w = 2 m.

Check: 5 = 7(w)(140) => w = 5/(7 x 140) = 5/840 = 1/168. => Incorrect.

Hope this helps!
