Louis must ride a mechanical lift to place 20 boxes on a high store shelf.
. louis weighs 140 pounds.
. there are x boxes that weigh 10 kilograms each and 20-x boxes that weigh 30 kilograms each.
. a kilogram is 2.2 pounds.

which expression shows the total weight, in pounds, that will be on the lift?

a.) 1,320 - 44x
b.) 1,460 - 44x
c.) 272 - 9.1x
d.) 412 - 9.1x

Step-by-step explanation:

so we have Louis who weighs 140 lbs

then we have x boxes that weigh 10 kgor (2.2 * 10) = 22 lbs

and we have (20 - x) boxes that weigh 30 kg or (2.2 * 30) = 66 lbs

140 + 22x + 66(20 - x) =

140 + 22x + 1320 - 66x =

1460 - 44x <

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

hi there!

the answer will be d: 2
