Question

Anyone know this two questions I can't figure this out

Answer 1

let 's' = Sara's amount

let 's-46' = Jerry's amount

equation: s - 46 = 74

s = 120

Explanation:

2nd question:
`(20)/(3)` ÷
`(1)/(3)` =
`(20)/(3)`·
`(3)/(1)` = 20

Answer 2

22) x - 46 = 74

23) 20 portions

Explanation:

21)

Let x = the number of cars Sara sold.

Jerry sold 46 cars fewer than Sara, so Jerry sold x - 46 cars.

Jerry sold 74 cars, so the equation is

x - 46 = 74

Answer: x - 46 = 74

22)

Let the number of 1/3 lb portions = x

The weight of x number of 1/3-lb portions is 1/3 * x, or simply x/3.

The full bag weighs 6 2/3 lb.

The equation is

x/3 = 6 2/3

Now we solve for x.

x/3 = 20/3

Multiply both sides by 3.

x = 20

Answer: 20 portions
