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

Answer:
22) x - 46 = 74
23) 20 portions
Step-by-step 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
Answer:
let 's' = Sara's amount
let 's-46' = Jerry's amount
equation: s - 46 = 74
s = 120
Step-by-step explanation:
2nd question: [tex]\frac{20}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex] = [tex]\frac{20}{3}[/tex]· [tex]\frac{3}{1}[/tex] = 20
