Question

Responses

42 + x = 21.43; $21.50

21.43 + x = 42; x = $20.57

21.43 + x = 42; $17.75

42 + x = 21.43; x= $21.00

Answer 1

Let x represent the amount of money Ally received for cleaning the attic.

The equation to represent the problem is 21.43 + x = 42.

Solving for x, we subtract 21.43 from both sides of the equation:

x = 42 - 21.43 = 20.57

Therefore, Ally received $20.57 for cleaning the attic.

How many packages of diapers can you buy with $45 if one package costs $9? Write an equation for the problem and solve.(1 point)
Responses

9d=45; 5 packages of diapers

45d=9; You can't buy a whole package.

9d=45; 9 packages of diapers

45d=9; 5 packages of diapers

Answer 3

Let d represent the number of packages of diapers.

The equation to represent the problem is 9d = 45.

Solving for d, we divide both sides of the equation by 9:

d = 45/9 = 5

Therefore, you can buy 5 packages of diapers with $45.

You have a certain number of snacks you want to hand out to your friends. If you give each of your 7 friends 11 snacks, how many snacks did you have originally? Write an equation for this problem and solve.(1 point)
Responses

117=x
; 77 snacks
11 sevenths is equal to x; 77 snacks

x7=11
; 77 snacks
x over 7 is equal to 11; 77 snacks

117=x
; 18 snacks
11 sevenths is equal to x; 18 snacks

x7=11
; 4 snacks
x over 7 is equal to 11; 4 snacks

Answer 5

Let x represent the number of snacks you originally had.

The equation to represent the problem is 7 * 11 = x.

Solving for x, we multiply 7 by 11:

x = 7 * 11 = 77

Therefore, you originally had 77 snacks.
