Which TWO number sentences could be used to find the total number of boxes Elizabeth will need?

Responses

(24÷4)+(20÷4)

(40÷4)+(8÷4)

(40×4)+(8×4)

(24÷4)+(24÷4)

48 x 4

Answer 1

(40÷4)+(8÷4)

(24÷4)+(24÷4)

Explanation:

1 box holds —> 4 cup cakes

x boxes holds —> 48 cup cakes

cross multiply

48 × 1 = 4 × x

48 = 4x

`( \\ 48)/(4) = (4x)/(4)`

x = 12

since the number of boxes needed to hold 48 cup cakes are 12 we need to look for an expression that is equivalent with our figure.

lets try

(24 ÷ 4) + (20 ÷ 4)

= 6 + 5

= 11 (Not correct)

(40 ÷ 4) + ( 8 ÷ 4)

= 10 + 2

= 12 ( correct)

(40 × 4) + ( 8 × 4)

= 160 + 32

= 192(Not correct)

(24 ÷ 4) + (24 ÷ 4)

= 6 + 6

= 12(correct)

48 × 4

= 192(Not correct)

i hope i helped
