8 0

Step-by-step explanation:

2/3 lost is 1/3 kept

2/3 of the 1/3 kept is 2/9 lost

1/3 x - 2/9 x = 4

3/9 x - 2/9 x = 4

1/9 x = 4

x = 36

First she lost 2/3 of 36, which is 24. She had 12 left. Then she lost 2/3 of 12 which is 8. She had 4 left.

never [62]

Answer:

552

Step-by-step explanation:

23x + 4y when x=20 and y=23

if x=20 and y=23 all you have to do is replace the numbers and solve

23(20) + 4(23)

Multiply 23*20 which is equal to 460

Then you multiply 4*23 which is equal to 92

The problem is now 460 + 92

add it, and you get 552.

Hope this helps!!

How does this work? Answers please!
Elena L [17]

Answer:

The surface area is 91

Step-by-step explanation:

3*4=12

12/2=6

        6*2=12

        7*5=30

        4*7=28

        3*7=21

12+30+28+21=91

The equations that are on the left are caculations triangle calcuations. The equations on the right are the ones that equal each of the 2d shapes in the prism and if u add them all up you get your surface area.
