Answer:

The 2 numbers are 14 and 17.

Step-by-step explanation:

Let the 2 numbers be x and y.

x + 11 = 2y

x - 2y = -11...............A

y +20 = 2x

2x - y = 20 ...............B

Multiply equation A by -2:

-2x + 4y = 22............C

Adding B and C :-

3y = 42

y = 14.

Substitute y = 14 in equation A:

x - 2(14) = -11

x = -11 + 28

x = 17.

Solve -7(s+2)-12=37<br> What is s
Shkiper50 [21]

Answer:

<em>s= </em>-5.57 (rounded to the nearest hundredth)

Step-by-step explanation:

1. Multiply s and 2 by 7.

You'll get -7s-14. We'll come back to this later

2. Subtract 12 from 37.

You'll get 25

3. Add 14 to both sides so that you cancel out the -14.

The equation stands as -7s= 39

4. Divide both sides by -7 so that we leave <em>s </em>by itself.

s= -5.57142857

Sarah had 25 candies. Sarah gave 25 of the candies to her sister. Of the amount left, she gave 2/3 to her friend. How many candi
RoseWind [281]

Answer:

She has 5 candles left.

Step-by-step explanation:

Total of candy Sarah has = 25candies

If Sarah gave 2/5 of the candies to her sister, the total amount she gave her sister will be 2/5 of 25

2/5 of 25 = 10

The remaining candy left will be 25-10 which is 15.

If she gave 2/3 of the amount left to her friend, the amount she gave her friend will be 2/3×15 = 10candies.
