Step-by-step explanation:

Let the numbers be x and y

The sum of the two numbers is 56 :

Step 1:

X + Y = 56.......... (1)

Also, the first number is 2 times greater than the second number:

Step 2:

2X + Y = 0........... (2)

By substitution method, make Y the subject from (2)

Step 3:

Y = -2X .......... (3)

Put (3) into (1)

Step 4

X - 2X = 56

-X = 56

\frac{ - x}{ - 1}  =  \frac{56}{ - 1}

X = -56

Put X=56 into (3)

Step 5

y =  - 2( - 56)

y = 112

The second number is now 112.

Answer:

y = 56/3

Step-by-step explanation:

We need to write equations to solve

Let the two numbers be x and y

The sum is 56

x+y = 56

The first number is 2 times greater than the second number.

x = 2*y

Substitute this into the first equation

x+y = 56

2y+y=56

3y = 56

y = 56/3

Kenny buys 4 1liter bottles of water how many millileters of water does Kenny buy
kenny6666 [7]
Kenny bought 4 1liter bottles of water

1liter is equal to 1,000 milliliters (milli means 1,000)

What that means is that in each bottle of water that he purchased, he has 1,000 milliliters

He has 4 bottles, so we simply take

4(bottles) x 1,000(amount of water in each bottle)

4 x 1,000 = 4,000 milliliters

four friends shared 5 sandwiches after their hike. if they each ate an equal share, how many sandwiches did each friend eat?
adelina 88 [10]
You would do 5 divided by 4

the question is tells us that the sandwiches are being shared equally so it is the total amount. it is being distributed to 4 friends meaning it is being divided by 4.

5 divided by 4 = 1.25

they all got 1.25 of the sandwiches
