We can use a system of equations in order to solve for both of the numbers. Let's start off by assigning variables to each number. The bigger number can be 'x', and the smaller number can be 'y'.

We can make two equations from the given:

x = 18 + y

("One number is 18 more than another number")

x + y = 36

("The sum of the numbers is 36")

If you look at the first equation, the variable 'x' already has a value (18 + y). We can input its value into the second equation in order to solve for y:

x + y = 36

(18 + y) + y = 36

18 + 2y = 36

2y = 18

y = 9

Input the value of 'y' into the first equation:

x = 18 + y

x = 18 + 9

x = 27

<u>One number is 27 and the other number number is 9.</u>

<u></u>

Answer:

1.  24 cubic units

2.  180 cubic units

3.  1/16 cubic units

Step-by-step explanation:

<u>Question 1</u>

Volume of a rectangular prism = width × length × height

                                                   = 3 × 4 × 2

                                                   = 12 × 2

                                                   = 24 cubic units

<u />

<u>Question 2</u>

Volume of a rectangular prism = width × length × height

                                                   = 5 × 12 × 3

                                                   = 60 × 3

                                                   = 180 cubic units

<u>Question 3</u>

Volume of a rectangular prism = width × length × height

                                                   = 1/4 × 1/2 × 1/2

                                                   = 1/8 × 1/2

                                                   = 1/16 cubic units

What is the difference of 8 times a number r and 12?
lapo4ka [179]

Answer:

The difference of 8 times a number r and 12 is solved for a number r and is given by r=\frac{3}{2}

Step-by-step explanation:

Given problem is the difference of 8 times a number r and 12

It can be written as

(8\times r)-12

To simplify the above expression :

8r-12

8r-12=0

8r-12+12=0+12 ( using addition property of equality )

8r=12

8r(\frac{1}{8})=12(\frac{1}{8}) (using division property of equality )

r=\frac{3}{2}

Therefore r=\frac{3}{2}

Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by r=\frac{3}{2}
