Answer:

  • The required values are 6 and 3.

Step-by-step explanation:

Let the numbers be x and y. Now, We have to follow the question's statement. First of all, we have to form equations according to the question's statement.

  • x + y = 9
  • x - y = 3

Solve the question by elimination method.

  • x + y = 9
  • x - y = 3

_______________

  • 2y = 6
  • y = 6/2
  • y = 3

<u>Put the value of y in equation 1.</u>

  • x + y = 9
  • x + 3 = 9
  • x = 9 - 3
  • x = 6

Therefore, the required values are 6 and 3.

The quotient of 4 and 1/5 will be greater than 4.
bixtya [17]
First, we will need to compute the quotient of 4 and 1/5
When we divide a number by a fraction, we convert the division to multiplication and then flip this fraction.
Therefore, in the given:
4 / (1/5) we will convert the division into multiplication and flip the 1/5 to 5
This will result is the following:
4 / (1/5) = 4*5 = 20

Comparing this quotient to 4, we will find that the quotient is greater than 4

Therefore, the given statement is: True

Phil has two rectangular prisms. The height of the second prism is 1/2 times the height of the first prism. The lengths and widt
Vesnalui [34]

The volume of the second prism is also ten times the volume of the first prism.

Let's assume that both prisms have:

width = 3 units

height = 4 units

Prism 1 length = 5 units

Prism 2 length = 50 units

Let's solve their respective volumes to compare...

Volume of prism 1 = length * width * height

                             = 5 * 3 * 4

                             = 60 units ^3

Volume of prism 2 = 50 * 3 * 4

                             = 600 units ^3

Prism 2/ prism 1 = 10

That means prism 2 is ten times the volume of prism 1.
