The sum of two numbers is 31.5. the difference is 5.25. find the numbers

The two numbers are 18.375 and 13.125

Step-by-step explanation:

Given that the sum of two numbers is 31.5 and their difference is 5.25

we have to find the two numbers.

Let the two numbers are x and y.

As sum of two numbers is 31.5 and difference is 5.25

∴   →   (1)

  →   (2)

Adding eq (1) and (2), we get

(2) ⇒ 18.375-y=5.25 ⇒ y=13.125

Hence, the two numbers are 18.375 and 13.125

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
