Explain how to find 40 times 80 using mental math

Answers

Using mental math's, the product of 40 times 80 is: 120

How to find the product of numbers?

We want to find the number product given as:

40 times 80

Now, this can be expressed as:

40 * 80

This means a product or multiplication of 40 and 80.

We can break the numbers down as:

40 = 4 * 10

80 = 8 * 10

Thus, we have:

(4 * 10) + (8 * 10)

= 10(4 + 8)

= 10 * 12

= 120

7. Use the Division Property of Equality to complete the following statement. (1 point)If 5x = 2y, then x = ?
OO
UOD
W
O2y - 5

Please help

Answers

For this case we have the following equation:

5x = 2y

To find the value of "x", we use the division equality property, that is, we divide by 5 on both sides of the equation:

\frac {5x} {5} = \frac {2y} {5}\nx = \frac {2} {5} y

Thus, using the mentioned property we have to: x = \frac {2} {5}y

Answer:

x = \frac {2} {5} y
