Use the Commutative Property on the expression 7x - 5.

Mathematics

Answer:

Step-by-step explanation:

The Commutative Property states that the order of addition or multiplication does not matter.

EXAMPLE 1 : 1 + 2 = 2 + 1 = 3

EXAMPLE 2: 3 x 4 = 4 x 3 = 12

It appears that we cannot use the commutative property on this expression. But we can. First, we need to change - 5 = + -5.

7x - 5 = 7x + -5

Because we now have addition, we can prove the commutative property.

-5 + 7x = 7x + -5

I'm always happy to help :)

Find the value of n in each of the following proportions.

Setler79 [48]

Answer:

Step-by-step explanation:

18/n = 21/28 You can cancel, but calculators make that unnecessary. Cross multiply

21n = 18 * 28

21n = 504 Divide by 21

n = 504 / 21

n = 24

==================

12/16 = n / 64 Cross Multiply

16n = 12 * 64

16n = 768 Divide by 16

n = 768/16

n = 48

Which equation is true when x = 5? A 8x = 80 B x + 4 = 9 C 10 ÷ x = 5 D x − 6= 1

Pie

Answer:

Step-by-step explanation:

A. 8 * x = 80

8 * 5 = 40. 40 is not 80, so it doesn't work.

B. x + 4 = 9

5 + 4 = 9. This works.

C. 10 ÷ x = 5

10 ÷ 5 = 2. 5 is not 2, so it doesn't work.

D. x - 6 = 1

5 - 6 = -1. 1 is not -1, so it doesn't work.
