For each question, choose Yes or No to tell if the expressions are equivalent. Show all work and steps. 7.4 x (12.5 - 8.4) and 7.4 x 4.1

(24 - 1.6) ÷ 3.2 and 6.4 ÷ 3.2

(7.4 + 12.5) - 8.4 and 7.4 + 4.1

8 x 2.5 - 3.2 and 20 + 4.1

1.) Yes

2.)No

3.)Yes

4.)No

Step-by-step explanation:

1.) 12.5 - 8.4 = 4.1

4.1 x 7.4 = 30.34

7.4 x 4.1 = 30.34

2.)24 - 1.6 = 22.4

22.4 / 3.2 =7

6.4 / 3.2 = 2

7 does not equal 2

3.) 7.4 + 12.5 = 19.9

19.9 - 8.4 = 11.5

7.4 + 4.1 = 11.5

11.5 = 11.5

4.)8 x 2.5 = 20

20 - 3.2 = 16.8

20 + 4.1 = 24.1

24.1 does not equal 16.8

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
