Solve the equation using the distributive property and properties of equality. -5(a+3)=-55
What is the value of a?
1. -14
2. 8
3. 14

a=8

Step-by-step explanation:

-5(a+3)=-55

So we multiply -5 times a and 3 so we get:

-5a-15=-55

+15      +15

-

-5a=-40

÷-5    ÷-5

a=8

Hope this helped :D

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)
