What value of x makes the equation -6x-20=-2x+4 (1-3×) true​
dmitriy555 [2]

Answer:

x = 3

Step-by-step explanation:

-6x - 20 = -2x + 4 (1 - 3x)

Distributive property

-6x - 20 = -2x + 4  - 12x

Combine like terms

-6x - 20 = -14x + 4  

Add 14x to both sides

-6x - 20 + 14x = -14x + 4  + 14x

Simplifying

8x - 20 = 4

Add 20 to both sides

8x = 24

Divide both sides by 8

x = 3

The average 10 year old boy is 55 inches tall. How tall is this, in feet?
Elena L [17]
There is 12 inches in a foot. Times inches by feet. You can pick a number for the feet and do trial and error until you get a number the closet to 55.

12 inches times 4 feet equals 48 inches.
12x4= 48
Now subtract 55 inches from 48 inches
55-48= 7 inches

So 4 feet and 7 inches tall
