Answer:

all real numbers

Step-by-step explanation:

3x-8 = -x + 4(x-2)

distributive property:

3x - 8 = -x + 4x-8

Combine like terms:

(add 3x to both sides)

-8 = -8

That means that x can be any number, because in the end, x will be canceled out from the equation.

15 1/4 acres of land are divided into lots of at least 2/3 acres each. What is the maximum number of lots that can be created
alex41 [277]
We know that
15 1/4 acres-----------> (15*4+1)/4-----> 61/4 acres

[<span>number of lots]=(61/4)/(2/3)----> (61*3)/(4*2)---> 183/8----> 22.875 
22.785-----> 22 7/8

we know that
7/8--------> multiply by 3-------> 21/24
2/3-------> multiply by 8-------> 16/24
21/24-16/24-------> 5/24
so
22 7/8 is equals to--------> 22 21/24----> 22 (16/24+5/24)

t</span><span>he maximum number of lots that can be created are 22+1-----> 23 lots
</span><span>and there is a remnant of 5/24</span>

SOVA2 [1]

Answer:

x = -1/8

Step-by-step explanation:

to determine the value of x in the expression-6=3/4x

first, cross multiply inorder to have a straight line equation ,then combine the like terms together and evaluate.

solution

-6=3/4x

using cross multiplication techique

4x × -6 = 3

-24x = 3

divide both sides by the coefficient of x which is -24

-24x/-24 = 3 /-24

x = -1/8
