Solve for X<br> -3(x - 2) = 4(x + 1)
lesya [120]

Answer:

The answer for this is.. x= 5/3 the decimal is x=1.66666..

Step-by-step explanation:

Expand -3(x-2) : -3x+6

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

Add similar elements: x-3x= -2x

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

Expand 4(x-1): 4x-4

-2x+6= 4x-4

Subtract 6 from both sides

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

Simplify

-2x-4x-10

Subtract 4x from both sides

-2x-4x=4x-10-4x

Simplify

-6x=-10

-6x/-6 = -10/-6

so the answer is x-5/3

A schools enrollment in 2012 was 1234 now it is 1456 what does the expression look like that would help me find the percent chan
astraxan [27]

Answer:

.18 % increase

Step-by-step explanation:

First you would find what the difference is between the school enrollment

you would do 1456 - 1234 =  222

Then you would divide 1234/1456 = 84.75% to see the total percentage

The increase however has a percentage of .18%

To check your work you would do .18 x 1234 = 222.12 ( round to the nearest whole number so it would just be 222) then add 1234+ 222 = 1456!
