2.8667

Step-by-step explanation:

I'm going to try and show my work on here, but it is difficult without a graph or excel spreadsheet:

Class        Grade          Credit        Points

Math            C                  5               5*2=10  

Soc              B                  3               3*3=9

Eng              B                  4               4*3=12

Music           A                 3                3*4=12              

Total                               15               10+9+12+12=43

To get the totals I added up everything from each column.

To find the GPA, you Divide the Total Points = 43 by Total Credits = 15

43/15 = 2.8667

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
