David purchased these school supplies: 5 notebooks for $1.29 each 2 pens for $1.19 each 12 pencils for $0.05 each 6 erasers for $0.15 each How much change should David receive from $20?

The answer is $9.67.

Step-by-step explanation:

Notebooks: 5 * 1.29 = 6.45

Pens: 2 * 1.19 = 2.38

Pencils: 12 * 0.05 = 0.60

Erasers: 6 * 0.15 = 0.90

Total: 6.45 + 2.38 + 0.60 + 0.90 = 10.33

Change: 20 - 10.33 = 9.67

step-by-step explanation:

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'.
