Solve the equation. |k + 9| = 4

a) {-13, -5}

b) {-5, 5}

c) {-5, 13}

d) {all real numbers greater than or equal to -13 and less than or equal to -5}

A) {-13,-5}

Step-by-step explanation:

Given expression:

We need to solve for

Since lies in the absolute brackets, so we can write the solution as ()  :

For

For

Solving for K individually.

Subtracting both sides by 9.

     and

             and

So, the solution can be written as {-13,-5}

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
