Stephanie spent half her weekly allowance at the movies. To earn more money, her parents let her clean the gutters for $4.00. What is her weekly allowance if she end with $13.00?

$18

Step-by-step explanation:

If weekly allowance is x

Half of it is x/2

Remaining half plus $4 is $13

x/2 + 4 = 13

Subtract by 4 both sides

x/2+4-4 = 13 - 4

x/2 = 9

Multiply both sides by 2

(x/2)*2 = 9*2

x = 18

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
