Roxy is buying a shirt at the mall that
is priced $36. The shirt is on sale for
15% off and she will have to pay 5%
sales tax. What is the total amount
she will pay for the shirt?

$32.13

Step-by-step explanation:

                     Initial price =  $36.00

   Less  15 % = 0.15 × 36 =    -5.40

                      Sale price =  $30.60

Plus 5 % = 0.05 × 30.60 =       1.53

                  Amount paid =  $32.13

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
