18) Value of b is : $b\geq 8$

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

$12b-46\geq 50$

Solving to find the value of b:

$12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq 8$

So value of b is : $b\geq 8$

Option A is correct.

19) We need to find the correct graph of the equation:

$4y-2$

Solving:

$4y-2$

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.

You go to Home Depot to buy some materials for a project. Your total bill for materials only was $45.90. You go to the check out

IrinaVladis [17]

Answer:

$34.20

Step-by-step explanation:

First, find the cost with tax

You are paying 7.2% tax, but you are also paying for 100% of the bill

100%+7.2%=107.2%

So, you are really paying for 107.2% of the bill

Convert 107.2% to a decimal by dividing by 100 or moving the decimal 2 spaces to the right

107.2/100=1.072

Multiply the decimal by the cost of the bill

1.072*45.90=49.2048

But, we also have a coupon for $15 off

Subtract 15 from the cost with tax

49.2048-15=34.2048

Round to the nearest cent/hundreth

$34.20

Hope this helps! :)
