What is the value of a in the equation 3a + b = 54, when b = 9?

nasty-shy [4]

In order to do this you have to substitute b with 9 and get 3a+9=54, now subtract 9 from both sides to leave a by itself and get 3a=45, now divide 3 in both sides to leave a by itself and get a=15

Hope this helps

Elle is buying new flooring for her kitchen

const2013 [10]

Answer:

The total area of the two rooms is 188.25 square feet

Step-by-step explanation:

Given:

Area of the kitchen = 132 square feet.

Dimension of the Laundry room = 8 1/3 feet by 6 3/4 feet.

To Find:

The total area of the two rooms = ?

Solution:

Area of the two rooms = Area of the kitchen + Area of the laundry room

Area of the two rooms = 132 + Area of the laundry room

Area of the laundry room = $(8 \frac{1}{3}) \times (6 \frac{3}{4})$

Area of the laundry room = $\frac{25}{3} \times \frac{27}{4}$

Area of the laundry = $\frac{675}{12}$

Area of the two rooms = $132 + \frac{675}{12}$

Area of the two rooms = 132 + 56.25

Area of the two rooms = 188.25 square feet
