A mirror is 24 inches high and 28 inches wide. The center of the mirror will hang 514 feet from the floor on a wall that is 8 fe
Vanyuwa [196]

The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches

The dimension of the mirror is given as:

Height = 24\ in

Width = 28\ in

From the center of the mirror to the floor of the wall, the distance is:

Distance =5\frac14\ ft

So, the distance to the top of the mirror will be:

Top = 5\frac 14\ ft + \frac 12 \times Height

Substitute 24 for height

Top = 5\frac 14\ ft+ \frac 12 \times 24\ in

Top = 5\frac 14\ ft+ 12 \ in

Convert feet to inches

Top = 5\frac 14\times 12\ in+ 12 \ in

Top = 63\ in+ 12 \ in

Top = 75 \ in

The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.

So, we have:

Distance = 8\ ft - 75\ in

Convert feet to inches

Distance = 8\times 12\ in - 75\ in

Distance = 96\ in - 75\ in

Distance = 21\ in

Hence, the distance is 21 inches

У=-3x+3<br> y = -9x + 15
julia-pushkina [17]

Answer:

(2, - 3 )

Step-by-step explanation:

Given the 2 equations

y = - 3x + 3 → (2)

y = - 9x + 15 → (2)

Substitute y = - 3x + 3 into (2)

- 3x + 3 = - 9x + 15 ( add 9x to both sides )

6x + 3 = 15 ( subtract 3 from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (1)

y = - 3(2) + 3 = - 6 + 3 = - 3

solution is (2, - 3 )

ziro4ka [17]

Change 4 feet to inches.

You need to know that for every feet, there are 12 inches. So, if you have 4 feet, you just multiply 4 by 12 and you will get 48 inches. Note that the feet unit is larger than inches.
