Answer:
90-90.000 or 90-100
Step-by-step explanation:
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:
From the center of the mirror to the floor of the wall, the distance is:
So, the distance to the top of the mirror will be:
Substitute 24 for height
Convert feet to inches
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:
Convert feet to inches
Hence, the distance is 21 inches

2x - 3y = -24
x+ 6y = 18
you solve the first one by the x:
2x = -24 + 3y
x = (-24+3y)/2
then you substitute what you found in the other equation and you solve by y
(-24+3y)/2 + 6y = 18 multiply everything by 2
-24 + 3y + 12y = 36
3y + 12y = 36 + 24
15y = 60
y = 60/15
y = 4
Good job! You found your y! :D
Now let's substitute the y in the first equation with 4:
2x - 3(4) = -24
2x - 12 = -24
2x = -24 + 12
2x = -12
x = -12/2
x= -6
Done!! ;) <span />
Fist subtract 5 from both sides
Equation is now 2s is greater than or equal to 44
Now divide by 2
Equation is now s is less than or equal to 22
Be sure to flip equality sign when dividing
4(-3) + 3(-5) + 7
-12+-15+7=-20
