Answer:
B
Step-by-step explanation:
1/2(5-7x)=8-4x+6
-7/2x+5/2=-4x+14 Simplify both sides
1/2x+5/2=14 Add 4x to both sides
1/2x=23/3 Subtract 5/2 on both sides
2*(1/2x)=2*(23/2) Multiply both sides by 2
x=23 - Final Answer

Answer:
All have a rate of change of 4.
Step-by-step explanation:
To simplify some things, we're going to be dividing by 10 because that's the separation between each answer. (40-50, 50-60, 60-70, yadda yadda yadda)
From 40 to 50 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 0 and 40 is 40.
From 50 to 60 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 40 and 80 is 40.
From 60 to 70 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 80 and 120 is 40.
From 70 to 80 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 120 and 160 is 40
From 80 to 90 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 0 and 160 is 200

Answer:
96 square tiles are needed
Step-by-step explanation:
To calculate this, the first thing we need to do is calculate the total area covered by the rectangular wall.
Mathematically, the area of the rectangle = 16 * 24 = 384 ft^2
The next thing we need to do is calculate the area of the square tiles = L^2 = 2^2 = 4 ft^2
the number of square tiles needed = Area of rectangular wall/Area of square tiles = 384/4 = 96
