Step-by-step explanation:
Consider the rule y = 5x + 7.
a. How many tiles are in Figure 0?
In figure 0, we let x=0
y = 5*0+7 = 0+7 = 7
b. Which figure has 37 tiles?
This means y = 37
37 = 5x+7
Subtract 7 from each side
37-7 = 5x+7-7
30 = 5x
Divide by 5
30/5 = 5x/5
6 =x
Figure 6 has 37 tiles
c. In the equation y = mx + b, what do the letters m and b represent?
m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0

Step-by-step explanation:
If the number of types of massages is represented by 4x + 3 and the number of types of manicures is represented by -6x + 5 and the number of types of pedicures is represented by 8x - 7, what is the expression for the total number of services they have to choose from?
2,3,7,and 5 are the factors
Circumference = PI * diameter
diameter = Circumference / PI
diameter = 40.82 / 3.14159265
diameter =

Basically, the rug is roughly 1 foot wider than the room.
So.. hmm notice the picture here
we know the length is 59 more than twice the width,
twice the width, 2 * w, or 2w
59 more than that
2w + 59
we also know that, whatever that is, the diagonal of it is,
2 more inches than that, or
(2w + 59) + 2
now.. use the pythagorean theorem

you'd end up with a quadratic, after simplifying, solve for "w"
