The perimeter of a rectangle is 48 inches. If the length is 2 more than the width, what is the length and width?
Only an algebraic solution is accepted
Answers:
Length = 13 inches
Width = 11 inches
=====================================================
Work Shown:
w = width, some positive number
w+2 = length, since it is 2 inches more than the width
P = perimeter of the rectangle
P = 2(width + length)
P = 2(w + w+2)
P = 2(2w+2)
P = 4w+4
We're told that the perimeter is 48 inches. So we'll set the previous result equal to 48 and solve for w.
P = 48
4w+4 = 48
4w = 48-4
4w = 44
w = 44/4
w = 11
The width is 11 inches.
w+2 = 11+2 = 13
The length is 13 inches.
----------------
Checking the answers:
P = 2(L+W)
P = 2(13+11)
P = 2(24)
P = 48
The answers are confirmed.

Carla reads 36 pages in 3 hours. At this
rate, how long will it take Carla to read a
book with 180 pages?
Answer:
It will take 15 hours to read a book with 180 pages
Step-by-step explanation:
First, let's set up a ratio to find how many pages she reads per hour:
36:3 = 12:1
Now we can set up fractions to solve:
[tex]\frac{12}{1} =\frac{180}{x}[/tex]
Cross multiply:
[tex]12x=180[/tex]
Divide each side by 12:
[tex]x=15[/tex]

Step-by-step explanation:
The graph of a line with negative slope goes down to the right. The line would still go through the origin. An example is attached.
An appliance store decreases the price of a 19 inch television set 21% to a sale price of $475.19. What was the original price
Answer:
The original price of the TV was $609.51
Step-by-step explanation:
100% - 21% = 79%
Now the question were really asking here is "475.19 is 79% of what?"
475.19 = 0.79 * x
To get x we must take 475.19 and divide by 0.79, which is about 601.51
The original price of the TV was $609.51

How many kilometers per minute 26.5 miles in 2.65 hours is
Answer:
Step-by-step explanation:2.25 miles per hour = 3.621 kilometers per hour
Formula: multiply the value in miles per hour by the conversion factor '1.609344'.
So, 2.25 miles per hour = 2.25 × 1.609344 = 3.621024 kilometers per hour.

7/9 < 5/6
We find the LCM of 9 and 6 which is 18.
For the first fraction, 6 multiplied by 3 is 18 so we multiply both the numerator and denominator by 3 to get:
5/6 = 5*3/6*3 = 15/18
For the second fraction, 9 multiplied by 2 is 18 so we multiply both the numerator and denominator by 2 to get:
7/9 = 7*2/9*2 = 14/18
We can see that 5/6 is greater than 7/9.

Write an equation in slope intercept form for the line with slope - 3/4 and y-intercept -2. Then graph the line.
Answer:
y = (-3/4)x - 2
Step-by-step explanation:
Start with the slope-intercept form y = mx + b. Replace m with -3/4 and y with -2. We then have y = (-3/4)x - 2.
Graphing this line: Knowing that b = -2, plot the point (0, -2). Find the x-intercept by letting y = 0 in the above equation and solving for x:
0 = (-3/4)x - 2, or (3/4)x = -2, or x = (4/3)(-2), or x = -8/3. Plot this x-intercept (-8/3, 0). Finally, draw a line through the points (0, -2) and (-8/3, 0).

Answer:
x = 9/2x = 5Step-by-step explanation:
1. Substitute for k(x) and solve.
k(x) = 6x -12
15 = 6x -12 . . . . substitute for k(x)
27 = 6x . . . . . . add 12
27/6 = x = 9/2 = 4 1/2 . . . . . divide by 6

2. Find f(x) = 7 on the vertical scale. Follow that horizontal line over to the graph. Follow the vertical line at that intersection down to the x-axis. It will be halfway between the lines marked 4 and 6. That is, the x-value is 5.
f(x) = 7 = f(5)
x = 5
