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.

7/9=14/18. 5/6=15/18

7/9 <. 5/6

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

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.

2L + 2W = 48

L + W = 24

(W + 7) + W = 24

W = 8.5 inches

L = 15.5 inches

Answer:

x = 9/2x = 5

Step-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

Write an equation in slope intercept form for the line with slope - 3/4 and y-intercept -2. Then graph the line.
​

Answers

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).

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]
