So you wanna take the total of $325 and subtract the original fee of $26 so you have $299. You take the $299 and divide it by 13. That gives you $23, your answer is 23.

Rewrite 2 5/8 with a denominator of 24

gladu [14]

Answer:

63/24

Step-by-step explanation:

First you change the whole 2 to have a fraction of 48/24.

Next you have change 5/8 so its denominator has a 24. So you multiple the 8 by 3 to get 5/24. But then you have to multiply the 5 by 3 also so it is still the same fraction just bigger and you get 15/24. Now add the 15/24 with 48/24 to get 63/24.

Hope this helps!

The length of a rectangle is 20 meters and the width is 4 meters. What is the perimeter of the rectangle? Do not include units i

alina1380 [7]

Answer:

$\boxed {\boxed {\sf 48 \ meters }}$

Step-by-step explanation:

The perimeter is the sum of the side lengths.

A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is

$p= 2l+2w$

The length is 20 meters and the width is 4 meters.

$p= 2(20 \ m )+ 2(4 \ m )$

Multiply.

$p= 40 \ m + 8 \ m$

Add.

$p= 48 m$

The perimeter of the rectangle is <u>48 meters. </u>

Multiply both equations by a constant

tiny-mole [99]

Answer:

(- $\frac{1}{3}$ , $\frac{3}{4}$ )

Step-by-step explanation:

9x + 8y = 3 → (1)

6x - 12y = - 11 → (2)

Multiplying (1) by 12 and (2) by 8 and adding will eliminate the y- term

108x + 96y = 36 → (3)

48x - 96y = - 88 → (4)

Add (3) and (4) term by term to eliminate y

156x = - 52 ( divide both sides by 156 )

x = $\frac{-52}{156}$ = - $\frac{1}{3}$

Substitute this value into either of the 2 equations and solve for y

Substituting into (1)

9(- $\frac{1}{3}$ ) + 8y = 3

- 3 + 8y = 3 ( add 3 to both sides )

8y = 6 ( divide both sides by 8 )

y = $\frac{6}{8}$ = $\frac{3}{4}$

solution is (- $\frac{1}{3}$ , $\frac{3}{4}$ )

Devide 60 in the ratio of 2:3

nevsk [136]

Answer:

Let the amounts be 2x and 3x.

Then 2x+3x=60

So, 5x=60

So, x=60/5=12

So, amounts are

2x=2*12=24

And 3x=3*12=36

Hope this helps you!
