Answer:

3a:2b=6:1  

Step-by-step explanation:

given, \frac{a+b}{a-b}=\frac{5}{3}

    3(a+b)=5(a-b)

3a+3b=5a-5b

2a=8b

a=4b

3a:2b=3(4b):2b=12b:2b=6:1

hence 3a:2b=6:1  answer

Answer:

3 a : 2 b = 6 : 1

Step-by-step explanation:

<em>\frac{a + b}{a - b} = \frac{5}{3}</em>

<em>3 ( a + b) = 5 ( a - b) </em>

<em>3 a + 3 b = 5 a - 5 b </em>

<em>5 b + 3 b = 5 a - 3 a </em>

<em> 8 b = 2 a </em>

<em> 2 a = 8 b</em>

<em><u>a = 4 b</u></em>

<em>3 a = 3 × 4 b</em>

<em><u>3 a = 12 b</u></em>

<em>3 a: 2 b = 12 b : 2 b</em>

<em>3 a : 2 b = 6 : 1</em>

The following list shows how many brothers and sisters some students have:
Goryan [66]

Answer:

5

Step-by-step explanation:

So we have the set of numbers: 3,4,4,5,5,2,5,4,6,3,6,5,3.

Mode just means the most repeated number so let's sort them into groups.

(2) (3,3,3) (4,4,4) (5,5,5,5) (6,6).

the most repeated number is 5 which we see in the sequence about 4 times.

Kinu has 7 memory sticks that contain data from his computer. Some of the me
ra1l [238]

Solving the system of equations, it is found that x = 3, that is, there are 3 128 MB memory sticks.

--------------------

We want to solve for x, thus, in the first equation, we write y as a function of x, that is:

y = 7 - x

Replacing in the second equation:

128x + 512(7 - x) = 2432

128x + 3584 - 512x = 2432

384x = 1152

x = \frac{1152}{384}

x = 3

x = 3, that is, there are 3 128 MB memory sticks.
