What is 3/2n-8/3=29/12

Mathematics
1 answer:
bixtya [17]3 years ago
5 0

Simplify 3/2n to 3n/2

3n/2 - 8/3 = 29/12

Add 8/3 to both sides

3n/2 = 29/12 + 8/3

Simplify 29/12 + 8/3 to 61/12

3n/2 = 61/12

Multiply both sides by 2

3n = 61/12 × 2

Simplify 61/12 × 2 to 122/12

3n = 61/6

Divide both sides by 3

n = 61/6/3

Simplify 61/6/3 to 61/6 × 3

n = 61/6 × 3

Simplify 6 × 3 to 18

<u>n = 61/18</u>

Write an example of the associative property of addition
vfiekz [6]
The word "associative" comes from "associate" or "group";the Associative Property is the rule that refers to grouping. For addition, the rule is "<span>a + (b + c) = (a + b) + c</span><span>"; in numbers, this means 
</span>2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is "<span>a(bc) = (ab)c</span>"; in numbers, this means2(3×4) = (2×3)4<span>. Any time they refer to the Associative Property, they want you to regroup things; any time a computation depends on things being regrouped, they want you to say that the computation uses the Associative Property.</span>

Find the midpoint of the line segment joining the points (-3,-2) and (-7,5)
Mumz [18]

Answer:

The midpoint is (-5,1.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

( -3+-7)/2 = -10/2 = -5

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

( -2+5)/2 = 3/2 = 1.5

The midpoint is (-5,1.5)

Please help me if you know this​
lisabon 2012 [21]
First you have to subtract 1.3 from 0.75 which equals -0.55. Then you have to add 3/7 to 2 which equals 2 and 3/7. Then you divide 2 and 3/7 by -0.55 which equals 0.9785 and that’s your answer. Sorry I don’t know the answer for the second problem but I hope this helped.

(x+1)-6(x+1)+8 how to factorise it?<br>​
sergij07 [2.7K]

Answer:

Step-by-step explanation:

If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.

x + 1 + 6x + 6 + 8

7x + 15 is your final answer.

However, I think the question is

(x + 1)^2 + 6(x + 1) + 8

Let y = x + 1

y^2 + 6y + 8

(y + 2)(y + 4)

(x + 1 + 2 ) ( x + 1 + 4)

(x + 3)(x + 5)
