Add the fractions and simplify the answer: 1/2 + 2/3

Answers

The simplification of the fraction would be; 7/6.

What is a fraction?

A fraction represents a part of a number or any number of equal parts. There is a fraction, containing numerator(upper value) and denominator(lower value).

Therefore, first convert the denominator (bottom n umber) to the same number.

1/2 and 2/3 then the numbers are 2 and 3

the least common multiple is 6

To convert is multiply each by bottom number of the other over the other;

1/2 +2/3

1/2 x 3/3 + 2/3 x 2/2

3/6 + 4/6

(7)/6

7/6

Hence, the simplification of the fraction would be; 7/6.

Enter the value of p so the expression 5/6 - 1/3n equivalent to p(5-2n)

Answers

You said 5/6 - 1/3 n = p (5 - 2n)

Divide each side by (5 - 2n) :

   p = (5/6 - 1/3 n) / (5 - 2n) .

That's about all you can do with it.
As you can see, the required value for 'p'
depends on the value of 'n'.

If you want to get rid of those awkward fractions,
I guess you could multiply top and bottom by 6 .
Then you have ...

   p = (5 - 2 n) / 6·(5 - 2n) .

Oh, my goodness ! Look at that !

   p = 1/6 .

It doesn't even depend on 'n' at all. It's always true,
no matter what 'n' is.

I am surprised.

Answer:

Step-by-step explanation:

Let x

Then we have 15 (x + 9) = 420.

We can divide both side by 15, getting x + 9 = 28. Then, we can subtract both sides by 9, getting x = 28 - 9 = 19.

Since there are 15 players and he bought a basketball for each of them, he bought 15 basketballs in total.The price of a basketball costs $9.The total price of all 15 basketballs = $9 * 15 = $135.He spent $420 on uniforms and basketballs, and he spent $135 on basketballs.Thus, he spent $420 - $135 = $285 on uniforms.As he bought a uniform for each of the 15 players, he bought 15 uniforms in total.The price of 15 uniforms is $285.The price of 1 uniform is $285 ÷ 15 = $19.

Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)

Answers

Neighborhood A: 30 homes. Each year increases by 20%.
Neighborhood B: 45 homes. Each year increases by 3.

A: 30(1.20)^x
B: 45 + 3x

A: 30(1.20)^5 = 30(2.48832) = 74.6496 or 75 houses
B: 45 + 3(5) = 45 + 15 = 60 houses
