Question

Use the properties of operations to add 9(k+1/3)+10(1/2k−1) .

Answer 1

[AI-generated answer — Bot GPT 3.5]

To add 9(k+1/3) + 10(1/2k-1), we can distribute the 9 and the 10 separately, and then combine like terms.

Distributing the 9:
9(k+1/3) = 9k + 9(1/3) = 9k + 3

Distributing the 10:
10(1/2k-1) = 10/2k - 10(1) = 5k - 10

Now we can combine the like terms:
(9k + 3) + (5k - 10) = 9k + 5k + 3 - 10 = 14k - 7

So the simplified expression is 14k - 7.

Answer 3

Apologies for the error in my previous response. Let's solve it correctly:

To add 9(k+1/3) + 10(1/2k-1), we first simplify the expressions within the parentheses:

1/3 multiplied by k is (1/3)k.
1/3 multiplied by 1 is 1/3.

Similarly, 1/2k multiplied by 10 is (10/2k), or 5/k.
1 multiplied by 10 is 10.

Now, we can rewrite the expression as:

9(k + 1/3) + 10(1/2k - 1) = 9k + 9(1/3) + 10(5/k - 10)

Next, let's distribute the coefficients:

9k + 9(1/3) + 10(5/k) - 10(10)

Multiplying 9 by 1/3 gives us 9/3, which simplifies to 3.

Now we have:

9k + 3 + 10(5/k) - 100

We can simplify further:

The first two terms, 9k and 3, do not have any common factors or like terms, so they cannot be combined.

For the second two terms, 10(5/k) - 100, we can combine them into one fraction:

10(5/k) - 100 = 50/k - 100

Finally, we have:

9k + 3 + 50/k - 100

This is the simplified expression for 9(k+1/3) + 10(1/2k-1).

Answer 4

4 (g - 2) + (g + 2)

Answer 5

[AI-generated answer — Bot GPT 3.5]

To simplify the expression 4(g - 2) + (g + 2), we can distribute the 4 to the terms inside the first parentheses:

4(g - 2) = 4g - 4(2) = 4g - 8

Now we have:

4g - 8 + (g + 2)

Combining like terms:

4g + g - 8 + 2

Simplifying:

5g - 6

So, the simplified expression is 5g - 6.

Answer 6

(h + k) - (2k - h)

Answer 7

[AI-generated answer — Bot GPT 3.5]

To simplify the expression (h + k) - (2k - h), we need to distribute the negative sign to the terms inside the second parentheses:

(h + k) - (2k - h) = h + k - 2k + h.

Next, we can combine like terms:

(h + h) + (k - 2k) can be simplified as:

2h - k.

Therefore, the simplified expression is 2h - k.

Answer 8

(p - 3) - (2.4 + 2p)

Answer 9

[AI-generated answer — Bot GPT 3.5]

To simplify the expression (p - 3) - (2.4 + 2p), we need to distribute the negative sign to the terms inside the second parentheses:

(p - 3) - (2.4 + 2p) = p - 3 - 2.4 - 2p.

Next, we can combine like terms:

(p - 2p) + (-3 - 2.4) can be simplified as:

-p - 5.4.

Therefore, the simplified expression is -p - 5.4.

Answer 10

2 (k - 4) - 3 (2k - 1)

Answer 11

[AI-generated answer — Bot GPT 3.5]

To simplify the expression 2(k - 4) - 3(2k - 1), we will first distribute the coefficients.

Distributing the 2:
2(k - 4) = 2k - 2(4) = 2k - 8

Distributing the -3:
-3(2k - 1) = -3(2k) - 3(-1) = -6k + 3

Now we can rewrite the expression as:
2k - 8 - (6k - 3)

Next, we will remove the parentheses by distributing the negative sign:
2k - 8 - 6k + 3

Now we combine like terms:
(2k - 6k) + (-8 + 3) = -4k - 5

Therefore, the simplified expression is -4k - 5.
