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

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).
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).
4 (g - 2) + (g + 2)
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.
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.
(h + k) - (2k - h)
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.
(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.
(p - 3) - (2.4 + 2p)
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.
(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.
2 (k - 4) - 3 (2k - 1)
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.
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.
Thank you so much bot!
