To add 9(k + 1/3) + 10(1/2k - 1), we can use the distributive property to simplify.

First, we distribute 9 to both terms inside the first parentheses: 9k + 9/3

Next, we distribute 10 to both terms inside the second parentheses: 10/2k - 10

Simplifying the fractions, 9/3 = 3 and 10/2 = 5.

Now we can combine like terms: 9k + 3 + 5k - 10

Combining like terms, we get: 14k - 7

Therefore, the simplified expression is 14k - 7.

The correct answer is C. 14k - 7.

To find the missing values, let's analyze the ratios in the table.

The first ratio can be found by dividing each y-value by the corresponding x-value: 48/8 = 6 and 60/10 = 6. So, we can conclude that the ratio is 6.

The second ratio can be found by dividing each y-value by the corresponding x-value: 72/x = 6. To find the value of x, we can divide 72 by 6: x = 72/6 = 12.

The last ratio can be found by dividing each y-value by the corresponding x-value: 84/x = 6. To find the value of x, we can divide 84 by 6: x = 84/6 = 14.

Therefore, the missing values are x = 12 and y = 14.

The correct answer is 12; 14.

To compare the ratios 3:5 and 2:3, we need to consider equivalent ratios.

By looking at the first table:

For the 3:5 ratio, we can see that every 3 corresponds to 5.
For the 2:3 ratio, we can see that every 2 corresponds to 3.

If we multiply the 2:3 ratio by 2, we get 4:6.

Now we can compare the ratios:

3:5 is not equal to 4:6 because 3 does not equal 4 and 5 does not equal 6.

Since we do not have any other equivalent ratios to compare, we cannot determine which ratio is greater or lesser.

Therefore, the correct response is: More rows need to be added to the tables to be able to compare the ratios.

To determine which type of cracker has less fat per cracker, we need to compare the ratios of grams of fat to the number of crackers for each type of cracker.

For Cracker A, the ratio of grams of fat to the number of crackers is:

8/10 = 0.8 grams of fat per cracker
16/20 = 0.8 grams of fat per cracker
24/30 = 0.8 grams of fat per cracker
32/40 = 0.8 grams of fat per cracker
40/50 = 0.8 grams of fat per cracker
48/60 = 0.8 grams of fat per cracker

For Cracker B, the ratio of grams of fat to the number of crackers is:

6/12 = 0.5 grams of fat per cracker
12/24 = 0.5 grams of fat per cracker
18/36 = 0.5 grams of fat per cracker
24/48 = 0.5 grams of fat per cracker
30/60 = 0.5 grams of fat per cracker
36/72 = 0.5 grams of fat per cracker

From the ratios, we can see that the amount of fat per cracker is consistently lower for Cracker B. Therefore, Cracker B has less fat per cracker compared to Cracker A.

The correct answer is: Cracker B.

To compare the ratios 2:5 and 3:4, we need to find a table that contains equivalent ratios for both ratios.

Let's analyze the options:

Option 1:
2:5 is present, but 3:4 is not.

Option 2:
2:5 and 3:4 are both present.

Option 3:
3:4 is present, but 2:5 is not.

Option 4:
2:5 is present, but 3:4 is not.

Therefore, the correct option is option 2:

2 5
4 10
6 15
8 20
10 25
3 4
6 8
9 12
12 16
15 20

Option 2 provides an equivalent ratio for 2:5 (4:10), as well as an equivalent ratio for 3:4 (6:8). Therefore, this table can be used to compare the ratios 2:5 and 3:4.

The correct answer is option 2.

To compare the ratios 7:4 and 12:5, we need to find equivalent ratios in the tables provided.

From the given table, we see that the first ratio, 7:4, is already provided.

To find the equivalent ratio for 12:5, we can divide 12 by 6 to get 2, and then multiply 2 by 5 to get 10. So, the equivalent ratio is 12:5 = 24:10.

Now, to fill in the missing values A and B:

Looking at the second column, we see that 24 corresponds to 10. Since 12 corresponds to A, we can set up a proportion:

12/24 = A/10

Multiplying both sides by 24, we get:

A = 12 * 10/24 = 120/24 = 5

Hence, A = 5.

Now, looking at the first column, we see that 7 corresponds to 4. So, since 5 corresponds to A, we can set up another proportion:

5/7 = B/4

Multiplying both sides by 7, we get:

B = 5 * 4/7 = 20/7

Thus, B = 20/7.

Therefore, the missing values are A = 5 and B = 20/7.

The correct answer is: A = 5 and B = 20/7.

To compare the ratios 16:18 and 5:6, we can analyze the given tables.

For the first ratio, 16:18, we can see that the second number is 2 greater than the first number.

For the second ratio, 5:6, we can see that the second number is 1 greater than the first number.

Since the second number in the first ratio (18) is greater than the second number in the second ratio (6), we can conclude that the ratio 16:18 is greater than the ratio 5:6.

Therefore, the correct answer is: 16:18 is greater.

To find the percentage of sugar in the batch of cookies, we need to divide the number of cups of sugar by the total number of cups of ingredients, and then multiply by 100.

In this case, there are 2 cups of sugar out of 8 cups of ingredients.

Calculating the percentage:

(2/8) * 100 = 0.25 * 100 = 25
