Answer:
16 because 3×4 =12 and 16-12 is 4 so 4×3
Answer:
k=16
Step-by-step explanation:
3(k − 12) = 12
distribute the left side
3k-38=12
add 38 to both sides
3k=48
divide by 3 on both sides to k by itself
k=16
After a power failure, the temperature in a freezer Increased at an average rate of 3.5 °F per hour. The total Increase was 24.5 °F. Enter and solve an equation to find the number of hours until the power was restored. Let x represent the number of hours it takes for the temperature to increase to 24.5 °F.

<Please fill in the blanks I will give you brainliest if you answer correctly>
Answer:
3.5x=24.5
3.5x7=24.5
X=7
Step-by-step explanation:
3.5 times what equals 24.5
3.5x1=3.5
3.5x2=7
3.5x3=10.5
Keep doing this and increase the number you are multiplying 3.5 by until your answer is 24.5.

A paper cup is dropped and its landing position is recorded. The cup can land on the side, on the open end, or on the closed end. The results of 20 trials are shown in the table below:
A chart shows tally marks. Main title for the chart is Paper Cup Experiment. The title for the second column is Number of times occurred. The tally mark corresponding to open shows a set of 4 vertical lines cut by a slanting line. The tally mark corresponding to closed shows a set of 4 vertical lines cut by a slanting line and a set of 3 vertical lines. The tally mark corresponding to side shows a set of 4 vertical lines cut by a slanting line and a set of 2 vertical lines.
Based on the table, which of the following best compares the experimental probability of the cup landing on its open end with the experimental probability of the cup landing on its closed end? (1 point)
The probabilities are equal.
The probability of landing on the open end is greater.
The probability of landing on the closed end is greater.
No conclusion can be made.

The approximate number of pink chips is 40. Here's why: what you need to do is set up the problem as shown below. 12 goes above 30 because you have to know what the total number of chips chosen is in order to relate it to 100 chips. From there, all you have to do is cross-multiply and divide (or my middle school teacher used to call it fish.... I'll explain why). First you are going to draw a line from the 100 to the 12 and multiply them. then you are going to curve the line that you will draw from the 12 to the 30 and divide the product of 12 and 100 by 30. Then you will draw a line from the 30 to the X meaning that the quotient that you find from the product of 120 and 100 divided by 30 equals X. Hope that helps.

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices
Rosemary needs to maintain 126 mph.
Rosemary needs to maintain 65 mph.
Rosemary needs to maintain 56 mph.
Answer:
56 mph
Step-by-step explanation:
Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84
Answer:
56
Step-by-step explanation:
84 / 1.5 = 56
