The temperature dropped 3C every hour for 5 hours right in integer that represents the change in temperature
Sindrei [870]

Answer:

-15°C.

Step-by-step explanation:

They tell us that the temperature dropped 3 ° C every hour, therefore, the temperature change every hour = -3 ° C

They also tell us the total number of hours during which the temperature was changed = 5,

We have to:

The total change in temperature = change over an hour * total number of hours:

TC = - 3rd * 5

TC = -15 °

Then we can affirm that the integer representing the temperature change is -15 ° C.

How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Median

Arrange your numbers in numerical order.

Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

0.4(12 - 3x) = 0.3(12x - 16)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute:                                4.8 - 1.2x = 3.6x - 4.8
  2. Add 1.2x on both sides:          4.8 = 4.8x - 4.8
  3. Add 4.8 on both sides:           9.6 = 4.8x
  4. Divide 4.8 on both sides:       2 = x
  5. Rewrite:                                   x = 2
