Answer:

n = 5.4

Step-by-step explanation:

Equation: 4n = 21.6

To solve this equation for n, divide both sides by 4 to get n by itself.

Step 1: Divide both sides by 4

4 * n / 4 = 21.6 / 4

n = 5.4

Answer: n = 5.4

What is the average of the following numbers: 18, 64, 23, 78, 82, 91

Katen [24]

To Find The Answer, We Need To Add All Of Them Together, Then Divide By the Number Of Values. So:
64+23+78+82+91
-----------------------
5

64+23+78+82+91 = 338.

338
-----
5

338/5 = 67.6

So, The Average Is 67.6

At the beginning of the week, a puppy weighed 5/14 pounds. During the week, the puppy gains 8 ounces.

Mekhanik [1.2K]

Answer:

51/12

as a mixed number

4 1/4

Step-by-step explanation:

first you add 8 to 4 which is 12

so the improper fraction would be 51/12

how to turn it in to a mixed number in simplest form

step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 51 by 12 and keep only what is to the left of the decimal point:

51 / 12 = 4.2500 = 4

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

51 - (12 x 4) = 3

Step 3 - Put Together

Keep the original denominator and use the answers from Step 1 and Step 2 to get this:

Step 4 - Minimize

Minimize the fraction part from Step 3 by dividing the numerator and denominator by 3, which is the greatest common factor, to get the final answer. 51/12 as a Mixed Number is:

The graph below shows the annual cost (green) and sales (red) of a company. What is the break-even point?

s344n2d4d5 [400]

The break-even point for the graph is at 11 units.

Step-by-step explanation:

Break-even point refers to the point on the graph where either of the parameters of the graph intercepts each other. The corresponding location of the position where the intersection occurs gives the break-even point.

In the graph annual cost is plotted in green on the Y axis, while the sales are plotted on x-axis in red.

When we observe the graph carefully, we find that two-line intercepts. When the point at which interception occurs is extended on the x-axis, the point is 11 units, which gives us the break-even units.

Hence the point is 11 units.
