Multiplication is helps to add a number multiple times. The meaning of 6 x 5 is 6 + 6 + 6 + 6 + 6.
<h3>What is multiplication?</h3>
Multiplication tells us the number of times a number is been added to itself. For example, 3 x 2 = 3 + 3 = 2 + 2 + 2
Given to us
5 x 6
As we have already discussed that multiplication is the number of times a number is been added to itself. therefore,
5 x 6 = 5 + 5 + 5 + 5 + 5 + 5 = 6 + 6 + 6 + 6 + 6
Hence, the meaning of 6 x 5 is 6 + 6 + 6 + 6 + 6.

So 2x+12=5x-9
you want all of the unknowns on one side and all of the known values on the other or
subtract 2x from both sides
12=3x-9
add 9 to both sides
21=3x
divide both sides by 3
7=x
Answer:
99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 18 minutes
Standard Deviation, σ = 4 minutes
We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.
Empirical Formula:
- Almost all the data lies within three standard deviation from the mean for a normally distributed data.
- About 68% of data lies within one standard deviation from the mean.
- About 95% of data lies within two standard deviations of the mean.
- About 99.7% of data lies within three standard deviation of the mean.
Thus, 99.7% of the customers have to wait:
Thus, 99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
The information shown here only shows a principal sum, a rate of interest and a period or time. There is no question as to what is needed. But suppose the need is for simple interest, then we calculate using the given information and the formula:
I = PRT
where I is simple interest, P is the principal, R is the rate per year, and T is time
P = 290, T is 6 months which is 0.5 years, R = 12.5 % which is written as 0.125 in decimal fraction.
I = 290 × 0.125 x 0.5 → I = 18.125
Therefore after 6 months , the interest earned will be 18. 125 dollars
