Answer:

$\large\boxed{5\dfrac{1}{2}}$

Step-by-step explanation:

$n-the\ number\\\\\text{the quotient of a number and two}:\ \dfrac{n}{2}\\\\\text{the quotient of a number and two, increased by 10}:\ \dfrac{n}{2}+10\\\\\text{six less than the quotient of a number and two, increased by 10}:\\\\\left(\dfrac{n}{2}+10\right)-6\\\\\text{Put n = 3 to the expression:}\\\\\left(\dfrac{3}{2}+10\right)-6=\left(1\dfrac{1}{2}+10\right)-6=11\dfrac{1}{2}-6=5\dfrac{1}{2}$

Answer:

1. 15.1%

2. 8.3%

3. 12%

4. 25%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

percent change = (21300 - 18500)/(18500) * 100%

percent change = 15.1%

A positive percent change is a percent increase.

Answer: The percent increase is 15.1%.

percent change = (new number - old number)/(old number) * 100%

percent change = (298000 - 325000)/(325000) * 100%

percent change = -8.3%

A negative percent change is a percent decrease.

Answer: The percent decrease is 8.3%.

percent change = (new number - old number)/(old number) * 100%

percent change = (110 - 125)/(125) * 100%

percent change = -12%

A negative percent change is a percent decrease.

Answer: The percent decrease is 12%.

percent change = (new number - old number)/(old number) * 100%

percent change = (1500 - 2000)/(2000) * 100%

percent change = -25%

A negative percent change is a percent decrease.

Answer: The percent decrease is 25%.

8% as a decimal???????????????????????????????

ioda

Answer: .08

Step-by-step explanation: To write 8% as a decimal, we move the decimal point 2 places to the left. Filling in the missing position with a 0, we have .08.

Notice that 8% translates to the decimal .08 not .8.

Watch out for this common mistake.

Give two examples of addition of two mixed numbers with different denominators SHOW ALL STEPS

Lady bird [3.3K]

Answer:

First Example: 3 1/2 + 4 3/4, Second Example: 6 3/8 + 7 9/15

Extra Example: 8 4/20 + 3 5/10

Step-by-step explanation:

First Example:

1/2 + 3/4

1/2 is equal to 2/4 so it is now compatible to be added to 3/4.

2/4 + 3/4

= 5/4

Now for the mixed numbers since its 3 and 4, 3 + 4 = 7.

Final answer is 7 5/4.

Second Example:

3/8 + 9/15

9/15 can be reduced to 3/5

Now the equation is 3/8 + 3/5

= 15/40 + 24/40 is an equivalent equation

15/40 + 24/40

= 39/40

Now for the mixed numbers since its 6 and 7, 6 + 7 = 13

Final answer is 13 39/40.

I am going to include one last example just in case you need one:

Third Example:

4/20 + 5/10

We can reduce these to

1/5 + 1/2

= 2/10 + 5/10 is the equivalent equation

2/10 + 5/10

= 7/10

Now for the mixed numbers since its 8 and 3, 8 + 3 = 11.

Final answer is 11 7/10.

I Hope this helps!
