Solve the problem below by finding a common denominator.
5/6-2/5

Answers

Answer:

I know how to this in one of two ways and I'm not sure if they're correct but anything to help.

5/6-2/5 would get you 1/3 because if you cross multiply and cross out factors that can go into each you cant pretty much get that answer. ( i think)

or

the common denominator would be 30 multiply 5 by 5 and 2 by 6. 25-12 is 13. How I was taught was find a number that both denominators can go into then multiply by that number. So 6*5= 30 so you would multiply 5 by 5 to get 25.

Hope I explained this well, I don't really think so.

In 1998, Journeys sold 15 million pairs of Vans across the
U.S. In 2008, Journeys sold 45 million pairs of Vans. What
was the average rate of change in shoe sales for the store?

Answers

Answer:

3 million/year

Step-by-step explanation:

Average rate of change is the slope in same interval:

(45 million - 15 million)/(2008 - 1998) years=30 million / 10 years =3 million/year
Given:

In 1998, Journeys sold 15 million pairs of Vans.

In 2008, Journeys sold 45 million pairs of Vans.

To Find:

The average rate of change in show sales for the store.

Formula:

Final year : 2008

Initial year : 1998

Final sale : 45 million

Initial sale : 15 million

Average sales = Final sale - Initial sale / Final year - Initial year

Explanation:

Average sales = 45 million - 15 million / 2008 - 1998

Average sales = 30 million / 10 years

Average sales = 3 million / 1 year

Answer:

The average rate of change in show sales for the store is 3 million per year.

Answers

Answer: 17

Step-by-step explanation:

Each side has one line on it indicating each side is equal therefore 5y-3= 4y+1. Once you put them equal to each other you solve for y. You start by isolating the variable by inverse operations so you add 3 to both sides which leaves 5y=4y+4 and then you subtract 4y from both sides leaving y=4. Now that you found the value of y you input that value into one of the expression for one of the sides and solve. 5(4)-3= 17

The dew point in degrees Fahrenheit can be calculated with the formula DP = T (100 - RH), where DP is
the dew point, T is the dry-bulb temperature, and RH is the relative humidity. Which of these is the equation
solved for RH?
RH = 100 -
(T-DP)
RH = 100 – 2 (DP-1)
RH = 100 – (DP-1)
RH = 100 – 25 (T-DP)

Answers

Answer:

B

Step-by-step explanation:

I took that same test and i didthe practice test. Believe me.

The equation that can be used to solve for RH is 25/9(DP-T) - 100

Given the formula for the dew point in degrees, Fahrenheit expressed as

DP = T - 9/25(100 - RH)

To solve for the value of RH, we will make RH the subject of the formula;

DP = T - 9/25(100 - RH)

Subtract T from both sides:

DP - T =  9/25(100 - RH)

Multiply both sides by 25

25(DP - T) = 9(100 - RH)

25(DP - T) = 900 - 9RH

25(DP - T) - 900 = 9RH

RH = 25/9(DP-T) - 100

Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100
