Answer 1
Answer:

Answer:

7 years

Step-by-step explanation:

Given: A chess club has 500 members but is losing 30 members each year. A computer club has 150 members and is gaining 20 members per year

To Find:  Write and solve an equation to find the number of years it will take for the two clubs to have the same number of members

Solution:

Total members in chess club= 500

chess club loosing members each year = 30

Number of members in chess club in year \text{x}

                                                                500-30\text{x}

Total members in Computer club= 150

chess club gaining members each year = 20

Number of members in chess club in year \text{x}

                                                                150+20\text{x}

Now,

When chess club and computer club have equal number of members

                     500-30\text{x}= 150+20\text{x}

                     500-150=30\text{x}+20\text{x}

                     350=50\text{x}

                     \text{x}=7

So,

It will take 7 years for two clubs to have the same number of members.

Answer 2
Answer: Well for this a t-chart type of graph would help but here's how you can do it:

key: ChC = chess club
       CmC = computer club

ChC = 500 members        ChC = losing 30/yr
CmC = 150 members        CmC = gaining 20/yr

year 1 :     ChC     CmC
members: 470   /   170

or.... you can scrap that, here's the simpler version : 
500 - 30x = 150 +20x

solution: x = 7

Hope this helps!

1/3

Answers

1 whole and 1/4 substracted to 1/3 can be written as:

1 1/4 - 1/3 =
= 5/4 - 1/3

We have to find a common denominator which is 12:

5/4 = 15/12
1/3 = 4/12

So now we just substract numerators:

15/12 - 4/12 = 11/12

These numbers simplified is 3/5
To find an equivalent fraction to 3/5 we can multiply the numerator and the denominator by any same number. lets do it with 2:-

(3)/(5)


(3*3)/(5*3)= (9)/(15)

So, a fraction equilateral tt 3/5 is 9/15.
