Answer:

Andrew has 30 goldfish and Todd has 10 goldfish

Step-by-step explanation:

Lets call A the number of goldfish Andrew has and T the number of goldfish Todd has.

Andrew has 10 more goldfish than Todd:

A = T + 10

Together they have 50 goldfish:

A + T = 50

Lets replace A = (T + 10) in the las equation:

T + 10 + T = 50

Lets solve T in this equation:

2T + 10 -10 = 50 -10

2T /2 = 40 /2

T = 20

Todd has 20 goldfish

Now lets calculate A = T + 10 = 20 + 10 = 30

Andrew has 30 goldfish

Here, we are missing the slope and the y intercept. 

Lets look for the y intercept first. 

Where does it cross the y axis?  At 3!!

3 is the y intercept. 

Now, find the slope by using the slope formula. 

m =  \frac{y2 - y1}{x2 - x1}
(0,3) and (2,1)

m = 1-3/2-0 = -2/2 = -2/2 = -1
m = -1

Okay, so we found our slope, now just write the equation. 

Answer: y = -1x + 3

How do you make 22 percent into fraction in simplest form
exis [7]

22% in fraction form is 22/100 or 0.22, but it isn't the simplest form.

To put 22/100 into a simplest form, you must divide the numerator <em>and </em>the denominator by a common multiple.

22/100 or 0.22 is divisible by 2. Therefore, you can divide 22/100 by 2.

Equation:

22/100 divided by 2/2 =  11/50

Hence your answer, 11/50

Hope this helps!
