Answer:

3 1/10

Step-by-step explanation:

You can make 3 1/2 an improper fraction and then subtract it from 2/5

We do across so 7 x 5 is 35. 2 x 2 is 4. 2 x 5 is 10. 35 - 4 is 31. 31/10 simplified is 3 1/10.

So your answer is: 3 1/10

A.T.Q, equations will be:

x+y = 450

2x+5y= 1800

Substitute value of x from equation (1), in equation (2)

2(450-y) +5y=1800

900-2y+5y=1800

3y=900

y=300

so, your answer is 300

What is the correct equation ​
Andrej [43]

Answer: y = 0.4x

In fraction form, this is y = (2/5)x

================================================

Explanation:

For each row, divide the y over x values

  • Row One: y/x = 0.8/2 = 0.4
  • Row Two: y/x = 4/10 = 0.4
  • Row Three: y/x = 6/15 = 0.4
  • Row Four: y/x = 10/25 = 0.4

We end up with the same thing each time.

Since y/x = 0.4, this rearranges to y = 0.4x

Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4
