The school carnival is divided into sections. The dunk tanks are in 1/10 of the carnival. Games are in 4/10 of the carnival. Student exhibits are in 5/10 of the carnival.
PART A
what fraction of the carnival is dunk tanks and games?

the fraction of the carnival with dunk tanks and game is__

PART B
how much greater is the part of the carnival with student exhibits that the one with games? explain how you could use a model to find the answer

PART A: 5/10

PART B: 1/10 greater

Step-by-step explanation:

PART A:

To find the fraction, you add the dunk tanks and games together. This is because you want to know what fraction of them combined, so it is 1/10 + 4/10, the given fractions of the games. Because these already share a common denominator, you would add the numerators, but the denominators stay the same, meaning the answer is 5/10.

PART B:

You know that the games make up 4/10 of the carnival, and student exhibits 5/10 of the carnival. Because they have the same denominator, you can subtract the fractions. You want to know the difference, so you do 5/10 - 4/10. This gives you the answer of 1/10. You could use a model to find the answer by making a bar graph. You can compare the bars of the sections you are looking at, and you can see the difference.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
