Jay volunteers at a food bank he volunteered 2 5/6 hours on Saturday 2 1/3 hours on Wednesday how many hours did he volunteered in all

5 1/6 hours

Step-by-step explanation:

Add the hours he volunteers

2 5/6 + 2 1/3

Get a common denominator of 6

2 5/6 + 2 1/3*2/2

2 5/6 + 2 2/6

4 7/6

This is an improper fraction

4 6/6 + 1/6

5 1/6

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
