PLZ HELP 5 3/5 + 3/4 + 2 1/2

8 17/20

Step-by-step explanation:

1. (make all the fraction have the same denominator)the denominator is 20...

3/5= 12/20  3/4=15/20 1/2=10/20

2. (add) 5 12/20 + 15/20 + 2 10/20 = 7 37/20

3. (there is an improper fraction) u have to subtract 37-20...37-20=17 now add 1 hole number to the faction and put 17 over the 20 like this...17/20...now ur answer will be 8 17/20

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
