She needs to do 9 more problems to complete her homework.

Step-by-step explanation:

Equation: 28-19

Solve: 28-19=9

#2 - 28-19 (equation), 19+9 = 28 (check), and solve : 28-19 = 9

#3 - (3)³*1/3+6

#4 - C) y * 55 + 5

Step-by-step explanation:

#2 Explanation

Since Kailey starts off with 28 math problems, and has already done 19. We need to know ONLY the remainder/ how much she still needs to do.

To do that, we must subtract 28 by 19.

28-19 = 9.

#3 Explanation

If the teacher hasn't taught you PEMDAS or Please Excuse My Dear Aunt Sally, I give you permission to yell at her.

Do Percentages first, if none, then Exponents second, if none, then Multiply third, Division 4th, Addition 5th, and then Subtraction last.

The order should be like this:

(3)³*1/3+6

#4 Explanation

y * 60 is equivalent (equal to) to y = 55 + 5

55 + 5 = 60 right?

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
