d=sqrt ((x2-x1)^2+(y2-y1)^2 )

Find length of AB

d=sqrt((2-(-4))^2+(0-5)^2)

d=sqrt(6^2+(-5)^2)

d=sqrt(36+25)

d=sqrt(61)

d= around 7.8

Find length of BC

d=sqrt((4-(-4))^2+(10-5)^2)

d=sqrt(8^2+5^2)

d=sqrt(64+25)

d=sqrt(89)

d= around 9.4

Find length CD

d=sqrt((8-4)^2+(7-10)^2)

d=sqrt(4^2+(-3)^2)

d=sqrt(16+9)

d=sqrt(25)

d=5

Find length DE

d=sqrt((4-8)^2+(5-7)^2)

d=sqrt((-4)^2+(-2)^2)

d=sqrt(16+4)

d=sqrt(20)

d= around 4.5

Find length EA

d=sqrt ((4-2)^2+(5-0)^2 )

d=sqrt(2^2+5^2)

d=sqrt(4+25)

d=sqrt(29)

d= around 5.4

<h2>Answer: x=-2(-y+4)</h2>

Step-by-step explanation:

-2x+4y=16

Subtract 4y from both sides

-2x+4y-4y=16-4y

Simplify

-2x=16-4y

Divide both sides by -2

-2x/-2=16/-2- 4y/-2

A teacher has 396 pieces of candy. If there are 44 students, 6 of whom are boys, if divided evenly, how many pieces of candy wil

KATRIN_1 [288]

Answer:

9 pieces of candy.

Step-by-step explanation:

The information about how many boys there are is irrelevant, so we can just ignore that.

The important information is that the teacher has 396 pieces of candy and that it is split between 44 students equally.

So, to solve, we just do 396 / 44 = 9.

Therefore, each student will get 9 pieces of candy.
