Answer 1

what you need to tell yourself is this:

what are even integers from 8 to 16 inclusive

Answer 2

if I knew the even intergers I wouldn't be asking lol

Answer 3

well what are even integers

Answer 4

do you know what odd and even numbers are?

Answer 5

Yes

Answer 6

good. so lets list all the integers from 8 to 16

8,9,10,11,12,13,14,15,16

Answer 7

which of these numbers are even

Answer 8

8, 10, 12, 14, 16

Answer 9

hence we call this a set of even integers from 8 to 16.

Answer 10

So A is the answer?

Answer 11

yep!

Answer 12

Thanks so much! :)

Answer 13

: )

Answer 14

do you know how to Simplify [-1/4]

Answer 15

what do you mean?

Answer 16

Which value of m makes this statement true?
80 - 2m <= 8 +3m

A.4
B.7
C.12
D.15

Answer 17

just re-arrange if it were an equal sign
80 <= 8+5m
72 <=5m
so you say to yourself, what number must m be so that 5*m must be larger than 72

Answer 18

512
or
515
Both of them are larger...

Answer 19

you have options for m
A.4
B.7
C.12
D.15

Answer 20

5*4=20
5*7=35
5*12=60
5*15=75

Answer 21

so when m=15, the inequality satisfies

Answer 22

Ohhh, That's how you solve that.. Thanks dude!
