It's 6 because you have to divide 
=
. You cross multiply then you divide by 100 then you get your answer.
Answer:
9:22
Step-by-step explanation:
9 is the boys 13 is the girls
22 is the total
-13>-5x+2>-28 subtract 2 from all expressions
-15>-5x>-30 divide each expression by -5
Be sure to reverse direction of signs when you divide/multiply by a negative value!
3<x<6
So the "graph" will be a infinitely high plane, or area, contained between the two vertical lines x=3 and x=6
X=$30
y=$60
1 hour job- 60x1=60+30=90
3 hour job-60x3=180+30=210
Assuming 0 and 100 are included in the possible choices:
There are
multiples of 7 between 0 and 100, so there is a
probability of choosing a multiple of 7.
