Answer:
1:6 One hour of work is worth $6
Step-by-step explanation:
$18/3= $6
notice that the denominator can be factored into (x-3)(x+3).
Now you can cross out (x - 3) from the numerator and denomiantor resulting in a simplified fraction of 
Plug the limit value (which is 3) into the simplified fraction.
Answer: 
Answer:
7 teachers
Step-by-step explanation:
you decide 100 by 15 which equals 6.7 since you can't have half a teacher you round it to 7 teachers.
A line perpendicular to another will have the opposite sign and be flipped
ex: slope is 4/5 the other lines slope will be -5/4
(-2,-1) (2,-3)
slope formula
y2-y1/x2-x1
-3-(-1)
____
2-(-2)
-3+1
___
2+2
-2
___
0
the slope of the perpendicular line is 0/-2 which is just 0
Answer:
x=5
Step-by-step explanation:
The angles of a trangle have to add up to 180 degrees. With that information, we can create an equation:
27+98+(10x+5)=180
125+10x+5=180
130+10x=180
-130 -130
______________
10x=50
/10 /10
x=5
