5.a) Steve - 60=5×12
 = <u>5×3×2×2</u>
5.b) Ian - 60=6×10
 = <u>3×2×5×2.</u>
<u>Discussion</u> - The prime factors reduce to the same numbers in both Steve's and Ian's case.
5.c) Case 1 of 48 = 6×8
 = <u>3×2×2×2×2.</u>
 Case 2 of 48 = 12×4
 = <u>2×2×3×2×2.</u>

Answer:
B. 126 degrees
Step-by-step explanation:
lets say the angle is x
the equation we have here is the 8th graders divided by the total number of students is equal to x divided by 360 degrees since a circle has a 360 degree angle. 
The equation is:
350/1000=x/360
in number form.
350/1000= 0.35 = 35%
so now we know x/360=35%
126/360=35%
so the answer would be 126 degrees.

Answer: 
X <= 4
Step-by-step explanation:
-3x - 24<= -36
Make -3x the subject, by carrying -24 to the other side 
Note: Moving -24 to the other side changes to + 24
-3x <= -36 + 24
-3x <= - 12
Minus cancels minus
3x <= 12
Divide both sides by 3,to get the value of x 
3x/3 <= 12/3
x <= 12/3
x <= 4
Therefore, x equals to 4
