Hello,
Let's x then number of students.
x is divisible by 12,15,18 thus by 180 (lcm)
x=180*k is a square
2²*3²*5*k= a square ==> k=5
x=180*5=900
Proof:
900/12=75
900/15=60
900/18=50
900=30²
Answer: 130 miles
Explanation: make an equation. 24 + 0.10m = 37.00. subtract 24 from both sides leaving m for miles on one side. 0.10m = 13.00. now divide both sides by 0.10 leaving m by itself and making the equation m = 130.
Answer: X = 1
Step-by-step explanation:
3 x 
+ 4 + 1 = 
+ 4
First, you would want to cancel out the equal terms, in this case its the +4's
3 x + 1 =
I would also change the into a 1
3 x 1 +1 =
Now multiply and add
3 + 1 =
4 =
divide both sides by 4
x = 1
Hopefully this helps
C=10
