Answer:
1200 students at the school
Step-by-step explanation:
Let x be the total number of students at the school
50% ride the bus
600 students ride the bus
x*50% = 600
Changing to decimal form
.50x = 600
Divide each side by .5
.50x/.5 = 600/.5
x =1200
1200 students at the school

Answer:
1 9/10
Step-by-step explanation:
3 1/10 = 3.10
1 1/5 = 1.2
3.1 - 1.2 = 1.9
1.9 = 1 9/10
Hope this helped!
Answer: I wouldn’t be able to make a linear system right now, but it would be better to use Hamster Fun if it were long-term, and Hamster Heaven if it were short-term.
Step-by-step explanation:
HH (Hamster Heaven) charges 20$ plus one a day, and HF (the other) charges 35 plus one a day, so if you went for 80 days for either one:
HH: 20 + (2.50 x 80) =
20+200: 220
HF: 35 + (1 x 80)= 115
If it were for only a day or two, it would be more efficient to use Hamster Heaven.
