53x12=636 that is your answer that is the way to estimate it your answer is 636 that is how many students can be seated
Step-by-step explanation:
well first try by addding the numbers and then dived it by 2
Answer:
45
Step-by step
What do we already know about the equation?
We know that they EACH bought a hockey puck($17) and 2 shirts
Half of 214 is 107. So they had to have spent 107 separately
So we make the equation and let s represent shirts
2s + 17 = 107
- 17 -17
2s= 90. DIVIDE by 2
s = 45
the answer is Probably C.
P=44.6
P=a+b+√a^2+b^2=11+15+√11^2+15^2≈44.6
