Answer:
The equation to solve the problem is
306 = 249 + x
x = 306 - 249
Hence:
57 students went outside
Step-by-step explanation:
Let the number of students outside be represented by x
Hence:
Number of students in the cafeteria = Number of students inside - Number of students who went outside
We are told:
There were 306 students in the cafeteria. After some went outside, there were 249 students left in the cafeteria.
The equation to solve the problem is given as:
306 = 249 + x
x = 306 - 249
Hence:
x = 57
57 students went outside
(x + x - 14) + 7 = 85
2x - 7 = 85
2x = 92
x = 46
One number is 46, and the other is 32.
Answer: Option C 31.68 km/h
Solution:
Speed=s=8.8 m/s
s=? kilometers per hour=? km/h
s=(8.8 m/ 1 s)*(1 km / 1,000 m)*(3,600 s / 1 h)
s=(8.8*1*3,600)/(1*1,000*1) km/h
s= 31,680/1,000 km/h
s=31.68 km/h
