Step-by-step explanation:
24% = 156
1% = 24%/24 = 156/24 = 6.5
100% = 1%×100 = 6.5×100 = 650
so, 650 students were surveyed.
5.308 would be the correct answer
Answer:
Step-by-step explanation:
Given that:
x + 4y = 30
x - 2y = 0
Subtracting both equations:
6y = 30
y = 30/6
y = 5
Putting in above equation
x + 4(5) = 30
x + 20 = 30
x = 10
