54% of what is 216...
0.54x = 216
x = 216 / 0.54
x = 400....so there were a total of 400 people surveyed
1. Nakagawa siya ng 84 na cookies.
2. Inilagay niya ang mga cookies sa 7 na kahon.
3. 84 ÷ 7 = 12
4. 12 x 7 = 84
5. Ang bawat lalagyan ay may 12 na cookies sa loob nito.
Answer:
y = 1/2x -5 slope intercept form
y-1 = 1/2(x-12) point slope form
Step-by-step explanation:
We can find the slope of this line by using
m = (y2-y1/(x2-x1)
= (1--7)/ (12 --4)
= (1+7)/(12+4)
= 8/16
= 1/2
We know the slope and a point, so we can use point slope form
y-y1 = m(x-x1)
y-1 = 1/2(x-12)
y-1 = 1/2 x -6
Add 1 to each side
y-1+1 = 1/2x -6+1
y = 1/2x -5
This is in slope intercept form

Answer:
children attended= 114
adults attended= 57
students attended= 82
Step-by-step explanation:
children attended= c
adults attended= a
students attended= s
c+s+a = 253
5c + 7s + 12a = 1828
c=2a
2a + s + a =253
5*2a + 7s + 12a = 1828
3a + s = 253
22a + 7s = 1828
s = 253 - 3a
22a + 7(253 - 3a) = 1828
22a - 21a + 7*253 = 1828
a = 1828 - 7*253
a = 57
s = 253 - 3a = 253 - 3*57 = 82
s = 82
c=2a=2*57= 114
c=114
