3.75
Answer:
x=(-9±√51)/3
Step-by-step explanation:
3x(x + 6) = -10
3x²+18x=-10
3x²+18x+10=0
solve using uadratic formula a=3,b=18 anc c=10
x= (−b±√b^2−4ac)/2a
x=[-18±√18²-4(3)(10)]/2(3)
x=(-18±√18²-120)/6
x=(-9±√51)/3
Answer:
125 students ride their bike to school
Step-by-step explanation:
We can set a proportion.
5 / 32 = x / 800
where x is the number of students out of 100 who ride their bikes.
Cross multiply.
32x = 4000
Divide both sides of the equation by 32.
x = 125
125 students out of 800 students ride their bikes to school.
