C is true and most likely the correct answer
Answer:
31 students will be going on the trip.
Step-by-step explanation:
Create an equation.
60x+40x+30x=4030
Combine like terms.
130x=4030
Divide.
x=31
Checking solution...
60(31)+40(31)+30(31)=4030
1860+1240+930=4030
4030=4030

I’ll try, hopefully I get it right
17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
Since L1//L2 , angle 1 = angle 5
