Answer:
Step-by-step explanation:
did not go on the class field trip = 360 -315 = 45.
315 did
therefore
360-315=45 didnt
45/360 students didnt go on the trip
so to turn this into a percentage, just multiply this fraction by 100:
45/360*100 = 12.5%
0.09125%
Divide 73 by 800 and you will get 0.09125
-81
-6(2x² + 5x) - 9
substitute -4 for 'x'
-6[2(-4)² + 5(-4)] - 9
-6[2(16) + (-20) - 9]
-6(32 - 20) - 9
-6(12) - 9
-72 - 9 = -81
