Answer: x=12
Step-by-step explanation: x - 5 =12 the inverse operation of subtracting is adding so add 5 to both sides and you are left with x=7 + 5 the 5 on the left side cancels each other out so now all you do is add 5 to 7 and your left with x = 12
Answer:
b
Step-by-step explanation:
Answer:
V= 21.7
Step-by-step explanation:
180-90=90
2v+v+25=90
3v+25=90
3v=65
V=21.7
Reduce the numbers by dividing both by 2.4 to get the distance traveled per min which is 90.05 meters a min, so every min its altitude decreases by 90.05 meters

A.) 10(-4/5)^x
10(-4/5)^1 = -8
10(-4/5)^2 = 6.4
10(-4/5)^3 = -5.12
10(-4/5)^4 = 4.096
