Answer:
x<-8
Step-by-step explanation:
four more than twice a number = 4+2X
is less than negative twelve = <-12
4+2X<-12
(4-4)+2X< -12-4
2x<-16
X<-8
The equation which represents the change in elevation of the mountain climber as he descends the cliff is; c = -2.5s.
<h3>What is the change in elevation c of the climber in terms of seconds?</h3>
It follows from the task content that the change in elevation of the climber is to.be represented by c and since the rate of descending the cliff is given as; 2.5 ft/second.
Therefore, the required equation is; c = -2.5s.
