Answer:
-8 1/2 ft / min
Step-by-step explanation:
X = second diver rate
1 1/2 X = -12 3/4
3/2 X = - 51/4
X = - 51/4 * 2/3 = - 102/12 = -8 1/2 ft / min
First you figure out what -15 divided by 3 is
-15/3= -5
Then subtract 1 to get it off the other side, whatever you do to one side you have to do to another
-5-1=x-1
The solve
-6=x
The answer is
X=-6
Ok first one when you are dealing with two step equations you need to cancel out the -6 so add 6 to both side so now you have 28 and divide that by 4 because you need to cancel out the 4
4x-6=22
+6=+6
4x=28
4x/4=28/4
X=7
