Answer:
x=8 x=-8
Step-by-step explanation:
-3|x|=-24
Divide each side by -3
-3|x|/-3=-24/-3
|x|=8
There are 2 solutions a positive and a negative
x=8 x=-8
Answer:
80
Explanation:
Since it rises at a rate of 40 feet per minute, just multiply 40 times 6 to get 240. Then subtract 320 minus 240 to get 80
Answer:


x(0)=20,y(0)=5
Step-by-step explanation:
We are given that
Tank A contains water=80 gallons
x(0)=20,y(0)=5
Tank B contains water=30 gallons
Rate=4 gallon/min
Concentration of salt is pumped into tank=0.5 pound /gallon of water
Solution pumped from tank A to tank B at the rate=6 gallons/min
Solution pumped from tank B to tank A at the rate=2gallon/min
Solution from tank B is pumped out of the system at the rate=4 gallon/min
We have to find the DE at time t
For x
Rate in=
Rate in=
Rate out=
Rate out=3x/40[/tex]
Rate in-Rate out


For y
Rate in=
Rate in=3/40x
Rate out=
Rate out=y/5
Rate in-Rate out

Answer:
-4 *-4 *-4
= 16*-4
= ANWSER
-9*-9
=81
Step-by-step explanation:
Milo owns 27 action-adventure DVDs.
45 (total) x 0.4 (% of comedies) = 18 (# of comedy DVDs).
45 - 18 = 27 (# of action-adventure DVDs)
Or
100 (total %) - 40 (% of comedies) = 60 (% of action-adventures)
45 (total) x 0.6 (% of action-adventure DVDs) = 27 (# of action-adventure DVDs)
