Well the answer is 43.86, but if it is asking for an estimate you’d prolly round to either 40 or 45. hope this helps
Answer: Aquaman swims at the rate of 140.47m/min
The rate of water drain is 73.81m/min
Step-by-step explanation: Let A be the rate at which Aquaman swims.
Let W be the rate at which the water drains
3(A - W)= 200 ......equation (1)
0.7(A +W)=150 ..... equation (2)
3A -3W = 200 .....equation 3
0.7A + 0.7W = 150 ..eq4
Multiply eq 3 by 7 and eq 4 by -30
21A - 21W = 1400
-21A + 21W = -4500
Subtracting both equation from each other, you get
-42W = -3100
W = 3100/42
W = 73.81m/min
Put 73.81 for W in equation 1
3A - 3(73.81) = 200
3A - 221.43 = 200
A =421.43/3
A= 140.47m/min
Answer:
3 people
Step-by-step explanation:
Reading a stem & leaf plot can be hard!
Remember in the middle or whichever side is single digits divided by the line is your tens place values.
The 2 has two values on the other side, giving us 23 & 29 laps.
The 1 has one value on the other side, giving us 11 laps.
The 0 has no other value, so there is no data for that row.
There were 3 data points below 30, & these were 11, 23, & 29.
Hope this helped. :)

Step-by-step explanation:
(g-f)(x)=g(x)-f(x)
=6x-(4-X(2))
=x(2)+6x-4
to evaluate (g-f) (#) substitute x=3 into (g-f)(x)
(g-f)=(9)+(6 x 3) -4=23
