Answer:
Width is 10 Length is 20
Step-by-step explanation:
Perimeter = 60
Length = W + 10
P = 2L + 2W Write the equation for perimeter
60 = 2(W + 10) + 2W Substitute your variables
60 = 4W + 20
- 20 - 20 Subtract 20 from both sides
40 = 4W Divide both sides by 4
10 = W
Answer:
D. y=2x-2
Step-by-step explanation:
once you plot the points, you see that the y-intercept is -2 and the rise over run is 6/3. you simplify 6/3 by dividing and get 2x. So y=2x-2.
Hope this helped!

Answer:
t ≅ 5.09 min
Step-by-step explanation:
we have that if in 4000 L/sol there is 132 kg salt and the pumping speed is 12L/s, we must find how much of salt is pumping per second and then find the amount of salt remaining
12L/s*132kg salt/4000L = 0.396 Kg salt/s, this means that 0.396 kg per second comes out
, It should be found that the amount of salt must be drained so that only 11 kg of salt remain
132kg salt - 11 kg salt = 121 kg salt, so
121Kg salt*s/0.396Kg salt ≅ 305.55 s ⇒ 305.55s*min/60s ≅ 5.09 min
