Considering the perimeter of the triangle, it is found that the lengths of the sides are given by:

19 feet, 22 feet, 35 feet.

<h3>What is the perimeter of a triangle?</h3>

The perimeter of a triangle is given by the sum of the lengths of it's sides.

For this problem, we consider the sides as:

x, y and z.

The perimeter is of 76 feet, hence:

x + y + z = 76.

The second side of a triangular deck is 3 feet longer than the shortest side, hence:

y = x + 3.

A third side that is 3 feet shorter than twice the length of the shortest side.

z = 2x - 3.

Applying everything at the perimeter equation, we have that:

x + y + z = 76.

x + x + 3 + 2x - 3 = 76.

4x = 76.

x = 76/4

x = 19.

Then the other variables are:

  • y = x + 3 = 22.
  • z = 2x - 3 = 2(19) - 3 = 35.

The lengths are:

19 feet, 22 feet, 35 feet.

John is trying to drain a swimming pool. He has two pumps, but he can only use one at a time. He knows that the time a pump take
xeze [42]
What do you mean this sentence?
the time a pump takes to drain the pool varies inversely with the power in watts of the pump,
The meaning would be : if we have a power in watts greater the time to drag the pool will be less because the relation between power and time is inverse.  

40 watts--------------5 hours) 
100 watts------------  x

because the relation between power and time is inverse, we multiply directly.
40 watts(5 hours)=100 watts x
x=(200 watts hours) / 100 watts=2 hours.

Answer: the time would be 2 hours.   (the new pump is faster)

4x+3y=20<br> 2x+y=7<br> How do I solve this? I forgot how to do it :/ also no answer choice
Crank

So for this, I will be using the substitution method. Firstly, subtract both sides in the second equation by 2x: 4x+3y=20\\ y=7-2x

Next, substitute y in the first equation with 7-2x, then solve for x from there:

4x+3(7-2x)=20\\ 4x+21-6x=20\\ -2x+21=20\\ -2x=-1\\ x=\frac{1}{2}

Now that we got x, substitute it into either equation to solve for y:

4*\frac{1}{2}+3y=20\\ 2+3y=20\\ 3y=18\\ y=6\\ \\ 2*\frac{1}{2}+y=7\\ 1+y=7\\ y=6

In short, x = 1/2 and y = 6.
