Answer:

\boxed{i=\dfrac{P-2w}{2}=\dfrac{P}{2}-w}

Step-by-step explanation:

l - length

w - width

2l+2w=P\qquad\text{subtract 2w from both sides}\\\\2l-2w-2w=P-2w\\\\2l=P-2w\qquad\text{divide both sides by 2}\\\\\boxed{l=\dfrac{P-2w}{2}}\\\\or\\\\l=\dfrac{P}{2}-\dfrac{2w}{2}\\\\\boxed{l=\dfrac{P}{2}-w}

p = 2i + 2w

Subtract 2w from each side:

p-2w = 2i

Divide both sides by 2:

p-2w / 2 = i

Dmitry [639]

Step-by-step explanation:

1)X represents the time he spent in cardio.

Y represents the time he spent in weighted.

2)If you could put the options on the second one it would be better.

3)4x+y=210

3x+2y=195

y=210-4x

3x+2(210-4x)=195

3x+420-8x=195

5x=420-195

5x=225

x=45

y=30

Total time of one cardi and weighted = 75min= 5/4 h.

4)2x+4y=

90+120=210 total time of week three.
