<h3>
Answer: B) he made his first mistake in step 5. He used the statement he was trying to prove as a reason.</h3>
The goal of the proof is to show that SP = SQ. This should be the very last line of the proof. We cannot use this as support or reasoning for other steps (because we haven't proven it to be true or not). This is known as circular reasoning. The term "equidistant" means "equally distant", so in other words, Jaime is trying to prove that S is equally distant to the points P and Q.
The cost per foot of redwood and of pine is $3.5 and $1.5 respectively.
<h3>How to solve simultaneous equation?</h3>
let
- cost of redwood = x
- cost of pine = y
50x + 70y = 280
100x + 60y = 440
Multiply (1) by 2
100x + 140y = 560
100x + 60y = 440
subtract to eliminate x
80y = 120
y = 120/80
y = $1.5
substitute y = 1.5 into (1)
50x + 70y = 280
50x + 70(1.5) = 280
50x + 105 = 280
50x = 280 - 105
50x = 175
x = 175 / 50
x = $3.5
