18. The answer is 18 because the wire is 15ft and the pole is 3ft taller than the wire
Answer:
18.3
Step-by-step explanation:
:]
3v - 9 = 7 + 2v - v I'm assuming this is the equation. If not leave a note. Combine vs.
3v - 9 = 7+v Add 9 to both sides.
3v = 7 + 9 + v
3v = 16 + v Subtract v from both sides.
3v - v = 16
2v = 16 Divide by 2
v = 16/2
v = 8
You would set up a proportion for people that choose beach/ total
So (14+17+19)/(50+50+50) which simplifies to 50/150 or 1/3
From here we can set 1/3 = x/1200 and solve for x
To do this we would multiply each side by 1200 to isolate x
(1/3)×1200= 400
So x=400
Therefore, 400 people can be expected to pick the beach
The first step to solve this problem is to compute for the
total money of Veronica. You can do this by:
$35 (given to bill) / 20% (percentage of her money given to
Bill) = $175
Since you already know the total money of Veronica, you can
now compute how much she spent to buy books which are 50% of her remaining
money after giving Bill $35.
($175 - $35) x 50% = $70
Therefore, she spent $70 for her books.
$175 – $35 – $70 = $70
Therefore, she has $70 left.
