10% of 140 is 14.
to solve you first must do 10/100 = 14/x
cross multiply and you get 10x = 1400
divide 1400 by 10 and you get 140
Answer:
You make a factor tree for (-)40 where the factors of -40 are -8 and +5. This becomes (x+5)(x-8) which can be multiplied to get back to the starting point.
Answer: The answer is 500,000.
Step-by-step explanation:
100% - 30% = 70%
x => 100%
350000 => 70%
x = 350000*100% / 70%
x = 500000
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
