Answer:
x = 90
Step-by-step explanation:
- x - x + x = - 70
Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions
- 40x - 4x + 9x = - 3150 , that is
- 35x = - 3150 ( divide both sides by - 35 )
x = 90
Using proportions, the approximate length of time, in years, for the watch to lose exactly 24 hours is:
(d) 240.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
24 hours have 24 x 3600 = 86400 seconds, hence the <em>rule of three</em> is given by:
One second - 1/365 year
86400 seconds - x years
Applying cross multiplication:
x = 86400/365
x = 240.
Hence option D is correct.

distributive property is when you take the number on the outside of the parenthesis and you, well, distribute it to the inside numbers.
so
35(5 + 7)
you have to do 35 * 5 and 35 * 7
its 175 and 245, and then you add those to get 420
same with 12
12 * 6 and 12 * 5
that's 72 and 60
72 - 60 = 12
you minus cause in the parenthesis it's a minus symbol in this case
please thanks if this helped or if u need more help just ask me
