Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
Answer:
20 trains
Step-by-step explanation:
180/9 = 20
The slope of the given line is -6, so your perpendicular line will have slope 1/6. The point-slope form of the equation of a line can be used.
.. y = (1/6)(x -12) -3
This can be simplified to
.. y = (1/6)x -5
<h2><em>750 gallons of water flows through the pipe in = 50 seconds.
</em></h2><h2><em>350 gallons of water will flow in =50/750 x 330= = </em><u><em>22 seconds.</em></u></h2>
Multiply x/3 by 5
and 2y/5 by 3
to give common denominator of 15
5x/15 + 6y/15
= (5x + 6y) /15
i hope this is what you need
5x + 6y
______
15
