(2x+5)/5 = (x-2)/3

Solve each porportion for x

Asked by Yaquelin from Houston, TX

Robert's Answer:

I'm reading your equation as ( 2x + 5 )/5 = ( x - 2 )/3.

"Cross-multiplying" refers to rewriting 'A/B = C/D' as 'AD = BC.'

Try this first.

 

Pre calculus

A factory manufactures two kinds of ice skates: racing skates and figure skates. The racing skate requires 8 work-hours in the fabrication department, whereas the figure skate requires 7 work-hours in the fabrication department. The racing skate requires 1 work-hour in the finishing department, whereas the figure skate requires 3 work-hours there. The fabricating department has available at most 208 work-hours per day, and the finishing department has no more 60 work-hours per day available. If the profit on each racing skate is $8 and the profit on each figure skate is $10, how many of each should be manufactured each day to maximize profit? (Assume that all skates made are sold.)

Robert's Answer:

Problem:  To maximize 

8R + 10F [profit]

subject to the two constraints

8R + 7F <= 208 [fab dept],

R + 3F <= 60 [fin dept].

Robert's Answer:

-9x - 13 - 9x is equivalent to -9x - 13 + (-9x).

Remember that subtracting a number is equivalent to adding its opposite. Put another way,

a - b = a + (-b).

I hope this helps, and if you need more explained, please feel free to ask. I or another tutor will be happy to assist you.

 Famous Mathematician During This Times? How Can We Learn Mathematics In Easy Way?

 

+ more- less
Asked by Jenkie from New York, NY

Robert's Answer:

Sadly, I'd say there are no famous mathematicians today, in the same sense that celebrity athletes, actors, politicians, and the like are famous.

But that doesn't stop people from going into the field and continuing the work of mathematicians past.  They just don't do it for the fame and recognition.  They do it because they are passionate about discovering truths beyond the current boundaries of our knowledge.

I wouldn't say there will never be a famous mathematician in the future, but I doubt it's likely.  The prevailing culture doesn't seem to lift academics to the heights it lifts other parts of society.

As far as the other question, about learning the easy way, I'd say think twice before wanting it to come easy.  Learning is a choice, and it's usually the correct one.  However, anyone telling you that it should be easy, is selling you a falsehood, and potentially a dangerous one at that.  I for one want doctors to have been through some tough schooling before making life altering decisions about my healthcare.

Remember that anything gained with ease, can sometimes be hard to hold onto.  Whereas knowledge gained through hard work, will often be difficult to forget.  Something to think about.

Robert's Answer:

Read the instructions for this problem carefully, and make sure you have included them in this post.

As you've written it here so far, I can't figure what the problem is asking you to do.

I certainy could guess, but that wouldn't be too instructive, and I would really like to help.
