How do i solve this?
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Let the part of it that's being invested at a rate of 5% per annum be x. Let he other part that's being invested at 7.2% "5000x".
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
can it not also be y ?
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Why would you want two variables when you can solve it using one? Do you want to make your life harder?
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
Its because i am learning graphing at the moment so i thought there would be y in there

Does the question have the word sketch/draw or graphically in it?
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Then what kind of reason was that?... Now let's continue on with the question rather than giving random excuses as to what you're learning.

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Write 5% as a decimal.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Also write 7.2% as a decimal.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Sorry I meant fraction. My apologies.

50/1000 75/1000

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Make it into the simplest form please. If you don't know how to simplify fractions into its simplest form, then I suggest you use your calculator.

waheguru Group TitleBest ResponseYou've already chosen the best response.0
1/20 and 3/40
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
The question says 7.2%....not 7.5%....
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
You only got one correct. Please rewrite 7.2% as a fraction again please.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Yep you're correct.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Sorry about that, my comp lagged out.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Okay now. Do you agree that (x times 5%)+[(5000x) times 7.2%)]=349?
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Okay, now change the 5% and 7.2% into the fractions you wrote previously and show me your equation.
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
1/20 x + 9/25 (5000x) = 349
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Yep great! Excellent.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Now. You just figured the equation that would lead you to finding x. \[\frac{ x }{ 20 }+\frac{ 9(5000x) }{ 125 }=349\]
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
oh... yea
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
I'm just letting you go for just writing 25 but I will let you go this time due to the probability of that being a typo.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Okay, so when you get rid of the fractions by multiplying both sides with the Lowest common multiple, tell me what you get.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Multiply by 500 to both sides.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Tell me what you get. Afterwards, you would have to expand/distribute the brackets/paranthesis.
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
Ill do that, but just for knowledge this can also be answered by using the decimals (0.05 and 0.075) right
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
i ment 0.072
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Yea of course.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
I just reckon fractions are clearer and you would understand a bit better.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
So what did you get?
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
I find fractions a bit difficult so i did decimals, 0.05x + 0.072(5000x) = 349
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
0.05x + 3600.072x = 349
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Okay...Well then expand/distribute the brackets/paranthesis...
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
and 0.05x  0.072 = 11
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Where's the x gone mate?
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
sry (you are am amazing teacher you can catch the slighest mistakes =) 0.05x  0.072x = 11
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Okay collect likes terms. That means group the x's together.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
like terms*
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
0.022x = 11
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
x= 11/0.022
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Yep and then what do you get for the other one.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
There's two parts.
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
That's the first part where it was invested at a rate of 5% p.a
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
So what about the part where it was invested at a rate of 7.2%?
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
4500 the rest of the money
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Correct. Awesome.
 one year ago

waheguru Group TitleBest ResponseYou've already chosen the best response.0
wow, you are just an amazing teacher. thank you soo much
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
I will show what I did using fractions. This just give you a look at a different perspective in solving these. \[25x+36(5000x)=174500\] \[25x+18000036x=174500\] \[11x=180000174500\] \[11x=5500\] \[x=500\]

Azteck Group TitleBest ResponseYou've already chosen the best response.1
And no worries. Good work.

Mr, Aztech are you usually available at this time so I can ask you for help
 one year ago

Azteck Group TitleBest ResponseYou've already chosen the best response.1
Not all the time. I'm also busy with my own work. So some days I will be off doing my work and other days I will be resting and so on. This is only just a bit of fun to help others with their homework.
