To find this, you have to turn them into inproper fractions. You do this by doing denominator x whole number x numerator. The equation is now 14/3 x 27/4. You have to do numerator x numerator and denominator x denominator which will lead us to an answer of 378/12 or 31 6/12 or 31 1/2
Substitute the given value of three into the equation so that it becomes
M= 3.5*3+2
M= 12.5
Answer: the answer is 7/48

Answer:
Small candles cost 1 dollar, large candles cost 5 dollars.
Step-by-step explanation:
Let s represent small candles, L represent large candles.
You: 15 = 5s + 2L
Friend: 21 = 6s + 3L
Now you can solve for s and L, the cost of each candle type!
15 = 5s + 2L Multiply this equation by 3 -> 45 = 15s + 6L
21 = 6s + 3L Multiply this equation by 2 -> 42 = 12s + 6L
Now we have equal L's in both equations. Use elimination to get rid of L! Subtract the equations from each other.
45 = 15s + 6L
- 42 = 12s + 6L
------------------------
3 = 3s + 0L
Now solve for s.
3 = 3s
<u>s = 1 dollar</u>
Plug s back in to get L.
15 = 5s + 2L
15 = 5(1) + 2L
15 = 5 + 2L
10 = 2L
<u>L = 5 dollars</u>
It is closer to 1 hope i helped
