4/5x + 4/3 = 2x....there are 2 ways to do this...one with fractions, one without.
with :
4/5x + 4/3 = 2x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
4/3 * 5/6 = x
20/18 = x
10/9 = x
without :
4/5x + 4/3 = 2x....multiply by common denominator of 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x
20% of 36.69 is 7.338
36.69 + 7.338 = 44.02800 divided by 4 = $11.007 (rounded)
Each friend paid $11.01
You can use scale to solve. 5185/8.5=610
4845/610= about 8 hours.
M=6/5 and n = sqrt(2), is rational (but not an integer) and n is irrational.
The case with n = sqrt(9)=3, is not a solution. The case with m=4pi neither.
The last case is m = 6/2=3, integer, so neither works.
So, it is the one with m=6/5 and sqrt(2)
Answer:
12x-21
Step-by-step explanation:
3/4(16x-27-1)
3/4(16x-28)
12x-21
