First you need to change the mix fraction which is 9 1/6 - 3 7/8 to 55/6 - 31/8. Then you need to find the least common denominator which is 24 so you'd take 55/6 and multiply both the top and bottom by 4 then for 31/8 you multiply the top and bottom by 3 which would give you 220/24 - 93/24 which equals 127/24 which would reduce to 5 7/24
For the first part, the results get quite crazy. I hardly believe that you're supposed to do this by hand, so I'm afraid that there's some typo in the question.
As for the second part, we have
Plug your value for x and you have
We can rewrite the quantity as
Answer:
G=(-4,5)
G=(2*-4,2*5)
G=(-8,10)
Step-by-step explanation:
6% of $22 = 1.32
22 + 1.32 = 23.32 (cost of meal with tax)
20% of 23.32 = 4.66
23.32 + 4.66 = 27.98
Total cost = $27.98
