Answer:$33.41
Step-by-step explanation:
I converted the percentages to decimals and subtracted them from 1.
(Btw x stands for the cost before tip and tax)
This was the equation I came up with based on what was given to me;
57.29 = (1-0.085)x + (1-0.2)x
57.29=0.915x + 0.8x
57.29=1.715x
Divide both sides by 1.715 and should get 33.40524781
Since we are rounding to the nearest cent, the answer would be $33.41
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
It would be answer 4 because 14.85 divided by .05 is 297
The circumference of this circle will be 31.42 cm
