First add up all the bills.
Total = 110.42
Then find the tip percentage by dividing the tip by the total:
17.67/110.42 = 0.16 = 16%
We have the following equation:
3x2 + 7x + 4 = 0
Using the resolver we have:
x = (- b +/- root (b2 - 4ac)) / 2a
Substituting values we have:
x = (- (7) +/- root ((7) 2 - 4 (3) (4))) / 2 (3)
Rewriting:
x = (- 7 +/- root (49 - 48)) / 6
x = (- 7 +/- root (1)) / 6
x = (- 7 +/- 1) / 6
The results are:
x = (- 7 + 1) / 6 = -6/6 = -1
x = (- 7 - 1) / 6 = -8 / 6 = -4/3
Answer:
x = -1
x = -4/3
option C and D
Doesn't it say the answer in that question...
It is asking for the actual cost of the item and it said $1,489
for his set.
Answer:
5m
Step-by-step explanation:
The expression is 5m(1 + 3m + 1) = 5m(3m + 2), which cannot be simpolified further.
