Answer:
$ 198
Step-by-step explanation:
450 + 0.06x = 3750
0.06x = 3750 - 450
x = (3300 * 0.06) = 198
x = 198
Answer: Each candy costs and each drink costs
Step-by-step explanation:
We are told Dominic bought 2 drinks and 5 candies, costing a total of :
(1)
Then, we are told Colton bought 8 drinks and 7 candies, costing a total of :
(2)
Now we have a system with two equations ans two unknowns. Let's solve it:
Multiplying (1) by -4:
(3)
Summing (2) and (3):
(4)
Isolating :
(5) This is the cost of each candy
Substituting (5) in (1):
(6)
Isolating :
(7) This is the cost of each drink
Y is 7.5
A easy way to do it is simply graph it or divide it!
For instance, since x=5 is half of x=10, we would just divide 15 by 2 to get Y which is 7.5
5 because 5 is a factor of the two and the greatest common factor.
Cos 60 = 1/2 --> Sin60 = sr(3)/2 = 0.866
Tan60 = 1/sr(3) = 0.577
