Answer: You cannot buy it.
Step-by-step explanation:
$450 with a 20% percent discount would be $360
Add in a sales tax of 5.25%, and it amounts to $549 in total.
Since you only have $400, you cannot buy the bike.
Answer:
(x, y) = (-4, 15)
Step-by-step explanation:
The two equations have the same coefficient for y, so you can eliminate y by subtracting one equation from the other. Here the x coefficient is largest for the first equation, so it will work best to subtract the second equation.
(3x +y) -(2x +y) = (3) -(7)
x = -4 . . . . . . . . simplify
Now, we can find y by substituting this value for x.
2(-4) +y = 7
y = 7 +8 = 15 . . . . . add 8 to both sides of the equation
The solution is (x, y) = (-4, 15).
Corresponding angles are 3 and 7, 4 and 8, and 2 and 6.
In probability<span> theory, the </span>law<span> (or formula) of total </span>probability<span> is a fundamental rule relating marginal </span>probabilities<span> to conditional </span>probabilities. It expresses the total probability<span> of an outcome which can be realized via several distinct events. I hope this answers your question! :)</span>
