Answer:

$16.6

Step-by-step explanation:

x is the price of each CD before tax

so 3x + 3.60 = 53.40

3x = 53.40 - 3.60 = 49.80

x = 49.80/3 = 16.6

Nine less than six times a number is -15
Jlenok [28]

Hello!

6 - 9 × y = -15

When "less than" is used you switch the number before it the number after it. While it seems like it would be 9 -6, its actually 6-9

6 - 9 is -3, you can multiply 3 by 5, to get 15. So your answer would be 5

Hope this helps!

What are the solutions to 3x^2 = 8x — 6?
Bond [772]

Answer:

First, let's move all terms to one side,

\sf x^2-8x+6=0

When given this form (ax^2+bx+c=0), there will be two solutions at the end.

1) \sf x=\frac{-b+\sqrt{b^2-4ab} }{2b}

2) \sf x=\frac{-b-\sqrt{b^2-4ab} }{2b}

where, a=1, b=-8, c=6

\sf x=\frac{8+\sqrt{(-8)^2-4\times6} }{2} ,\frac{8-\sqrt{(-8)^2-4\times6} }{2}

Simplify,

\sf x=\frac{8+2\sqrt{10} }{2} ,\frac{8-2\sqrt{10} }{2}

Simplify,

\sf x=4+\sqrt{10}, 4-\sqrt{10}

Hope it helps!

Refer to the given table on air travel. Suppose a flight that arrived at El Centro is selected at random. What is the probabilit
Triss [41]
In probability, you study the chances of an event to happen based on statistics gathered. Probability is always expressed as a part of a whole, thereby in fractions or percentages. From the statistics gathered, it said that 80% of the time, the plane arrives right on schedule in El Centro. That means that the probability of NOT arriving on time is the other portion, which is 20%. Thus, the answer is 20%.
