Plz HELP! A music store has a 30% off all instruments sale. A. A guitar regularly costs $45.What is the discount price?

B. If the regular price of an item is x dollars, what is the discount price in dollars?

The triangles are similar. what is the value of x? show your work.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Is the point (0, 8) on the x-axis or y-axis? how do you know?
