Answer:
Step-by-step explanation:
Let the cost of apples be x
<u>Then we have equation:</u>
- (9 - 1.5)x = 15
- 7.5x = 15
- x = 15/7.5
- x = 2
<u>Cost of apple:</u> $2 per pound
The answers are:
5. 24v-80
6. 18x+12y-30
7. <span>b. c=12π, a=36π
8. a. 16</span><span>÷4
9. c. vertical angles</span>
You can use the letters: a, b, c, d, e, f, g , h, i, and j to make a 5-letter passcode. So you have 10 letters.
For the 1st place you can use 10 letters, for the 2nd you can use 9 ( because the repetition of letters is not allowed ) and so on.
Therefore: 10 * 9 * 8 * 7 * 6 = 30,240
It is also known as a variation of m elements choose n ( V m,n ):
V (10, 5 ) = m * ( m - 1 ) *...* ( m - n + 1 ) = 10 * 9 * 8 * 7 * 6 = 30,240
Answer: You can make a passcode in 30,240 ways.
