First step you would have to do would be to times 35 by 12 to see how much you would have to pay for 12 months.
35 x 12 = 420
Then, as you said, you a down payment of 600 so then you'd add.
600 + 420 = 1,020.
So the total cost of the computer would be $1,020.
Answer:
Step-by-step explanation:
Part A
Part B
- 5.50x = 62.50 - 35
- 5.50x = 27.50
- x = 27.50/5.50
- x = 5
Answer:
D. The standard deviation is known and n > 30.
Step-by-step explanation:
- Your sample size is greater than 30.
- Data points should be away from each other.

Answer:
Step-by-step explanation:
The angles are complimentary, so they add to 90
6x + 3 + 7x + 9 = 90 Combine like terms
13x + 12 = 90 Subtract 12 from both sides
13x = 90 - 12 Combine
13x = 78 Divide both sides by 13
x = 6
<A = 6x + 3
<A = 6*6 + 3
<A = 36 + 3
<A = 39
