Answer:
720
Step-by-step explanation:
nPk = n!/(n-k)!
10P3 = 10!/(10-3)! = 10!/7!
= 10·9·8 = 720
Answer:
Step-by-step explanation:
Let the number of computers sold by Joe be represented by variable X
If Jonathan sold 5 times as many computers , it means he sold 5 times X= 5X
Total number of computers sold by both Jonathan and Joe = 78
Hence, X+5X =78
= 6X = 78
Divide both sides by 6 to solve for X;
X = 78/6
X = 13
And 5X = (5* 13) = 65
Therefore, Jonathan sold 65 computers while Joe sold 13
Answer: The answer is the second equation (y = 3x-4 and y = -1/3x - 2)
Step-by-step explanation:
This is because two lines are perpendicular when the slopes of the equations are negative reciprocals from each other.
P divided by 31 is less than to 30 because what p is will be less because when you divide you make something smaller
