Cable has 24 pennies he has hafe as many nickels as pennies he has 5 more dimes than nickels he has 6 fewer quarters than dimes
Andreyy89
Pennies (P) = 24
Nickels = 1/2P
Dimes = 1/2P + 5
Quarters = (1/2P + 5) -6

Therefore...

Nickels = 1/2P = 1/2(24)= 12
Dimes = 12 + 5 = 17
Quarters = 17 - 6 = 11

ozzi

Answer:

slope= 11

Step-by-step explanation:

(12,23) = (x1,y1)

Now,

slope(m)= (y2-y1)/(x2-x1)

=(45-23)/(14-12)
