Step-by-step explanation:
6/4 + 2/3 (taking LCM between denominators)
=> 6*3/4*3 + 2*4/3*4
=> 18/12 + 8/12
=> (18 + 8)/12
=> 26/12
=> 13/6
Answer:
A
Step-by-step explanation:
2x² - 12x - 14
2(x² - 6x - 7)
2(x² - 7x + x - 7)
2(x - 7)(x + 1)
Answer:
3,6
Step-by-step explanation:
x+y=9
x-y=-3
Adding these two equations we get 2x = 6, x=3
y=6
Answer:
x = 12.6 pennies
Step-by-step explanation:
total number of coins = 1 + 2+ 4 + 3 = 10 coins
P(penny) =
P(nickels) =
P(dimes) =
P(quarters) =
hence average value of the coin
x = Penny x P(Penny) + nickel x P(nickel) + dimes x P(dimes) + quarters x P(quarters)
nickels = 5 pennies dimes = 10 ; and quarters = 25 pennies

x = 0.1 + 1 + 4 + 7.5
x = 12.6 pennies
hence, the average pennies for the first draw is equal to x = 12.6 pennies
