Try not to be bored. You can take the attitude that you actually like math, and that you will some day actually be a MathGenius.
t represents an unknown quantity defined by the equation 16 - 2t = 5t + 9.
To find this value, do the following: Add 2t to both sides, and then subtract 9 from both sides. You'll end up with 7t = 7, which yields t = 1.
We call this the "solution" of the equation given.
Answer:
2/9
Step-by-step explanation:
5 dimes and 5 pennies = 10 coins
P( dime) = number of dimes / total
=5/10 = 1/2
keep the dime
4 dimes and 5 pennies = 9 coins
P( penny) = number of penny / total
=4/9
P( dime, keep, penny) = 1/2 * 4/9 = 2/9
(2000 - 150) / 67
27
(3000 - 400) /6
434
(20 - 7) / .75
