Answer:
The only option 2 which gives the same values for m=1 and m=4 in both the expressions. ∴ Option 2 is correct.
Let
x-------------> number of baseballs
y-------------> number of bats
we know that
x+y=100----------------> x=100-y --------------> equation 1
4.5x+20y=822 ------------------------> equation 2
<span>I substitute 1 in 2
</span>4.5*(100-y)+20y=822----------------> 450-4.5y+20y=822-----> 15.5y=372
y=372/15.5-----------> y=24
x+y=100------------> x=100-24---------> 76
the answer is
number of baseballs are 76
number of bats are 24

Answer:
30/182 = 15/91.
Step-by-step explanation:
<u>PROBABILITY:</u> the likelihood of an event.
There are a total of 14 shirts in the basket.
Of the 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.
The probability of picking a black shirt is 6 in 14, or 6/14.
The probability of picking a white shirt is 8 in 14, or 8/14.
<u>WITHOUT REPLACING:</u> This means that you take one without putting it back. (There will be one less).
6/14 × 5/13 = 30/182.
30/182 = 15/91.
