Answer:
where is the function? where are the equations?
Answer:
The town recreation department ordered 66 baseballs and 24 bats.
Step-by-step explanation:
Let the number of baseball be 'x'.
Also Let the number of bats be 'y'.
Given:
Total items bought = 100
Now we can say that;
Total items bought is equal to sum of number of baseball and number of bats.
Framing in equation form we get;

Also Given:
Cost of each baseball = $4.50
Cost of each bat = $20
Total purchase = $822
Now we can say that;
Total Purchase is equal to to sum of number of baseball multiplied by Cost of each baseball and number of bats multiplied by Cost of each bat.
framing in equation form we get;

Multiplying equation 1 by 4.5 we get;

Now Subtracting equation 3 from equation 2 we get;

Dividing both side by 15.5 we get;

Substituting the value of y in equation 1 we get;

Hence the town recreation department ordered 66 baseballs and 24 bats.
Step-by-step explanation:
First, subtract 3 from 13.67 so we can find out the minutes only and not the minutes along with the monthly bill.
This will come out to be 10.67
Now, we will divide 10.67 by .11
This will come out to be 97.
This means he was billed for 97 minutes on the phone

Please tell me if this is wrong and my most sincere apologies if it is.
Answer:

Step-by-step explanation:
Explicit formulas are used to represent all the terms of the geometric sequence with a single formula.

a is the first term.
r is the common ratio.
r = second term ÷ first term.
3 , - 6 , 12, - 24, 48 ,........
a = 3
r = -6 ÷ 3 = -2
