First let's put it into decimals. 19.5 pints of ice cream, everyone gets .75 pints.
19.5 divided by .75 is 26 with no remainder
She can serve 26 guests and will not have any leftover.
Answer:
First term a = 41
Step-by-step explanation:
Arithmetic Progression:
Common differences d = -2
![S_{n}=\frac{n}{2}(2a+[n-1]d)\\\\S_{20}=\frac{20}{2}(2a+19*[-2])\\\\](https://tex.z-dn.net/?f=S_%7Bn%7D%3D%5Cfrac%7Bn%7D%7B2%7D%282a%2B%5Bn-1%5Dd%29%5C%5C%5C%5CS_%7B20%7D%3D%5Cfrac%7B20%7D%7B2%7D%282a%2B19%2A%5B-2%5D%29%5C%5C%5C%5C)
= 10*(2a - 38)
= 10*2a - 10*38
=20a - 380
![S_{22}=\frac{22}{2}(2a+21*[-2])\\\\](https://tex.z-dn.net/?f=S_%7B22%7D%3D%5Cfrac%7B22%7D%7B2%7D%282a%2B21%2A%5B-2%5D%29%5C%5C%5C%5C)
= 11 (2a -42)
=11*2a - 11*42
= 22a - 462

22a - 462 = 20a - 380
22a = 20a - 380 + 462
22a = 20a + 82
22a - 20a = 82
2a = 82
a = 82/2
a = 41
First term a = 41
Answer:
B, E and F
Step-by-step explanation:
(1,2) is a solution to the system of equations.


So we are to merge the two equations into one, since both of the equations are equal to y. a = b, b = c therefore, a = c.

We are to isolate x.
![x[tan(72)-tan(55)]=2.2tan(55)](https://tex.z-dn.net/?f=x%5Btan%2872%29-tan%2855%29%5D%3D2.2tan%2855%29)

The value of x is approximately, 1.9047m
Then, substitute the value of x from


y = 5.862m
Round up, then the answer would be D.
