(4C2 * 6C1) + (4C3 * 6C0)
nCr = n! ÷ (n-r)!r!
4C2 = 4! ÷ 2!2! = 6
6C1 = 6! ÷ 5!1! = 6
4C3 = 4! ÷ 1!3! = 4
6C0 = 6! ÷ 6!0! = 1
(6 * 6) + (4 * 1)

A high school drama department sold 238 tickets for their performance.
o An adult ticket cost $6.75.
o A student ticket cost $3.50.
o The high school drama department collected $1,252.25 in ticket sales.
How many student tickets were sold?
Answers
Ley y = number of nonstudent tickets
then we know that the total number of tickets is 537
so
x + y = 537
if we multiply the cost of a ticket by the number of tickets we can also get the total $
3.2x + 5.9y = 2185.5
now we have two equations and two unknowns and we can find the value for these unknowns
lets use substitution
x + y = 537 that means that x = 537-y
substitute this value in the second equation
3.2(537-y) + 5.9y = 2185.5
1718.4 - 3.2y +5.9y = 2185.5
1718.4 + 2.7y = 2185.5
2.7y = 2185.5 - 1718.4
2.7y = 467.1
y = 173
x + y =537
x + 173 = 537
x = 364
Answer:
$6.75 + $3.50 = X

Two groups of friends go to a basketball game. Each group plans to share snacks. The first group buys 5 drinks and 6 pretzels for 28$. The second group buys 2 drinks and 4 pretzels for 16$. Creat two equations in standard form you can use to solve this system
Answers
Answer:
the price for one pretzel was $1.75
Step-by-step explanation:
d for drinks
p for pretzel
3d + 3p = 9
3d = 9 -3p
d = 3 - p
replace d = 3 - 9 into 4d + 2p = 8.5
4d + 2p = 8.5
4(3 - p) + 2p = 8.5
12 - 4p + 2p = 8.5
-2p = 8.5 - 12
-2p = -3.5
p = 1.75

Hey There!
The first step of this problem is to find the formula for arc length
[tex]arc-length=2\pi r(\frac{0}{360} )[/tex]
r=raduis
0 = angle
now we just plug in the values
[tex]arc-length=2\pi 10\frac{54}{360} \\2\pi =6.283185307\\6.283185307x10=62.83185307\\62.83185307\frac{54}{360}=9.424777961[/tex]
so the arc length equals 9.424777961
the last step is to round to the nearest hundreth
so your final answer is 9.42
