the smith family reunion and the jones family reunion both include a visit to a family friendly amuse florida. the smith family pays $ 882.00 for passes for 10 adults and 18 children. the jones family pays passes for 11 adults and 19 children. which equation below can be used to solve for the price of the ad admissions?
a. 882 + 951 = (10a + 11a) + (18c + 19c)
b. 882 - 951 = (10a - 11a) + (18c - 19c)
c. 882 = 10a - 18c; 951 = 11a - 19c
d. 882 = 10a + 18c; 951 = 11a + 19c
solve for x:
5 + 3x - 7(x + 8) = 9 - x
\\(\frac{1}{3}u + 5 = \frac{2}{3u} - 4\\)
solve by substitution:
\\(\

$$\begin{cases} y = 5x - 3 \\\\ -x - 5y = -11 \\end{cases}$$

\\)
solve by substitution:
\\(\

$$\begin{cases} x = 5y - 22 \\\\ 2x - 6y = -24 \\end{cases}$$

\\)
solve by graphing:
solve the system \\(\

$$\begin{cases} y = \\frac{3}{2}x - 3 \\\\ y = 4x + 2 \\end{cases}$$

\\) by graphing.
solve by elimination:
\\(\

$$\begin{cases} 10x + 6y = 20 \\\\ 5x + 3y = 15 \\end{cases}$$

\\)

Explanation:

Answer:

D. \(882 = 10A + 18C\); \(951 = 11A + 19C\)
\(x=-20\)
\(a = - 9\)
