Answer:

<u>B. </u>a + c = 216

5a + 3c = 902

Step-by-step explanation: This is the correct answer, because a represents adults and c represents children, so a + c = 216 and 216 represents the total  number of people that the money was collected from. So, that would be correct for the first part of the system of equations. Next, 5a represents $5 for each adult, and 3c represents $3 for each child. While, 902 represents the total number of money collected at the park. Therefore the answer a + c = 216    5a+ 3c = 902 is the correct system of equations answer. Hope this helps ^-^.

Four time a number r plus half a number s equals 12. Twice the number r plus one fourth of the numbers s equals 8. What are the
Snezhnost [94]

The system of equations have no solution.

Explanation:

The equations are 4r+\frac{1}{2}s=12 and 2r+\frac{1}{4} s=8

To find the two numbers, let us solve the equations using substitution method.

From the equation 2r+\frac{1}{4} s=8, let us determine the value of r,

$\begin{aligned} 2 r+\frac{1}{4} s &=8 \\ 2 r &=8-\frac{1}{4} s \\ r &=\frac{1}{2}\left(8-\frac{1}{4} s\right) \\ r &=4-\frac{1}{8} s \end{aligned}$

Let us substitute the value of r in 4r+\frac{1}{2}s=12, we get,

$\begin{aligned} 4\left(4-\frac{1}{8} s\right)+\frac{1}{2} s &=12 \\ 16-\frac{1}{2} s+\frac{1}{2} s &=12 \\ 16 &=12 \end{aligned}$

which is not possible.

This means that the system has no solution.
