Answer:
77 children and 186 adults
Step-by-step explanation:
After a LONG time testing out numbers, I finally found two numbers. What I did was used the equation 3x + 5.5y = 1254. I kept filling in two numbers that can add to 263. For example, I filled in the variables with 77 and 186. Like this: 3(77) + 5.5(186) = 1254. 77 times 3 equals 231 and 186 times 5.5 equals 1023. Add those two numbers together to get 1254. So, there were 77 children and 186 adults.
Replace x in the equation with the x value from the ordered pair and see if the y value meets the inequality.
y ≤ 2(-9) -7
y ≤ -18 - 7
y ≤ -25
The y value in the ordered pair is 1, so replace y with 1 and see if the inequality is true:
1 ≤ -25
1 is a positive value and the equation equals a negative value, so this is not true, because 1 is greater than -25.
