#1 1.5x + 2.5y = 884.50
#2 x + y = 435
Remember, x represents the children and y represents the adult
The first equation represents the cost of tickets, while the second one represents the number of people.
Find x in equation #2 & plug it into equation #1.
(usually choose easiest equation to solve first, but it's your preference)
x + y = 435
x = 435 - y. ***
Use the equation*** above and plug it into equation #2.
Plugging in x, to solve for y:
1.5(x) + 2.5y = 884.50
1.5(435 - y) + 2.5y = 884.50
652.50 - 1.5y + 2.5y = 884.50
(subtract 652.50 from both sides)
-1.5y + 2.5y = 232
y = 232
Solve for x using equation #2 (or whichever you prefer) and plug in y.
x + y = 435
x + 232 = 435
(subtract 232 from both sides)
x = 203
There were 203 children and 232 adults at the pool that day.
Answer:
Step-by-step explanation:
I guess it’s option D.
Cuz we have to find angle K and 140 minus 60 makes 80 so that’s the answer.

Answer: Choice A) -8 , -5 , 0 , 2 , 6
I recommend drawing out a number line. The negative numbers will increase in magnitude as you move from 0 and go to the left. The positive values increase as you expect when going from left to right.
So we'll have -8 to the left of -5 since -8 is smaller than -5. The value -8 is 8 spots to the left of 0; while -5 is 5 spots to the left of 0. The value 0 is at the center of the number line universe so to speak.
