For this case we have to:
x: Be the variable that represents the number of adult rounds
y: Be the variable that represents the number of rounds of children
We want to know for what amount of rounds bingo costs are the same for adults and children.
Adult costs = 2x + 13
Child costs = 3y + 10
Matching:
We want the same number of rounds, x = y:
Thus, for 3 rounds the costs are the same.
Answer:
3
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).

Finding x for
5x + 4x + 45 = 180
1st step is to combine alike terms
9x + 45 = 180
Now subtract 45 from both sides
9x = 135
Now divide by 9
x = 15
