Answer:
x+1
Step-by-step explanation:
Let x = number of adult tickets, and y = number of children tickets. One equation must deal with the number of tickets, and the other equation must deal with the revenue from the tickets.
Then x + y = 300 is the number of tickets
12x + 8y = 3280 is the revenue from the tickets.
Using the substitution method:
x + y = 300 ⇒ y = 300 - x ⇒ Equation (3)
12x + 8y = 3280 ⇒ 12x + 8(300-x) = 3280 ⇒ x = 220
y = 300 - x ⇒ y = 300-220 ⇒ 80
Therefore 220 adult tickets and 80 children's tickets were sold.
Answer:
r=0.5 or 1/2
Step-by-step explanation:
if you multiply 0.5 to each Xs you can find out why r is 0.5
Answer:
Neither, x can be a negative number as well. If there is context, please post more to the question.
Step-by-step explanation:
Answer:
y= 3/5x + 1
Step-by-step explanation:
Slope intercept form is modeled by the equation y=mx+b.
M = slope, while B = y-intercept.
The y-intercept in this scenario equals (0, 1) or just simply 1.
The slope equals 3/5. This can be found with rise/run or y/x.
