The equations below represent the numbers y of tickets sold after x weeks for two different local music festivals.
y=10x+150: Country Music Festival
y=20x+115 : Pop Music Festival
After how much time have the same number of tickets been sold for both festivals?
Question 2
What is the number of tickets sold at that time?
Answer:
x=3.5
Step-by-step explanation:
if y = y
20x+115=10x+150
-10x -10x
10x+115=150
-115 -115
10x=35
x=3.5

An integer is between -4 and -19. It is twice as far from -4 as it is from -19. What is the integer? SHOW ALL YOUR STEPS**
Answer:
-12
Step-by-step explanation:
use a number line go back 8 spaces from 19 and back from negative 4
Answer:
this integer is -14
Step-by-step explanation:
19-4=15
the distance between -4 and the integer is 2x, the distance between the integer and -19 is x
x+2x=15
3x=15
x=5
-19+x=-19+5=-14
