1. x=3
2. t=5
3. x=-2
4. y=4
5. x=1
6. y=88
7x - 2 < 10
Add two to each side.
7x - 2 (+2) < 10 (+2)
Your new equation is: 7x < 12
Divide each side by 7.
7x/7 < 12/7
x < 12/7 or 1 and 5/7
Answer:
idkwwwwwwwwwwww
Step-by-step explanation:
Given:
yesterday = 270
today = 216
yesterday's number of tickets sold is the basis of the percent of change. So, 270 is the 100%.
270 - 216 = 54 * value of the change in ticket sales
54/270 = 0.20 x 100% = 20% * percent of change
There was a 20% decrease in ticket sales.
