Answer:
45x-95
Step-by-step explanation:
Its 144. you just subtract the 121 from 265.
A community group bought 30 tickets to an amusement park at a total cost of $810. They bought x student tickets for $25 each and y adult tickets for $30 each.
***
let x=number of student tickets bought
30-x=number of adult tickets bought
..
25x+30(30-x)=810
25x+900-30x=810
5x=90
x=18
30-x=12
number of student tickets bought=18
number of adult tickets bought=12
Hope this helps!
Answer:
(0, -6)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
<em>m</em> - slope
<em>b</em> - y-intercept
Step 1: Write standard form
3x - 7y = 42
Step 2: Rewrite in slope-intercept form
- Subtract 3x on both sides: -7y = 42 - 3x
- Divide both sides by -7: y = -6 + 3/7x
- Rewrite: y = 3/7x - 6
Step 3: Find y-intercept
<em>b</em> = -6
Answer:
y = -3x^2/10 + 6x
