Answer:
3.5x + 2.50y = 1237.50
425 = x + y
Step-by-step explanation:
number of adult tickets: x
number of student tickets: y
3.5x + 2.50y = 1237.50
( value of adult ticket [3.50]* number of adult tickets [x]) + (value of student ticket [2.50] * number of student tickets [y]) = total value (1237.50)
425 = x + y
(number of adult tickets [x]) + (number of student tickets [y]) = total (425)
The 3 angles must add up to 360 degrees
Only 1 and 4 fit the bill.
Point (3,0) is system solution.
<h3>What is inequality?</h3>
A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
We have
y> -2
x + y <4
First inequation:
-5> -2 (incorrect)
Second inequality:
1-5 <4 (correct)
First inequation:
0> -2 (correct)
Second inequality:
0+3 <4 (correct)
First inequation:
-2> -2 (incorrect)
Second inequality:
-1-2 <4 (correct)
First inequation:
5> -2 (correct)
Second inequality:
1+5 <4 (incorrect)
Hence, Point (3,0) is system solution.
