From the information given, you know that the theater has 2760 seats and that the students filled 45% of the seats, so to find the quantity of 6th graders that went on the trip, you have to calculate 45% of 2760:
2760*45%=1242
According to this, the answer is that 1242 6th graders went on the trip.
Explanation: The slope-intercept form of the equation has the following formula: y = mx + c where: m is the slope c is the y-intercept
The given is: 17x + 15y = 5
To put it in the slope-intercept formula, we should isolate the y as follows: 17x + 15y = 5 15y = -17x + 5 y = (-17/15) x + (5/15) y = + where: m is the slope = -17/15 c is the y-intercept = 1/3
