Answer:
2×5×8 = 80
80 + 1 = 81
Thus, the total number of students in the camp is 81
Let the number of two-hour lessons be x and the number of one-hour lessons be y; this gives us the equations
2x + y = 25
50x + 30y = 690
To find x and y, we can solve the quadratic equation provided;
from the first equation:
y = 25 - 2x.......i
By substituting equation i into the second equation, we arrive at:
50x + 30(25 - 2x) = 690
50x + 750 - 60x = 690
-10x = -60
So,
x = 6
Thus, we find that the total number of two-hour lessons is 6 hours.
Envision the equation StartFraction x over 5 EndFraction minus 2 = 11, where x denotes the total number of basketball players registered for a new league. What scenario might this equation represent? Think about the number of teams in the league and the players assigned to each team.
