Answer:
Step-by-step explanation:
4.
distance=2436-(-1020)=2436+1020=3456 ft
5.
in two turns points=3-4=-1
in 6 turns=-1/2×6=-3 points
6.
-23+40=17
she had 17 dollars balance.
The number of seats sold cannot be negative, so you have
... x ≥ 0, y ≥ 0
The limits on numbers of seats must be observed, so you have
... y ≤ 2000
... x + y ≤ 3000
And the revenue constraint must be met:
... 35x + 50y ≥ 90,000
Together, these inequalties are ...
{x ≥ 0, y ≥ 0, y ≤ 2000, x + y ≤ 3000, 35x + 50y ≥ 90,000}
X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
We dont know how many people were originally in the group.
