Answer:
Yes, the boats are safe to ride.
Step-by-step explanation:
40 (4) + 12 (2) ≤ 500
160 + 24 ≤ 500
184 ≤ 500
184 is less than 500.
because I was not sure if you had 9 adults instead of 2, this is the answer:
40 (4) + 12 (9) ≤ 500
160 + 108 ≤ 500
268 ≤ 500
268 is less than 500
Solve for x for x: x+2y=2
x+2y +-2y=2+-2y (add -2y on both sides.)
x=-2y+2
Substitute : -2y+2 for x in
4x-y=4:
4(-2y+2)-y=4
-9y+8=4 Simplify both sides of the equation.
-9y+8+-8=4+-8 Add -8 to both sides.
-9y=-4
-9/-9=-4-9 Divide both sides by -9
y=4/9
Substitute 4/9 for y in
x=-2y+2
x=-2(4/9)+2
x=10/9
y=4/9,x=10/9
