Answer: x ≤ -14
Step-by-step explanation:
3 -
x ≥ 10
1) You want to subtract 3 from both sides of the equation: 3 -
x ≥ 10
-3 -3
------------------------
2) Once you subtract 3 from both sides of the equation you'll be able to cancel out 3-3.
3) After, you'll be left with; -
x ≥ 7
4) You'll then want to divide both sides by -
to isolate x.
5) Divide 7 by -
6) X ≥ -14, but then you'll want to flip the inequality since you divided by a negative.
7) X ≤ -14
Answer: The second option (purple model)
Step-by-step explanation: It is that option because there were 80 toys collected which is 100% and then we do not what the 30% is.
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is 
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become

we can arrange this properly to form a quadratic equation by grouping like terms.

solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
