Answer: A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10.
Step-by-step explanation:
Given equation: 
To find x, divide 0.6 on both sides, we get

Also 
Thus, 
So the best scenario modeled by the above equation is
"A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10."
Answer:
5 batteries.
Explanation:
"How many batteries lasted more than 5 1/2 hours?" which means it's counting not only 5 1/2, but 5 3/4 and 6 1/4
Answer:
56x + 8
Step-by-step explanation:
Answer:
y= -2x-22.
Step-by-step explanation:
1) the slope-interception common form is y=s*x+i, where 's' and 'i' are the slope and interception, unknown numbers;
2) if x₁= -3; y₁= -16, and s=-2, then the equation of the required line can be written in the point-interception form y-y₁=s(x-x₁); ⇔ y+16= -2(x+3);
3) the required equation in slope-interception form is:
y+16= -2x-6; ⇒ y= -2x-22.
