<span>1. </span><span>A penny weighs about 0.1 oz.
Now, we need to find the weights of pennies in pounds
=> always remember that in every 1 oz, there is 0.0625 pounds.
Since 0.1 is 1/10 of 1 oz, we need to find the value of it in pounds.
=> 0.0625 pounds / 10
=> 0.0625 pounds.
Therefore, in 0.1 oz of penny is
equivalent to 0.00625 pounds.
In problem like this, before determining the answer, you need to make sure that
both unit of measurements are the same. If not, then try to convert.</span>
Answer:
Step-by-step explanation:
WE willl solve the question for the following equation 
1. Add 8c on both sides


2. Add 10 on both sides


3. Substract 2c on both sides


4. Divide both sides by 2


Then, the equation is solved.
Check the picture below.
that's the line of x = 12, just a straight vertical line, notice the green line, that's parallel to it, and the red line, that's perpendicular to it.
let's pick two points for each to get their slopes, hmm say for the green one (5,2) and (5,4)

and for the red one hmmm (3,2) and (7,2)
4/9 0.4 444/1000 is the answer to the problem
