Okay so first you distribute to both sides(the arrows). then you subtract 5y to both sides and bring everything down. then you subtract 7 to both sides and get -27=9y and divide by 9 to get the y alone .
For this case we have that the generic equation of the line is given by:

Where,
m: slope of the line
b: intersection with the y axis.
Since the line is parallel to PQ, then the slopes are equal.
We have then:

On the other hand we have:

Substituting values we have:
Answer:
The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
Step-by-step explanation:
Here is your answer
Answer:
54π
Step-by-step explanation:
To find the volume of a cylinder, you multiply the area of the base times the height.
The formula for the area of a circle is πr², so the base is 9π units².
Multiplying that by the height (6 units) gives you 54π units³.
25% 6 divided by 24 will give you the percentage of copper in the bar
