No because x=4 and y=-5 and when you plug it in you get 5(4)+2(-5)=8 20+-10=8 and 10= does not work so it is not a possible solution.
Since 30 lights are 40% of them:
30*2= 60
Since 2*40= 80
We still need the 20 percent.
Half of 40= 20.
30/2= 15
So, 15+60= 75
75 is the number of lights on the tree.
I hope this helps!

Answer:
You would divide 132 by 3 to get the unit rate of 44 mph. Then multiply by 4 to get 176 miles in 4 hours
Step-by-step explanation:
5 rows were added to pattern B
The volume V of the workbox can be calculated by the formula:
V=a*b*c where a is the length, b is the width and c is the height.
In our case a=5'', b=31/2'' and c=4''.
When we input the numbers in the formula we get:
V=5*(31/2)*4=310 in³
So the interior volume V of the workbox is V=310 in³.
