Answer:10 gallons are needed to paint 15,000 square feet of wall.
Step-by-step explanation:
3,000/2=1,500
15,000/1,500=10 gallons
-3 + 8 would be an option
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

so we're really looking for the equation of a line whose slope is 1/2 and passes through (-4 , 1)

Answer:
C.
Step-by-step explanation:
Recall that the sum of the (3) interior angles of a triangle <em>must</em> equate to 180.
In other words:

Where x is our unknown angle. So, we need to solve for x.
On the left, add 55 and 20:

Subtract 75 from both sides. The left side cancels:

Therefore, the third angle is 105 degrees.
Our answer is C.
