D. multiplying by .6 is what you always have left.
120/4 = 30 So the average cost of a lamp is $30
A segment is only a "midsegment" if it connects midpoints. When labels above and below are 9 and 72, it is clearly not a midsegment. However, because it is parallel to the base, segments above and below on one side are proportional to those in similar positions on the other side.
72/9 = 56/(3x -20)
We can multiply by (3x -20)/8 to get
3x -20 = 7
3x = 27
x = 9
Answer: I think you meant (9^3) 6
If I’m not mistaken the answer is
4374 because 9x9x9= 729x6
Hi! We’re going to use the pythagorean theorem to answer this.
3 + x^2 = 8
subtract 3 from 8
x^2=5
take the square root of both sides
x=sqrt5
