Answer:
9
Step-by-step explanation:
You take 3x and subtract it from both sides.
3x-3x+27=6x-3x
You now should have 27=3x. Divide 3 from 27 to get 9 as your total.
I mean like there is a thing called a calculator but it would be like 90555
Step-by-step explanation:
Given points (-1 , -2) and (3 ,10)
First calculating slope
Slope(m) = (y2 -y1) / (x2 - x1)
= ( 10+ 2)/ ( 3 + 1)
= 12 / 4
= 3
Now The equation of line is
y - y1 = m ( x - x1)
y +2 = 3 ( x +1)
y+2 = 3x + 3
y = 3x + 3 -2
y = 3x + 1
answer: The Earth's place in the galaxy was determined largely by an astronomer named Harlow Shapley. Thanks to the regular periods of these stars and their presence in globular clusters, Shapley was able to map the distances to a number of clusters.
