Y - 2 = 5/4 ( x - 4 )
or
y = 5x/4 - 3
Carry out the operation in the brackets and then follow the order of operations and then you can figure out the answer.
18 is the solution.
Answer:
Step-by-step explanation:
Let the number at B be x.
We know that distance between two points on the number line is the absolute value of the difference of numbers at those points.
Then distances representing the lengths of segments AB and BC are:
We are given the ratio of segments:
Substitute and solve for x:
- (x - 9)/(13 - x) = 2/3
- 3(x - 9) = 2(13 - x)
- 3x - 27 = 26 - 2x
- 3x + 2x = 26 + 27
- 5x = 53
- x = 53/5
- x = 10.6
Non-proportional because all the dots are scattered I believe a proportional chart will have a straight line please correct me if I’m wrong :)
If they are the sides of rectangle, then it's perimeter would be:
2(l+b) = 2(24.5+31.7) = 2(56.2) = 112.4
