Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%
X is less than two
the graph line goes to the left, indicating the value of x is negative/less than two. It’s not equal to since the circle isn’t filled
