Answer:
The constant of proportionality is the ratio between two directly proportional quantities.
Step-by-step explanation:
Answer:
Step-by-step explanation:
First verify that they are similar by comparing the ratio of known sides
7/5 = 1.4
(7/2)/ (5/2) = 1.4
As these two are identical, we have similar triangles and the third sides will have the same ratio
6/h = 7/5
h = 6(5/7) = 30/7 = 4 2/7
B=brianne present age
c=camila present age
b=3c (brianne is three times as old as camila)
b+4=2(c+4) (four years from now she will be two times as old as Camila)
<span>b + 4 = 2c + 8
b = 2c + 8 - 4
b = 2c + 4
Replace b with 3c
3c = 2c + 4
3c - 2c = 4
c = 4
Camila is four years old.
b+4=2c+8
b=2(4)+4
b=8+4
b=12
Brianne is 12 years old. </span>
