Answer:

15

Step-by-step explanation:

GH = (BC + FE) /2

9x-3 = (19+ 5x+1) /2

2* (9x-3) = 19+ 5x+1

18 x - 6 = 5x + 20

13x = 26

x = 2

GH = 9*2 - 3 = 15

tatyana61 [14]

Answer:

Step-by-step explanation:

Donna's Rate is $R$

Rico's Rate is $R+2$

$\frac{R}{R+2}=\frac{2}{3}$

Cross-Multiply

$2(R+2)=32$

$2R+4=3R$

$4=R$

Donna's Rate is $R=4$

Rico's Rate is $R+2=6$

$\frac{6(130)}{60} = \frac{130}{10}=13$
