Answer:
45
Step-by-step explanation:
Set up ratios for 2 similar triangles:
20/28=x/x+18
Cross multiply
28x=20x+360
8x=360
x=45
Well first you would have to do the distributive property... d+4d+ 24=-1. Then you would have to combine like terms. -----> 5d+24=-1------> 24- (-1) =25... now divide 5 from 5 and 25. So d=5... I'm pretty sure this is right...
The value 3 will be entered. It's a positive value to indicate he is not in debt of any kind.
