Answer:
A pound of salmon costs <u>7 dollars</u>.
Step-by-step explanation:
Let's use a ratio:
pounds : $$$
8 : 56
4 : 28
2 : 14
1 : 7
A pound of salmon costs $7
The correct answer is 18.7.
So I kind of went an indirect way but I can explain it all. I ignored the 15°. The box in the right correct means that angle is 90°. Since a triangle is always 180°, I subtracted 90 and 15 from 180. That gives you 75°. Now that you know that you can use tangent from SOH CAH TOA. So... tan75= x/5 which turns into 5tan75°. Plug that into a calculator and you get 18.66 which rounds to 18.7.
If you need anymore help I'm here. Hope I helped :) Good luck!

A. Infinitely many
Step-by-step explanation:
6x + 35+ 9x = 15 (x + 4) - 25
15x + 35 = 15 x + 60 -25
15x +35= 15x -35
