Respuesta :
[tex]45c-3*5\sqrt{5} =75[/tex]
[tex]45c-15\sqrt{5} =75[/tex]
[tex]45c=75+15\sqrt{5}[/tex]
[tex]c=\frac{75+15\sqrt{5} }{45}[/tex]
[tex]c=\frac{15(5+\sqrt{5} )}{45}[/tex]
[tex]c=\frac{5+\sqrt{5} }{3}[/tex]
Answer:
3 1/3
Step-by-step explanation:
First, simplify √625 to 25.
Then multiply by three to get 75.
Add 75 to the other side to get 45c = 150.
c = 3 1/3
