Answer:
a:b = 11:3 and a:b:c = 11:3:2
Step-by-step explanation:
a:b is equal than write a/b. So a/b=11/3 it means a:b = 11:3
b:c is then b/c = 2
For a:b:c the ratio must be maintained. Ratio is equals reasons or divides. We already know a:b is 11:3. What about a:c?
3a=11b then a=11/3 b, b=2c then c=1/2 b hence a/c =22/3 if we pay attention this reason is 2*11/3 so a:b:c is 11:3:2

Answer:
It is not correct.
Step-by-step explanation:
If you plug 4 in for x, you get -2*4+5=13. This simplifies to: -8+5=13. This is an untrue statement since -8+5 is actually -3, not 13.
