Answer:
3a=4.5
Step-by-step explanation:
it says that "a is equal to 3 times b", which translates to a=3b
We can substitute a as 3b in 2a+4b=5
2(3b)+4b=5
multiply
6b+4b=5
add
10b=5
divide by 10
b=1/2
since it's given that a=3b, we can multiply 1/2 by 3
a=3/2
3a is 3 times a, so we can mutiply 3(3/2)=9/2=4.5
Hope this helps!

Answer: D
Step-by-step explanation:
If f(x) = 4x - 2 and g(x) = 2x + 7 then which of the following gives f(g(3))?
g(3) = 2*3+7 = 6+7 = 13
f(g(3))=f(13) = 4* 13 -2= 52 -2 = 50
