What is the value of a in the equation 5a – 10b = 45, when b = 3?

andriy [413]

To get the answer we have to substitute b=3 and solve it.
5a-10b=45
5a-10*3=45
5a-30=45 /+30 add 30 both sides
5a-30+30=45+30
5a=75 /:5 divide both sides by 5
5a:5=75:5
a=15 - its the answer

F (x) = 5x – 4, g(x) = x2 + 3x – 8 Evaluate g( f(x) ) for x = 3. g( f (3)) = g

fenix001 [56]

$f\left( x \right) =\quad 5x-4\\ g\left( x \right) =\quad { x }^{ 2 }+3x-8\\ g\left( f\left( x \right) \right)$
for x=3

$f(3)=\quad 5\cdot 3-4\\ f(3)=15-4\\ f(3)=11\\ g(f(3))=g(11)\\ g(11)=\quad { 11 }^{ 2 }+3\cdot 11-8\\ g(11)=\quad 121+33-8\\ g(11)=146$

I hope this was what you asked for.
