3x/4-9=27
Common denominator is 4
4(3x/4-9)=4•27
Distributing 4 through parentheses
4•3x/4-(4•9)=(4•27)
3x-4•9=4•27
3x-36=108 add 36
3x=108+36
3x=144 divide by 3
/3 /3
x=144/3
x=48•3/3
x=48 solved for x
Answer:
Step-by-step explanation:
If D can paint the room in 6 hours, in 1 hour she gets 
of the room painted;
If C can paint the room in x hours, in 1 hour she gets 
of the room painted.
It takes 4 hours to paint it together. Setting up the classic work equation gives us
and we need to solve for x. Multiply everything through by the LCM which is 12x:
making our equation simplify to
2x + 12 = 3x and solve for x:
12 = x
C can paint the room alone in 12 hours.
Answer:
The vertex wold be (-3,4).
Step-by-step explanation:
This is because it is the highest point on the parabola. Since the parabola points down, (-3,4) is the highest point, so it is the vertex.
T(n) = 2n + 3
t(5) = 2(5) + 3
t(5) = 10 + 3
t(5) = 13
