2/3 as many tables as chairs means 3/2 as many chairs as tables. So you can make the equation 4t-95=(3/2)t. Solving for t, the amount of tables, gets you 38 and there were originally 4 times that amount of chairs in the hall so there must have been 152 chairs at first.
Answer:
Bob Saves 168$.
Step-by-step explanation:
According to the Question,
- Given That, Amy , bob and hadi saved $1012 altogether.
Thus, A + B + H = 1012 ⇒ Amy saved $85.
So, B + H = 927 ----- Equation 1
- And Hadi saved 3 times as much as the total amount of Amy's and Bob's savings So, H = 3(A + B) ⇒ We Know Amy saved $85.
So, H - 3B = 255 ----- Equation 2
- Now, Subtract Equation 2 from Equation 1, We get
4B = 672 ⇒ B = 168
Bob Saves 168$.
The vertex is at -b/(2A). if you use the foil method it will come out to -(x^2+2x+1)+4. then distribute the negative and simplify the equation (add the four) the equation comes out to be -x^2-2x+3. The vertex is at x=2/(2*-1), which is -1. plug -1 into the original equation to find y, (y=-(-1)^2-2*(-1)+3) which is y=4. so the vertex is at (-1,4). then since the parabola opens down (negative a value) and has a maximum at 4, y is always less than or equal to 4. x is all real numbers as it goes on forever. so b is your answer.
