It would take christian 9 weeks to save the rest of the money.

189-99 =90 (take away the money he has saved already from the goal to see how much money he needs.

90 ÷ 10 = 9

Hai came someone help I too lazy to do it...
baherus [9]

Answer: 4 Cups

I think in order to solve this, you would need to add up the fractions that they used. So it would be,

\frac{1}{4}+\frac{1}{4}+\frac{3}{8}+\frac{3}{8}+\frac{5}{8}+\frac{5}{8}+\frac{5}{8}+\frac{7}{8}   Transform the Expressions

\frac{1+1}{4} +\frac{3+3+5+5+5+7}{8}    Calculate the sum

\frac{2}{4} +\frac{28}{8}    Reduce

\frac{1}{2}+\frac{7}{2}   Transform the Expression

\frac{1+7}{2}   Calculate

\frac{8}{2}  Reduce the Fraction

Help me with this problem that I'm stuck on!
jok3333 [9.3K]
                              4/(x+1) = 3/x + 1/15
Should we make common denominators with everything, we get
           4*15*x / [15x(x+1)] = 3*15*(x+1)/[15x(x+1)] + x(x+1)/[15x(x+1)]
Multiply both sides of the equation by the denominator to cancel them
                                         60x = 45(x+1) + x(x+1)
                                         60x = 45x + 45 + x^2 + x
                       x^2 - 14x + 45 = 0
                               (x-9)(x-5)  = 0
The answer to this question is that the solutions are x=9 and x=5.
