Answer:

Tori = 22    Kai = 88

Step-by-step explanation:

Take 110 and divide by 5. Tori sold one unit, kai sold 4. Five total. 110/5 is Tori's total. Multiply by 4 to get kai's

For this case, we propose a system of two equations with two unknowns.

Let:

x: The variable that represents the number of biscuit boxes sold by Tori Chang

y: The variable that represents the number of biscuit boxes sold by Kai Chang

Between the two they sold 110 boxes of cookies:

x + y = 110

If Kai sold 4 times more boxes of cookies than Tori we have:

y = 4x

We substitute the second equation in the first:

x + 4x = 110\\5x = 110\\x = \frac {110} {5}\\x = 22

Then, Tori Chang sold 22 boxes of cookies.

y = 4x\\y = 4 * 22\\y = 88

Kai Chang sold 88 boxes of cookies.

Answer:

Tori Chang: 22 Boxes

Kai Chang: 88 boxes

Here is them listed..

Green ball 1, red ball 1, white ball

Green ball 1, red ball 2, white ball

Green ball 2, red ball 1, white ball

Answer:

<h2>d : e : f = 4 : 3 : 6</h2>

Step-by-step explanation:

\bold{METHOD\ 1}\\\\6d=8e\qquad\text{divide both sides by 6}\\\\d=\dfrac{8}{6}e\to d=\dfrac{4}{3}e\\\\\text{Substitute it and}\ f=2e\ \text{to the ratio}\ d:e:f:\\\\\dfrac{4}{3}e:e:2e\qquad\text{cancel}\ e\\\\\dfrac{4}{3}:1:2\qquad\text{multiply by 3}\\\\\huge\boxed{4:3:6}

\bold{METHOD\ 2}\\\\6d=8e\qquad\text{divide both sides by 6}\\\\d=\dfrac{8}{6}e\qquad\text{divide both sides by}\ e\neq0\\\\\dfrac{d}{e}=\dfrac{4}{3}\to d:e=4:3\\\\2e=f\qquad\text{divide both sides by 2}\\\\e=\dfrac{f}{2}\to e=\dfrac{1}{2}f\qquad\text{divide both sides by}\ f\neq0\\\\\dfrac{e}{f}=\dfrac{1}{2}\to e:f=1:2\\\\\text{We have}\ d:e=4:3\ \text{and}\ e:f=1:2.

\text{We know}\ \dfrac{1}{2}=\dfrac{1\cdot3}{2\cdot3}=\dfrac{3}{6}\\\\\text{threfore}\ e:f=3:6\\\\\text{Now we have}\\\\\left\begin{array}{ccc}d:e=4:3\\e:f=3:6\end{array}\right\}\large{\boxed{d:e:f=4:3:6}}
