SashulF [63]

Answer:

<em>ab+bc+ca=0</em>

Step-by-step explanation:

We are given:

x^a=y^b=z^c

xyz=1

Separating equations:

x^a=z^c

y^b=z^c

Solving the first equation for x:

\displaystyle x=z^\frac{c}{a}

Solving the second equation for y:

\displaystyle y=z^\frac{c}{b}

Substituting in

xyz=1:

\displaystyle z^\frac{c}{a}z^\frac{c}{b}z=1

Adding the exponents:

\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=1

Since 1=z^0:

\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=z^0

The base is z on both sides so we get rid of them:

\displaystyle \frac{c}{a}+\frac{c}{b}+1=0

Multiplying by ab:

bc+ac+ab=0

Reordering:

ab+bc+ca=0

During a business trip, an individual stopped at two rest stops. In the parking lot of the first rest stop, they counted 20 cars
olganol [36]

Answer

given,

on first stop

number of car = 20  and number of trucks = 18

on second stop

number of car = 18  and number of trucks = 10

we need to calculate which rest stop has higher ratio of car to truck.

Rest Stop 1

ratio= r₁ =\dfrac{cars}{trucks}

           r₁ =\dfrac{20}{18}

           r₁ =\dfrac{10}{9}

Rest Stop 2

ratio= r₂ =\dfrac{cars}{trucks}

           r₂ =\dfrac{18}{10}

           r₂=\dfrac{9}{5}

hence, r₂ > r₁

rest stop 2 has more car to truck ratio than rest stop 1
