The City Zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bi

Anna11 [10]

Let a and c represent, respectively, the price of an adult and a child ticket. We know that

$\begin{cases}3a+2c=78.94\\2a+3c=75.86\end{cases}$

Multiply the first equation by 3 and the second equation by 2 to get

$\begin{cases}9a+6c=236.82\\4a+6c=151.72\end{cases}$

Subtract the two equations to have

$5a=85.1 \iff a=17.02$

Plug this value in the first equation to get

$3\cdot 17.02+2c=78.94\iff 2c=27.88\iff c=13.94$

Solve 0.7(5x+15)=2.9-(x+3)

Anni [7]

0.7(5x+15)=2.9 -(x+3)
3.5x+10.5=2.9-x-3
3.5x+10.5= -0.1- x
4.5x= -10.6
x= -2.3555...

Check:
0.7(5(-2.3555...) +15) = 2.9 -(x+3)
2.2555... = 2.2555...

Y results from something being multiplied by x , and the values are always proportional to one another. Notice that putting these points into a ratio of x-value to y-value results in 1:3 as a simplified version. So, the constant of proportionality is what x is being multiplied by to get y . In this case, it is 3 . PLEASE MARK A THE BRAIN THINGY
