The two will add to 90 degress so

6x+17+3x-17=90 combine like terms

9x=90 divide by 9 to isolate the x

x=10

Now sub it into each equation to solve

ABC = 6(10)+17 = 60+17 = 77

CBD = 3(10)-17 = 30-17 = 13

Check = 77+13 = 90 Correct

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

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