Find x (4,12), (x,18); slope=3

vodomira [7]

(y - yo) = m.(x - xo)

We have the points (4, 12) and (x, 18) with slope of 3.

(18 - 12) = 3.(x - 4)

6 = 3x - 12

3x = 6 + 12

3x = 18

x = 18/3

x = 6

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

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