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

21r-7-r+5=-52 solve for r
malfutka [58]

Answer:

r = - 2.5

r=-2\frac{1}{2}

Step-by-step explanation:

21r - 7 - r + 5 = - 52

20r - 2 = - 52

20r - 2 + 2 = - 52 + 2

20r = - 50

20r ÷ 20 = - 50 ÷ 20

r = - 2.5

What is the Pythagorean Theorem? Please describe it in detaill!!
Anastaziya [24]

Answer:

Answer is below

Step-by-step explanation:

The Pythagorean Theorem states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. This only works on right triangles. The equation for this is a^{2} +b^{2} = c^{2}. A and B are the shorter side lengths, while C is the hypotenuse. Taking the squares of the two shorter sides will equal the square of the hypotenuse.
