the amusement park charges a fee of $7.50 and $0.75 for every ride. the carnival charges a fee of $10.00 and$0.50 per ride. when
andrew11 [14]
A equation to represent this situation is:

0.75x+7.50=0.50x+10.00

Now we have to find x.

Step 1: Subtract 0.5x from both sides.

<span><span><span><span>0.75x</span>+7.5</span>−<span>0.5x</span></span>=<span><span><span>0.5x</span>+10</span>−<span>0.5x</span></span></span><span><span><span>0.25x</span>+7.5</span>=10

</span>Step 2: Subtract 7.5 from both sides.

0.25x+7.5−7.5=10−7.50.25x=2.5

Step 3: Divide both sides by 0.25.

<span><span><span>0.25x/</span>0.25</span>=<span>2.5/<span>0.25

</span></span></span>Answer:

<span>x=<span>10</span></span>
They will cost the same after 10 rides.

Solve for x &amp; y. 30x−42y=−6 and 5x−7y=−1
vladimir1956 [14]
Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:

\frac{30x  - 42y}{6} = \frac{-6}{6} \\ 5x - 7y = -1

That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.

For example, x = 0 and y = \frac{1}{7} would work, but so would x = 1 and y = \frac{6}{7}
