Answer:

It will take 12.5 days for Alejandra to catch up with Javier and they both will have travelled 800m

Step-by-step explanation:

Alejandra "catching up" implies that they will both have travelled the same distance

Therefore,

Let y represent the distance when Alejandra will catch up with Javier

Since both equations have the same y-value (distance):

24x+500 = 12x+650

24x - 12x = 650 - 500

12x = 150

x = 12.5

It will take 12.5 days for Alejandra to catch up with Javier

Next, put the amount of time into any of the 2 equations to find what the distance is:

24x + 500 = y

24 (12.5) + 500 = y

y = 800

800m is the distance travelled when Alejandra catches up with Javier

You have budgeted $100 to improve your swimming over the summer. At your local pool, it costs $50 to join the swim association a

romanna [79]

Answer: 10

Step-by-step explanation:

Given : The fixed cost to join the swim association = $50

Then , the cost for each swim class = $5

Let x be the numbers of swim classes you can attend with, then we have the inequality below:-

$50+5x\leq100$

To solve this for x , we first subtract 50 on both sides, we get

$5x\leq50$

Now, divide both sides by 5 , we get

$x\leq\dfrac{50}{5}\\\\\Rightarrow\ x\leq10$

Hence, the possible numbers of swim classes you can attend with =10
