Answer:

Step-by-step explanation:

Let the number = x

8x - 13 = 4x + 3 Add 13

8x = 4x + 3 + 13 Combine

8x = 4x + 16 Subtract 4x

8x - 4x = 16 Combine

4x = 16 Divide by 4

x = 16/4

$\dfrac{9}{20}x = 29$

$x = 29 \times \dfrac{20}{9}$

$x = \dfrac{580}{9}$

Simon pays $9 for 6 visits to swim at the community pool. He pays $18 for 12 visits to swim. How much does it cost for each visi

sergij07 [2.7K]

Answer:

$1.50

Step-by-step explanation:

If you do cost per quantity you would get $9 over 6 visits. Then you divide both sides by 6 because to get to one by 6 it's 6 so when you divide both sides by 6 you would get 1.5 over 1 and all you do is add a zero because you're dealing with money

Hope this helps :)
