in a survey of 600 adults , 15 % did not know how to ride a bike. how many people can ride a bike? plz I don't really understand this thank u for answering the question SHOW UR WORKING OUT

510

Step-by-step explanation:

510 adults can ride a bike out of 600.

We can do this by first taking 15% of 600. To calculate 15% of 600, simply divide the percent (in this case, 15) by 100 and multiply by the number (600). For example, 15 ÷ 100 x 600 = 90, which means the same as 0.15 x 600 = 90.

Now that we know how many adults can't ride a bike, we take 600 and subtract that number from it. So, 600 - 90 = 510, which is how many adults can ride a bike.

Hope this helped! :)

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
