There are a total of 63 bikes if the ratio of blue bikes to black bikes is 4 to 5 how many of the bikes are blue
you

28 blue bikes

Step-by-step explanation:

There follows a relatively simple method for solving this problem:

Let c be a counter.  Then 4c + 5c = 63, and 9c = 63.  Thus, c = 7.

Then the number of blue bikes is 4(7) = 28, and the number of black ones is 5(7) = 35.  Note that 28 + 35 comes to 63.

There are 28 blue bikes.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
