Find two numbers whose sum is 55 and whose difference is 21?
Let the numbers be x and y x+y=55 and x-y=21 Now since x-y=21 x=21+y. Plug that into the first equation. 21+y+y=55 or 21+2y=55 so 2y=55-21=34 and y =17 Now since 17+x=55, we immediately see that x=38.

What is the next number 3 9 21 39 63?
NB 3,9,21,39,63. We note that #1;The difference between 3 & 9 = 6 #2 ;The difference between 9 & 21 = 12 ( 2 x 6) #3 ; The difference between 21 & 39 = 18 ( 3 x 6) #4 ; The difference between 39 & 63 = 24 ( 4 x 6) So it follows #5 ; The difference between 63 & X = ( 5 x 6 = 30 ) So 63 + 30 = 93 The answer !!!!!

How do you figure the percent of increase from 55 mph to 70 mph?
To find the percent increase from 55 mph to 70 mph, you first calculate the difference between the two speeds: 70 mph - 55 mph = 15 mph. Then, divide this difference by the original speed (55 mph) and multiply by 100 to get the percent increase: (15/55) * 100 ≈ 27.27%.
