Answer:
(x - √7*√x) / (x - 7)
Step-by-step explanation:
I suppose your expression is √x / (√x + √7)
(√x * (√x - √7)) / ((√x + √7) * √x - √7)) = (√x * √x - √7 * √x) / (x - 7)
= (x - √7*√x) / (x - 7)
Mean=5
Step-by-step explanation:
add the numbers given and divide it by the number of numbers given
I think you have already got it - 36.4
Answer:
10mins
Step-by-step explanation:
you can draw a rtd chart for this problem
rate (m/min)| time (mins) | distance (m )
regular: (300/x) | x | 300m
fist 1/4 : (300/x) | 75: (300/x) | 75m
last 3/4: | (300/x)+15 | 225:(300/x + 15) | 225m
then, make an equation for the times:
x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x
// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop
solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer
