We observe that 20 is 4 more than twice 8. This suggests the time is 1 hour and the rates are
... scooter: 20 mi/h
... bicycle: 8 mi/h
_____
You can let b represent the rate of the bicycle in miles per hour. Then we have (for time in hours and distance in miles) ...
... time = distance/speed
... time = 20/(2b+4) = 8/b
... 20b = 8(2b+4) = 16b +32
... 4b = 32
... b = 8
The rate of the bicycle is 8 mph; that of the scooter is 2*8+4 = 20 mph.
The answer is the fraction 12/16 is also part of the pattern
10 or u could do 25 divided by 2.5 is 10
First find the slope, so subtract the y1 and 2 then same thing with x. -7-1=y. -2-(-3)=x. y is -8 and x is 1. divide -8 and 1. which gives you -8. SLOPE is -8. THE FORMULA for slope intercept form is Mx+B=y first insert the numbers then solve. need any more help use the app socratic and photo math
Answer: −14−7
Step-by-step explanation:
(-8x + 2) - (6x +9)
-8x + 2 - 6x - 9
-14x - 7
