XY. Electronics can be X and sports Y. Then simply multiply
Answer:
The width is 2x+1
Step-by-step explanation:
10x^2 +5x
Divide this by 5x
10x^2 /5x = 2x
+
5x/5x =1
Add this together
2x+1
The width is 2x+1
To figure out percents you can set it up like:
80/160 = x%/100%
Then cross multiply:
160x = 8000; now divide each side by 160 to isolate x, and you get x = 50%
The answer makes sense, because 80 is half (or 50%) of 160
You can see a definite downward trend as variable x increases. Were you to draw a straight line with neg. slope thru these points, trying to keep the line centered among the points, you'll find that the change in y is roughly -6 when x increases by 8. That gives us the rough slope of -6/8, or -3/4, or -0.75.
Which of the given 2 negative slopes is closer to -0.75?
1 meter = 1/1000 km
1 second = 1/3600 Hour
1m/s = (1/1000)/(1/3600)
1m/s = (1/1000) x (3600/1) = 18/5 = 3.6
so 1 m/s is equivalent to 3.6 km/h
And 60 m/s = 60 x 3.6 = 216 km/h
