Answer:
60
Step-by-step explanation:area of a triangle half of base which is 12 and half is 6 then times it by 10 and then you get sixty
In this problem, you want to solve for x. To start, add 3 to both sides to isolate the absolute value: l3 -6xl < 2 The absolute value brackets now disappear and you can subtract 3 from both sides: -6x < -1 This next step is the one that is harder to remember; in a normal equation you would simply divide both sides by -6 to solve for x, but since it is an inequality, you have to flip the sign whenever you divide by a negative. So when you divide both sides by -6, you now have: x > 1/6 Hope this helps :)
Let the walker’s speed be W, then the biker’s is W+1.5W=2.5W. Difference in speed is 1.5W. Distance=speed times time, so 12.5=1.5W×1.5=2.25W, and W=12.5/2.25=1250/225=50/9=5.56 mph. The biker’s speed is 2.5W=125/9=13.89 mph to 2 Dec places.
(Note: “1.5 times faster than a walker’s speed” could not reasonably mean the biker’s speed=1.5W because this would give W=16.67 mph, which is very fast for a runner, let alone a walker (!), and a biker’s speed of 25mph.)
