Answer:
The speed of the biker is 15
Step-by-step explanation:
First, you call the speed of the walker x, and the speed of the biker 2.5x.
Then you know that speed times time equals distance, so you set up and equation. You do x times 2, which is 2x, and then 2.5x times 2, which is 5x. Then, since the distance between them is 18 miles, the equation would be 5x-2x=18. You would get 3x=18, and x is 6. So 6 is the speed of the walker, and 6 times 2.5 = 15, so the speed of the biker is 15.
The answer to the question is m = 2
Answer:
X is 70 degrees
Step-by-step explanation:
In a triangle, all the angles add up to 180.
We can set up an equation:
48+62+x=180
x=180-(48+62)
x=70
You need to find what 11% of 4 2/5 is.
You can convert 4 2/5 to 4.4 and 11% to .11
Then just multiply them together
4.4 * .11 = your answer
