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.)
The answer is c because you is multpliying
you spent $303.
because 17 times 15 is 255. then 12 times 4 is 48.
255 plus 48 is 303.
1.Each method works differently the angles inside them is what matters.
2. <span> Manipulating algebra tiles can help people solve linear equations
3.</span><span>Distribute each term of the first polynomial to every term of the second polynomial. Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents. But with Integers you multiply two integers with different signs
4.So you know how </span>
A monomial is a number, a variable or a product of a number and a variable.
<span>multiply each term in one polynomial by each term in the other <span>polynomial
Examples:

The answer is: -3y+9z
This is because you simply switch the sign for every number in the parentheses.
Hope this helps!
