-25=r/3-11 The first step is to combine whole numbers; add 11 to both sides -25+11=r/3 + -11 + 11 -14=r/3 now multiply each term by 3 -14*3= (r/3)3 -42=r r=-42 check your answer -25= -42/3 -11 -25= -14-11 -25=-14 + -11 -25= -25 (tr...

Fractions are difficult for most people.  A fraction is essentially a division problem.  This question is relatively easy (5/3)d-3/2=-1/2 First we must combine like terms; add 3/2 to both sides of the equation. (5/3)d -3/2 + 3/2= -1/2 +3/2 (5/3)d= 2/2 or (5/3)d=1 now...

4/9y=16 Fractions confuse many people.  A Fraction is a division problem.  4/9 is the same as saying 4 divided by 9.  Since multiplication is the opposite of division we can remove the fraction by multiplying 9  to each term [9(4/9y)= 9(16) 9X 4y/9= 4y; 9 X 16 = 144 4y=...

# A skier moving 6.0m/s forward begins to slow down, accelerating at -2.0m/s^2 for 1.5s. What is the skier's velocity at the end of the 1.5s? (answer)

The simplest way to solve this problem is by using the basic acceleration formula  V= at Where V is velocity, a is acceleration, and t= time.  This problem gives an initial velocity an acceleration and a time asking for an ending velocity.  We can find the ending velocity two different...
