It takes Sara 5 1/2 hours to drive to her aunt's house. She has already driven 3 1/2 hours.
Which of the following equations can be
used to find the amount of time she has left
to drive, x?
a) x - 3 1/2= 5 1/2
b) x + 3 1/2 = 5 1/2
c) X - 5 1/2= 3 1/2
d) x + 5 1/2 = 3 1/2

c) X - 5 1/2= 3 1/2

Step-by-step explanation:

only one that is relating to the question

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
