Answer:

(a) \:  -  \frac{1}{2}  + ( -  \frac{3}{4}) \\  \\  -  \frac{1}{2}   -  \frac{3}{4}  \\  \\  -  \frac{2}{4} -  \frac{3}{4}   \\  \\   -  \frac{2 - 3}{4}  =   - \frac{  5}{4}  =  - 1.25 =  - 1 \frac{1}{4}

___o____o____

(b) \: 3 \frac{1}{8}  + ( -  \frac{1}{4} ) \\  \\  \frac{25}{8}  + ( -  \frac{1}{4} ) \\  \\  \frac{25}{8}  -  \frac{1}{4}  \\  \\  \frac{25}{8}  -  \frac{2}{8}  \\  \\  \frac{25 - 2}{8}  =  \frac{23}{8}  = 2.875 = 2 \frac{7}{8}

Answer:

5 5/6

Step-by-step explanation:

Change them into improper fractions.  Multiply the denominator by the whole number and then add the numerator.  Put that number over the denominator.

2 X 3 = 6           3 X 2 = 6

6 + 1 = 7            6 + 1 = 7

7/3                      7/2

New expression:    7/3 + 7/2

Find a common denominator.  Both denominators can go into 6.

14/6 + 21/6 = 35/6

Change this back into a mixed number by dividing.

Answer: 5 5/6

Line segment AB has endpoints A(7, 4) and B(2, 5). Find the coordinates of the point that divides the line segment directed from
mrs_skeptik [129]

Answer:

(23/4, 17/4)

Step-by-step explanation:

The vector from A to B is ...

... V = B - A = (2-7, 5-4) = (-5, 1)

Point P that divides AB the way you want is 1/4 of that from A:

... P = A + (1/4)×V = (7, 4) + (-5/4, 1/4)

... P = (5 3/4, 4 1/4) = (23/4, 17/4)
