Conversion a mixed number -4 3/
4
to a improper fraction: -4 3/4 = -4 3/
4
= -4 · 4 + (-3)/4
= -16 + (-3)/4
= -19/4
Add: 6 + (-19/4)= 6/1
+ (-19/4) = 6 · 4/1 · 4
+ (-19)/4
= 24/4+ (-19/4)=24 + (-19)/4
= 5/4

2 1/8 = -2 1/8
= -2 · 8 + (-1)/8
= -16 + (-1)/8
= -17/8
Add: the result of step No.
2 + (-17/8) = 5/4+ (-17/8) = 5 · 2/4 · 2+ (-17)/8= 10/8+ (-17/8) = 10 + (-17)/8= -7/8

Solve (x+y) if x=-1/2 and y=-3

bixtya [17]

Answer:

$-3\frac{1}{2}$

Step-by-step explanation:

Solve

$(x+y)$

For x=-1/2 and y=-3

substitute the value of x and the value of y in the expression above

$x+y=(-\frac{1}{2})+(-3)$

Remember that

$(+1)(-1)=-1$

$x+y=-\frac{1}{2}-3=\frac{-1-6}{2}=-\frac{7}{2}$

Convert to mixed number

$-\frac{7}{2}=-\frac{6}{2}-\frac{1}{2}=-3\frac{1}{2}$

Find the midpoint of the line segment.

Alik [6]

Answer:

(1, 3)

Step-by-step explanation:

The first endpoint (the one on the left) is (-3, 2). The second endpoint (the one on the right) is (5, 4). To find the midpoint, find the middle of both x and y. To do that, add the values of x and y respectively and divide by 2:

for x-value of midpoint:

(x-value of first endpoint + x-value of second endpoint) / 2

= (-3 + 5) / 2

= 2 / 2

= 1

for y-value of midpoint

(y-value of first endpoint + y-value of second endpoint) / 2

= (2 + 4) / 2

= 6 / 2

= 3
