What is the sum of 1 2/8 + 2 5/8
SVEN [57.7K]
Hey there!

1 + 2 = 3

2/8 + 5/8 . . .

= 7/8 (denominator stays the same)

3 + 7/8 = 3 7/8

The sum of the numbers 1 2/8 and 2 5/8 is 3 7/8.

1 2/8 + 2 5/8 = 3 7/8.

Hope this helps you.
Have a great day!

What is the slope of the line through (1, -1)and (5,-7)<br> Choose 1 answer:
nalin [4]

Answer:

-3/2

Step-by-step explanation:

the formula for slope is y1-y2/x1-x2

where

y1 is the first point's y coordinate

x1 is the first point's x coordinate

y2 is the second point's y coordinate

x2 is the second point's y coordinate

so now we can plug our points in

-1-(-7)/1-5

6/-4

simplify

-3/2

Find the slope of the equation of the line that passes through the given points. through: (0, -3) and (3, 4)
Nadya [2.5K]

Answer:

7/3

Step-by-step explanation:

The slope is found by dividing the difference in the y-coordinates by the difference in the x-coordinates.

Here, the difference in the y-coordinates is: 4 - (-3) = 4 + 3 = 7. The difference in the x-coordinates is: 3 - 0 = 3.

Dividing 7 by 3, we get a slope of 7/3.
