Write an addition expression to describe the situation. Then find the sum and explain its meaning. A quarterback is sacked for a loss of 5 yards. On the next play, his team loses 15 yards. Then the team gains 12 yards on the third play.

Expression:

Sum:

Explain:
can som, one say the expression the sum and the explain please

-20 + 12

Step-by-step explanation:

Since they lost -20 yards, and gained 12, that means that -20 + 12 is the addition problem

The sum of it is -8 because if you add them, there will still be a negative number

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
