They’ve started out with 0yds of course so, -8yds on the first down. They’ve gained 20yds overall in both downs. You’re now trying to find “x”. -8+x=20. To find “x”, you do 20+8 because the 8 is negative and you would lose numbers in order to get 20, so “x” equals 28. Therefore, you’ve gained 28 yds in the second down and lost 8 yds in the first down.
I really, really hoped that helped. It took awhile to figure out, but I’m sure I’ve got it now.
84 is your awnser if i helped i hope im in fourth grade so dont judge
65-9=56
56 divided by 8 is 7
So they will need 7 tents
-7n + 9 because the common difference is -7, so you have -7n, and then by plugging in the term numbers and the values, you find out that you need to add 9 to the -7n, so the answer is -7n + 9
Answer:
x=
y=5-
Step-by-step explanation:
x+y=5
y=5-x
x-y=a
x-(5-x)=a
2x-5=a
2x=a+5
x=
x+y=5
+y=5
y=5-
