Answer:Hi,
Let the number be x
Twice the number is 2x
Five less than twice the number is 2x-5, which is given as 9
Therefore, 2x-5 = 9
or, 2x = 9+5
or, 2x = 14
or x=7
Thus the number is 7.
Cheers
Step-by-step explanation:
Answer:we know that all 3 sides are equal
so if side =a
then perimeter =3a
therefore
3a=6n-15
a=6n-15/3
a=2n-5
Answer:
The change is a loss of 10 yards, so -10 yards.
Step-by-step explanation:
The total change in yardage after 2 plays is the sum of the yardage of each play.
What lost yardage means?
Lost yardage means negative yardage.
Imagine that in a Buffalo Bills game, Devin Singletary lost 2 yards on his first carry. So his total yardage is -2.
If in the next carry he gets 3 yards, his total yardage is 1. If he loses 1, his total yardage is -3.
First play
Loss of 5 yards.
So the first play counts for -5 yards.
Second play
Loss of 5 yards.
So the second play counts for -5 yards.
Total
-5 - 5 = -10
The change is a loss of 10 yards, so -10 yards.
