Answer:
x=-2
Step-by-step explanation:
5 times (6 plus x) = 20
6 plus x = 4
x = 4 - 6
x = -2
You answer to number six is 45.019
When you decrease 20 to 11,the decrease is 9
the percentage decrease is
(9/20)*100
=9*100/20
=9*5
=45%
The conversion from miles to feet is 1 mile equals 5,280 feet.
So, if we multiply 2 and a half (or 2.5) by 5,280, we get 13,200 feet.
I hope I helped you!
All of these numbers are making me crazy
