Answer:
x=-17,y=3
Step-by-step explanation:
x+y=-14
x=x
y=x+20
x+(x+20)=-14
2x+20=-14
2x=-14-20
2x=-34
x=-34/2
x=-17
y=-17+20
y=3
The answer is some number between 9 and 10.
Explanation:
√83
is an irrational number. You won't be able to simplify it any further either, since it doesn't have any perfect square factors.
However, you will be able to tell between which two numbers it lies in.
9^2 is 81 and 10^2 is 100
. Therefore, you can say that a certain number between 9 and 10 is 83 when squared.
If you're looking for an exact answer, then it will be 9.11043357914... (I got that using a calculator).
Answer:
This is a 25% decrease
Step-by-step explanation:
percent change = (old - new)/old * 100 %
The new price is 15
The old price is 20
Since the new price is less than the old price, it is a decrease
percent change = (20-15)/20 * 100 %
= 5/20 * 100%
=.25 * 100%
= 25%
This is a 25% decrease
