√10 · √6 = √(10 · 6) =
= √60 = √(4 · 15) = √(2² · 15) = 2√15
Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5
Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)

Answer:
0.25c
Step-by-step explanation:
.25 is the decimal form of 25%. .25 * c is how you get the amount you don't have to pay on this item.
For example:
.25 * 10= 2.5
10-2.5=$7.5
