Original price of the video game = $42
Percentage of discount = 25%
Amount of discount = 42 * (25/100) dollar
= 42 * (1/4) dollar
= (42/4) dollar
= (21/2) dollar
= $ 10.5
Actual sale price of the video game = (42 - 10.5) dollar
= 31.5 dollar
So we come to know that the amount of discount given is $10.5 and the sale price of the video game is $31.5

Answer:
168.
Step-by-step explanation:
H.C.F. = 6 = 2 by 3.
L.C.M. = 280 = 2^3 by 5 by 7.
30 = 2 by 3 by 5.
x = 2^3 by 3 by 7 = 168.
I used the factorisation method.
Answer:
The answer to this question is: B [-2√5]
Step-by-step explanation:
First, Find both numbers that can accommodate with each of the radicals.
√20
10 and 2
5 and 2 and 2
√80
10 and 8
5 and 2 and 4 and 2
5 and 2 and 2 and 2 and 2
After this is what they'll look like.
√5,2,2 - √5,2,2,2,2
Group numbers of pairs
√5,<u>2,2 </u>- √5,<u>2,2</u>,<u>2,2</u>
<u>For every pair, bring out the #'s, but only one survives, and comes out.</u>
2√5 - 4√5
= -2√5
This is your answer! Hope this helped!
