Answer:
8
Step-by-step explanation:
12-10=2
10-m=2
m=8
So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original <em>plus</em> the new percent) Simply set it up like so:
SN *120% = $324.00
Now turn the percent into a decimal:
SN * 1.20 = $324.00
Now divide $324.00 by 1.20
SN = $270
The original value of the basketball player's autograph was 270 dollars!
Hope that helps!
The factors of this expression are 34, x, and y.
Answer:
1 - 4/5-(-1/5)
Step-by-step explanation:
1. - 4/5-(-1/5)
= -0.8+0.2 (if there is a minus sign inside and outside of the parenthesis, when we destroy that parenthesis, both the minus signs will be multiplied and becomes a (+).) (Making it to the percentile).
= -0.6
2. - 4/5-1/5
= -0.8-0.2
= -1
3. -(4/5+1/5)
= -(0.8+ 0.2) (Making those to the percentile).
= -(1) = -1 (When we destroy the parenthesis, if there is a minus sign outside the parenthesis, the result will become a minus.)
From the above expressions, we can see that after calculating, the second and third expressions have the same value, i. e. -1. However, the result of the first expression is different, and we get -0.6. So option one is the right choice.
