To find a percentage of a number we multiply the percentage times the number and get the result, here we have the percentage and the result and need to find out which number it corresponds to, lets write an equation to do so and keep in mind that the percentage itself can be written in a different way:
225% = 225 out of 100 = 225/100
So we have this equation, where we call x the number we are looking for:
<span>(225%)(x) = 81
</span>(225/100)(x) = 81
so we solve for x:
225x = 81*100 = 8100
x = 8100/225
x = 36
The original number is 36, hence 225% of 36 is 81
Answer:
24.5
Step-by-step explanation:
If you multiply 2 and 24.5 together you would get 49
Answer:
I think it would be 350$
Step-by-step explanation:
ok so you have to buy 10 shirts so you need to set up your problem which would be 10(12+8+15)
Then you would have to actually distribute which would give you 120+80+150
Finally you just add all of your numbers together which would be 350$
The answer is (6,-4). By the way, this was very hard to read.
1/2 (8+4)= 6
1/2(-1+4)= 1.5
1/2 (2+4)= 3
1/2 (4+4)= 4
So the correct answer would be A(8)
