Percentage is a way to express a relation between two numbers as a fraction of 100<span>. In other words, the percentage tells us how one number relates to another. If we know that number A is </span>25%<span> of number </span>B<span>, we know that </span>A<span> to </span>B<span> is like </span>25<span> is to </span>100<span> (one more transformation: </span>A<span> is four times smaller than </span>B<span>). This is Percentage Calculator's lesson on what is percentage.
But in money a percent is how many cents past the dollar the number is.</span>
Answer:
x=2
Step-by-step explanation:
8x-15=-2x+5
8x=-2x+20
10x=20
x=2
Using Heron's formula, 9=6+6+6/2
A=(sqrt)9(9-6)(9-6)(9-6)
A=9(sqrt)3
A=roughly 15.8845 square units
1) 6x - 5y = 5
3x + 5y = 4
9x = 9
x = 9/9
x = 1
So,your final answer is x = 1.
2) It would be: -x - 3y = -12
x + 3y = 12
x = 12 - 3y
So, option B would be your final answer.
Hope this helps!
Answer:
X = 5
Step-by-step explanation:
multiply what is in the ( )
-2 ( -2)
-2 ( 9)
3x -5 +2x -18 = 2
combine like terms
5x -23 = 2
add 23 to both sides
5x = 25
divide 25 by 5
X = 5
