<span>12 is what percent of 30:
Ok let’s try to analyze the problem.
First, this problem is asking us to determine what the percentage of 12 out of
30 is.
=> 30 is equals to 100% of the number
=> 12 is the X% of the number.
Solutions:
=> 12 / 30 = 0.4
now, multiply this with 100% to get the percentage rate of this decimal number.
=> .4 * 100% = 40%
Therefore, 1 is 40% of the number 30.</span>
The answer to your problem is 10m minus 20n or 10m-20n for short.
A= 10
subtract 4 from both sides to get “a” by itself.
Answer:
Triangle- (height × base)/2
Rhombus-(First diagonal×Second diagonal)/2
Trapezoid- (First base+second base)/2×height
N-gon= (Side-2)*180
8x + 3 = 19
Tip: Anytime you have "more than" in statements, you move the number before the last number.
Example: 4 more than x.
x + 4
