Answer:
12.5%
Step-by-step explanation:
320 divided by 40 = 8
100 divided by 8 = 12.5
100% is 320 dollars, which means that 40 dollars is 1/8 of 320. And 1/8 of 100 is 12.5%
Add like terms
only add x's together
2x+3x=5x
we can't add x's and numbres so
answer is 5x+4
The perimeter of the square is 35.78
The formula for the perimeter of a square using its area is:
P = 4
Why not? Because every math system you've ever worked with has obeyed these properties! You have never dealt with a system where a×b did not in fact equal b×a, for instance, or where (a×b)×c did not equal a×(b×c). Which is why the properties probably seem somewhat pointless to you. Don't worry about their "relevance" for now; just make sure you can keep the properties straight so you can pass the next test. The lesson below explains how I kept track of the properties.
Yes because 84+45 is 129 and 3(28+15) is 129
