Answer: The equation is 5x = 125
Step-by-step explanation:
A pentagon is a five sided figure so all the side lengths must be equal. And to find the perimeter of a pentagon the you will the five equal side lengths.
So assume we don't know the side lengths so we will represent it by x and the side lengths are 5 so we will have five x's and they will add up to 125 and that could be represent by the equation.
x + x + x + x + x = 125
5x = 125
x = 25
Answer: The number is 500
Step-by-step explanation:
2% of a number is 10 so set up an equation and let x represent that number.
2% of x = 10 of is the same as times
2% * x = 10 Convert 2% to a decimal
0.02x = 10 divide both sides by 0.02
x = 500
so the number is 500
Now check if it true by multiplying 2% by 500
2% of 500
0.02 * 500 = 10
Answer:
Well it's fairly simple the question is asking for you to name the possibility's of terms. These examples include:
J=1 & C=8, J=2 & C=7, J=3 & C=6, J=4 & C=5, J=5 & C=4, J=6 & C=3, J=7 & C=2, and lastly J=9 & C=1.
Step-by-step explanation:
Well, it's pretty self explanatory as you just need to take two terms that will add up to 9 and replace them into their respective places. :D
1.539 divided by 10 which equal to 0.1539
