Move the decimal to the left 2 spaces. 90% would .90. 74% would be .74. 134% would be 1.34 Got it? It' always the same no matter the percent. 2 spaces to the left.
0.7x - 2 < 5.5
0.7x < 5.5 +2
0.7x < 7.5 Dividing both sides by 0.7
x < 7.5/0.7
x < 10.71.
That's it.
The quotient is 215.
3870/18= 215. The answer of two divided numbers is called the quotient
The difference of two squares factoring pattern states that a difference of two squares can be factored as follows:
So, whenever you recognize the two terms of a subtraction to be two squares, you can factor it as the sum of the roots multiplied by the difference of the roots.
In this case, the squares are obvious: is the square of , and is the square of
So, we can factor the expression as
(the round parenthesis aren't necessary, I used them only to make clear the two terms)
We can simplify the expression summing like terms:
Answer:
1. 1/3 plus 3/6
1/3 is the same as 2/6 so
2/6 plus 3/6 is 5/6
1=5/6
2. 1/4+2/8
2/8 is the same as 1/4 so
1/4 plus 1/4 is 2/4 which is the same as 1/2
2=1/2
