Step-by-step explanation:
First you divide 30 by 2 then you get 15. So you just multiply 7 by 15
Answer:

Step-by-step explanation:
The first term is 9.
Term 1 is 9.
Term 2 is 9 - 3.
Term 3 is 9 - 2(3).
Term 4 is 9 - 3(3).
Term 5 is 9 - 4(5)
Notice the pattern in terms 3 through 5. For each term, subtract 1 less than the term number multiplied by 3 from 9.
For term n, you subtract 1 less than n times 3 from 9.
The nth term is 9 - (n - 1) * 3

Now we simplify the expression on the right side.


The expression for the nth term is

Let's see if it works.
n = 1

n = 2

n = 3

n = 4

n = 5

n = 6

As you can see, following this rule fro the nth term, we got the same first siz terms you got above. Our answer is correct.
Answer: 
Answer: x = { 2 ; 3 }
+) x² - 3 = x² - 1 - 2 = (x - 1)(x + 1) - 2
+) x² - 3 is divisible by x-1 but (x -1)(x + 1) is divisible by x-1
=> 2 must be divisible by x-1
=> x - 1 is divisor of 2
=> (x - 1) ∈ {-1; 1; 2; - 2;}
but x > 1 => x - 1 > 0
⇒ x - 1 = {1; 2; }
+) with x - 1 = 1 => x = 2
x - 1 = 2 => x = 3
Step-by-step explanation:
To convert to a decimal, you can do long division, dividing 5 into 4. Or, you can realize 5/4 = 1 and 1/4, = 1.25. 125/100 is easier to see as a decimal. 125/100 = 1 and 25/100.
She’s serving 20% I know this because there are 5 pieces cut evenly! so 100 divided by 5 is 20.
