How do you substitute?

Y=x+5

Let's say we are given that x is equal to 5.

Thus, since x=5, we can <em>replace</em> x with the number 5.

So instead of y=x+5, we now have:
y=5+5=

Another example:

x=4+y
where y= 2
x=4+2

What is the next letter? Y B W D U F

Angelina_Jolie [31]

The correct answer is S. The sequence is each alternate letter, changing from one end of the alphabet to the other.

Z Y X W V U T S R Q P L M N O K J I H G F E D C B A
Since we started at the end of the alphabet and then went back to the beginning, there are two letters in the middle that aren't part of the pattern. We only need to worry about which letter is next at the end of the alphabet, though, and the next highlighted letter after U is S.

Hope this helps!

Find RS. See image below

hram777 [196]

Step-by-step explanation:

since both cords are equal, so are arc length

4x + 18 = 7x - 51

3x - 21 = 0

x = 7

arc RS = 4(7) + 18

A) Write the sequence of natural numbers which are multiplied by 3 ?

Volgvan

Answer:

a) 3, 6, 9, 12, 15,..., $3\cdot n$ , b) 4, 7, 10, 13, 16,..., $3\cdot n +1$ , c) Both sequences are arithmetic.

Step-by-step explanation:

a) The sequence of natural numbers which are multiplied by 3 are represented by the function $f(n) = 3\cdot n$ , $n\in \mathbb{N}$ . Let see the first five elements of the sequence: 3, 6, 9, 12, 15,...

b) The sequence of natural numbers which are multiplied by 3 and added to 1 is represented by the function $f(n) = 3\cdot n + 1$ , $n\in \mathbb{N}$ . Let see the first five elements of the sequence: 4, 7, 10, 13, 16,...

c) Both sequences since differences between consecutive elements is constant. Let prove this statement:

(i) $f(n) = 3\cdot n$

$\Delta f = f(n+1) -f(n)$

$\Delta f = 3\cdot (n+1) -3\cdot n$

$\Delta f = 3$

(ii) $f(n) = 3\cdot n +1$

$\Delta f = f(n+1)-f(n)$

$\Delta f = [3\cdot (n+1)+1]-(3\cdot n+1)$

$\Delta f = 3$

Both sequences are arithmetic.

Ema ate 6 slices of pizza. She ate 3/4 of a entire pizza. How many slices of pizza were there in all?

Taya2010 [7]

Divide 6 by $\frac{3}{4}$

$\frac{6}{1}$ ÷ $\frac{3}{4}$

Change $\frac{3}{4}$ to a reciprocal

$\frac{6}{1}$ × $\frac{4}{3}$ = $\frac{24}{3}$

Simplify and your answer is 8
