Answer:

x = 15

Step-by-step explanation:

3x - y = 18

Let y =27

3x - 27 = 18

Add 27 to each side

3x-27+27 = 18+27

3x = 45

Divide each side by 3

3x/3 = 45/3

x = 15

______________________________

Given,

y=27

Now,

3x-y=18

or,3x-27=18

or,3x=18+27

or,3x=45

or,X=45/3

X=15

The value of X is 15.

Hope it helps

Grace [21]

Answer:

diagram is below
6, 11, 16, 21
s[n] = s[n-1] +5
26, 31, 36

Step-by-step explanation:

a) See below for the next diagram in sequence.

b) The numbers of straws in each diagram are ...

6, 11, 16, 21, ...

c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...

s[1] = 6

s[n] = s[n-1] +5

d) The next three terms of the sequence are ...

..., 26, 31, 36, ...

Beginning with an integer $n,$ Jake goes through the following steps: $\bullet$ 1. Take the reciprocal of the starting number. $

evablogger [386]

Answer: n= 32

Jakes started with 32

Step-by-step explanation:

Let n represent the initial integer.

Step 1: take the reciprocal.

Reciprocal of n = 1/n

Step 2: double the number obtained in step 1

= 2×1/n = 2/n

Step 3: take the reciprocal of the number obtained in step 2.

Reciprocal of 2/n = n/2

Since he ended up with 16

n/2 = 16

n = 2×16 = 32

The graph of y = |2 is shifted to the left by 6 units. What is the equation of the new graph?

Tasya [4]

Answer:

From your question, I am assuming you are talking about an absolute value graph. In this case the answer would be y = |2 + 6|

Step-by-step explanation: Always remember, when you are graphing absolute value graphs:

When you shift left or right, you put the amount you are shifting inside the absolute value sign.

When you are shifting up or down, you put the amount you are shifting outside the absolute value sign.

When shifting left on a graph, you usually think of subtraction. However, when dealing with absolute value graphs, when you are shifting left, you use addition, as you can see in this problem.

The same goes for right. You use subtraction when shifting right, contrary to what you may think.

However, when you go up, you still use addition, and when you shift down, you still use subtraction.

Do alto de um farol cuja altura é de 20 m avista se um navio sob ângulo de depressão de 30°. A que distância , aproximadamente,

Mkey [24]

Esta é a trigonometria . Se você desenhar uma linha a partir do topo da casa de luz para o barco, você terá a hypotonuse de um triângulo. Um truque é lembrar que este é um triângulo especial. É um triângulo 30-60-90 , que tem propriedades especiais mostradas na fixação abaixo . por isso sabemos que o lado adjacente que não é o hyposonuse é x√3 . Agora sabemos que x√3 = 20
Solve for x.
x√3=20
divide both sides by √3.
x=20/(√3)
Try not to have square roots (√) in denomenator so multiply top and bottom by √3 and get
x=(20√3)/3
x is what we are looking for so the answer is 
20√3 m ou cerca de 34.64 m
