Answer:

390

Step-by-step explanation:

The formula of sum of arithmetic sequence is \frac{n}{2} (a+Tn)

The number of this series are 2, 4, 6, 8, 10, 12, .  .  .  .  , 60.

The first term ( a ) = 2

The 30th even number is 60

The Tn is the term of the sequence

So the equation is

30/2 x ( 2 + T_{30})

T_{30} = 60

30/2 x ( 2 + 60 )

30/2 x (62)

1860/2

➷ A) (2/7 x 2/7) + (2/7 x 5/7) + (5/7 x 2/7) =

4/49 + 10/49 + 10/49 = 24/49 <== this is the answer

B) (2/7 x 1/6) + (2/7 x 5/6) + (5/7 x 2/6) -

2/42 + 10/42 + 10/42 = 22/42 <== this is the answer

The second answer could be simplified to 11/21 (only write this answer if it wants the simplified version, otherwise write the one above)

Simplify<br>1)5x+3=x+13<br>2)5/2x-1/X =1/6​
Artyom0805 [142]

Step-by-step explanation (Question 1):        

<u>Step 1: (Question 1): Subtract x from both sides.</u>

5x+3=x+13

5x+3−x=x+13−x

4x+3=13

<u>Step 2: (Question 1): Subtract 3 from both sides.</u>

4x+3−3=13−3

4x=10

<u>Step 3: (Question 1): Divide both sides by 4.</u>

4x/4 = 10/4

FIRST ANSWER: x = 5/2

Step-by-step explanation (Question 2):      

<u>Step 1: (Question 2): Multiply by LCM</u>

15x^2 - 6 = x

<u>Step 2: (Question 2): Solve 15x^2</u>

15x^2 - 6 = x:

x = 2/3

x = -3/5

<u>Step 3: (Question 2): Solve</u>

ANSWER: x=0.666667 or x=−0.6

See Attachment 1 for question 1 steps (FULL)

See Attachment 2 for question 2 steps (FULL)

Answer:    

1)   x = 5/2

2)  x=0.666667 or x=−0.6

 

Hope this helps.
