Find the value of x needed to make the equation true. 8x – 4 = 13x + 6

Kipish [7]

Answer:

x = -2

Step-by-step explanation:

First, you need to subtract 8x from both sides:

8x – 4 = 13x + 6

-8x -8x

____________

-4 = 5x + 6

Then, subtract 6 from both sides:

-4 = 5x + 6

-6 - 6

________

-10 = 5x

Lastly, divide both sides by 5:

-10 = 5x

-2 = x

Find the sumofthe geometrical progression of five terms, of which the first term is 7 and the multiplier is 7.Verify that the su

777dan777 [17]

Answer:

The sum of first five term of GP is 19607.

Step-by-step explanation:

We are given the following in the question:

A geometric progression with 7 as the first term and 7 as the common ration.

$a, ar, ar^2,...\\a = 7\\r = 7$

$7, 7^2, 7^3, 7^4...$

Sum of n terms in a geometric progression:

$S_n = \displaystyle\frac{a(r^n - 1)}{(r-1)}$

For sum of five terms, we put n= 5, a = 7, r = 7

$S_5 = \displaystyle\frac{7(7^5 - 1)}{(7-1)}\\\\S_5 = 19607$

The sum of first five term of GP is 19607.

Verification:

$2801\times 7 = 19607$

Thus, the sum is equal to product of 2801 and 7.
