Vesnalui [34]

Answer:

w= -5

Step-by-step explanation:

-2w - 4 = 6

-2w - 4 + 4 = 6 + 4
-2w = 10

Isolate "w":

$\frac{-2w}{-2} = \frac{10}{-2}$

w = -5

Solve: 2x-3= 5(x+ 6)<br> OA. x= -9<br> OB. x=-11<br> OC. x=-3<br> OD. x- 33

alexgriva [62]

Answer: the correct answer is b x=11

Step-by-step explanation:

2x - 3x + 3x = 5x + 30 + 3

2x = 5x + 33

( 2x - 5x = 5x + 33 - 5x

(1/3)-3x = 33x (1/3) Here we divide it but since it is 1/3, it is the same as dividing 3 divided by 11

1x = 11

x=11

If the first 4 terms of an infinite geometric sequence are 150, 120, 96, and 76.8, then the sum of all the terms in the sequence

hammer [34]

The sum of the sequence is 750

<h3>How to determine the sum of the series?</h3>

The series is given as:

150, 120, 96, and 76.8,

Start by calculating the common ratio using:

r = T2/T1

This gives

r = 120/150

r = 0.8

The sum of the series is then calculated as:

$S = \frac{a}{1 - r}$

This gives

$S = \frac{150}{1 - 0.8}$

Evaluate

S = 750

Hence, the sum of the sequence is 750
