h a bit more problems! :’)
1) -3 ( 3 - x ) = 2x + 5
2) -6 - 9p = + 3p
3) -5 (-4 - a ) = 3a + 8

<u>Solution</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>

>> -3 (3 - x) = 2x + 5

>> -3 × (3 - x) = 2x + 5

>> -9 + 3x = 2x + 5

>> 3x - 2x = 9 + 5

>> x = 14

<u>Solution</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u>

>> -6 - 9p = 3p

>> -9p - 3p = 6

>> -12p = 6

>> p = -1/2

<u>Solution</u><u> </u><u>3</u><u> </u><u>:</u><u>-</u>

>> -5 (-4 - a) = 3a + 8

>> -5 × (-4 - a) = 3a + 8

>> 20 + 5a = 3a + 8

>> 5a - 3a = 8 - 20

>> 2a = -12

>> a = -12 / 2

>> a = -6

<u>Solution</u><u> </u><u>4</u><u> </u><u>:</u><u>-</u>

>> s - 6 = -5s

>> s + 5s = 6

>> 6s = 6

>> s = 6 / 6

>> s = 1

What is the sum of the first five terms of a geometric series with a1 = 6 and r = 1/3? Express your answer as an improper fracti
Likurg_2 [28]

Answer:

  242/27

Step-by-step explanation:

Using the formula for the sum, you can fill in the given values and do the arithmetic.

  Sn = a1·(r^n -1)/(r -1)

  S5 = 6·((1/3)^5 -1)/(1/3 -1) = 6(-242/243)/(-2/3) = 6·(121/81)

  S5 = 242/27

_____

Or, you can write the terms and add them up. The sum is ...

  6 + 2 + 2/3 + 2/9 + 2/27 = (162 +54 +18 +6 +2)/27 = 242/27

Select the correct answer from the drop-down menu. A=-2[-6 4, 3 7, 12 10], B=3[-2 2 8, 8 5 6], 3C=3[-2 8, 2 5, 8 6] and D=-1[-12
max2010maxim [7]

Answer:

A and D are equal

Step-by-step explanation:

Given

A=-2[-6, 4, 3 ,7, 12, 10]

B=3[-2, 2, 8, 8, 5, 6]

3C=3[-2, 8, 2, 5, 8, 6]

D=-1[-12, 8, 6, 14, 24, 20].

Required

The equal matrices

First, we simplify the given expressions

A=-2[-6, 4, 3 ,7, 12, 10]

Open bracket

A= [12, -8, -6 ,-14, -24, -20]

Next:

B=3[-2, 2, 8, 8, 5, 6]

Open bracket

B=[-6, 6, 24, 24, 15, 18]

Next:

3C=3[-2, 8, 2, 5, 8, 6]

Divide by 3

C=[-2, 8, 2, 5, 8, 6]

Lastly:

D=-1[-12, 8, 6, 14, 24, 20].

Open bracket

D=[12, -8, -6, -14, -24, -20].

By comparison:

A = D=[12, -8, -6, -14, -24, -20].
