Answer:

<h2><u>20</u></h2>

Step-by-step explanation:

-4 = \frac{r}{20} - 5

⇒ -4 + 5 = \frac{r}{20}

⇒ 1 = \frac{r}{20}

⇒ 1 × 20 = r

⇒ <u>20</u> = r

Hey there!

Let's start by adding 5 to both sides. This eliminates the -5.  

1 = r/20

Now to solve for r we can multiply both sides by 20.

20 = r

Check

-4 = 20/20 - 5

-4 = 1 - 5

-4 = -4

Your answer is r = 20.

Hope this helps!

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 50, 60,72,... Find the 8th term.
Vadim26 [7]

Answer:

179.159

Step-by-step explanation:

Given the sequence :

50, 60, 72,..

The sequence given is a geometric sequence :

For a geometric sequence ;

ar^(n - 1)

a = first term

r = a2 / a1 = 60 / 50 = 1.2

The 8th term ; n =8

a8 = ar^(n - 1)

a8 = 50*1.2^(8 - 1)

a8 = 50*1.2^7

a8 = 50*3.5831808

a8 = 179.15904

a8 = 179.159 (nearest thousandth )

Apply the distributive property to create an equivalent expression.<br><br> (6m – 7). 4=
Savatey [412]

Answer: 24m-28

Step-by-step explanation:

According to the distributive property ,

a(b+c) = ab+ac

(b+c)a = ba+ca , where a, b and c are any arbitrary expressions.

Given expression : (6m-7)\cdot4

By using distributive property , we have

(6m - 7)\cdot 4= (6m)(4)-(7)(4)\\\\= (6)(4)(m)-28 \ \ \ [\text{By associative property}]\\\\=24m-28

Hence, the required equivalent expression is 24m-28.
