Answer:

<h2>h + 4</h2>

Step-by-step explanation:

The number of headbands Nikki has is represented by h, since it is an unknown value. To create a solvable equation, we can only have one variable. Since we know that Kristen has 4 more than Nikki has (4 more than h), we can represent this as h + 4, and solve for h. By doing this, we can then add to h to number 4 and determine how mnay headbands Kristen has.

Answer:

A) H+4

Step-by-step explanation:

I do this in a different way, but i'll do it in both

Mine:

30 ÷ 2 = 15

4 ÷ 2 = 2

15+2, 15 -2

17, 13

Kristen Has 17

Yours:

h+(h+4)=30

-4 -4

h+h = 26

2h = 26,

h = 13, Back to the equation, use 13 as a sub. for all the h's

13+(13+4) = 30

13 + 17 = 30

use the explicit formula an = a1 + (n - 1) * d to find the 500th term of the sequence below. 24,30,36,42,48,... A. 3018 B. 3042

marishachu [46]

Answer:

Option A.

Step-by-step explanation:

The given sequence is

24, 30, 36, 42, 48, ...

It is an AP. Here,

First term = 24

Common difference = 30-24 = 6

The given explicit formula for nth term is

$a_n=a_1+(n-1)d$

where, $a_1$ is first term, d is common difference.

Substitute $a_1=24, d=6 \text{ and }n=500$ in the above formula.

$a_{500}=24+(500-1)(6)$

$a_{500}=24+(499)(6)$

$a_{500}=24+2994$

$a_{500}=3018$

The 500th term of the sequence is 3018.

Therefore, the correct option is A.
