4.25 -2.5x = 14.75<br> I need help

shtirl [24]

$\text {Hey! Let's Solve this Equation!}$

$\text {\underline {The First Step is to do Keep Change Change (KCC)}}$

$\text {Keep: 4.25}\\\text {Change: - into +}\\\text {Change: 2.5x into -2.5x}$

$\text {\underline {The Next Step is to Flip the Equation}}$

$\text {Before: 4.25+-2.5x=14.75}\\\text {After: -2.5x+4.25=14.75}$

$\text {\underline {The Next Step is to Subtract 4.25}}$

$\text {-2.5x+4.25-4.25=14.75-4.25=10.5}\\\text {-2.5x=10.5}$

$\text {\underline {The Final Step is to Divide -2.5}}$

$\text {-2.5x/-2.5=10.5/-2.5}$

$\text {Remember that Dividing a Positive to a Negative will Equal a Negative.}$

$\text {Your Answer Would Be:}$

$\fbox {x=-4.2}$

$\text {Best of Luck!}$

Write a recursive rule for the sequence. 7, 6, 13, 19, 32, ...

allsm [11]

Answer:

recursive rule for the given sequence:

$a_n = a_{n-1}+a_{n-2}$ for n > 2

Step-by-step explanation:

Given the sequence:

7, 6, 13, 19, 32, ......

then;

First term $(a_{1})$ = 7

Second term $(a_{2})$ =6

third term $(a_{3})$ = 13 and so on..

You can see that:

$a_3 = a_1+a_2 = 6+7 = 13$

similarly for:

$a_4 = a_2+a_3 = 6+13 = 19$ and so on..

The recursive rule for this sequence is:

$a_n = a_{n-1}+a_{n-2}$ for n > 2
