skad [1K]3 years ago

7 0

Answer: the answer is 7

Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40

7(7)=49 next 49-9= 40

it checks out, so x= 7

Generalize the pattern by finding the nth term.

Veseljchak [2.6K]

Answer:

4n+2

Step-by-step explanation:

The common difference between the terms is 4 which means that the sequence is an arithmetic sequence.

The general formula for arithmetic sequence is:

$a_{n}=a_{0}+(n-1)d$

where a_n is the nth term, a_0 is the first term and d is the common difference between them.

We know that

$a_{0}=6\\d=4$

Putting the value in general formula:

$a_{n}=6+4(n-1)\\a_{n}=6+4n-4\\a_{n}=4n+6-4\\a_{n}=4n+2\\$

So the generalized pattern is 4n+2 ..

(9·20+60)÷4−16+4·(20·5)

neonofarm [45]

$\text {Hello! Let's Solve this Problem!}$

$\text {The First Step is to Solve the Parentheses:}$

$\text {90*20=180+60=240}\\\text {20*5=100}$

$\text {Your new Problem should be: 240/4-16+4+100}$

$\text {The Next Step is to Divide:}$

$\text {240/4=60}$

$\text {Your new Problem should be: 60-16+4*100}$

$\text {The Next Step is to Subtract:}$

$\text {60-16=44}$

$\text {Now the Next Step is to Multiply:}$

$\text {4*100=400}$

$\text {The Final Step is to Add:}$

$\text {44+100=}$

$\text {Your Answer should be:}$

$\fbox {444}$

$\text {Best of Luck!}$
