How do you solve 4(6x-1)=120 if you're solving for x

Answers

4(6x-1)=120
Multiply the number outside the parenthesis(4) with the numbers inside the parenthesis(6 and -1)
24x-4=120
Add 4 to both sides
24x=124
Divide both sides by 24

3a² . 2a³ find the product

Answers

Answer:

$6a^(5)$ .

Step-by-step explanation:

To multiply exponents, you will need to begin by multiplying the coefficients as normal. In this instance:

3 · 2 = 6.

When multiplying exponents, however, remember that you must ADD the exponents. Therefore:

3a² · 2a³ = $6a^(5)$

Final answer:

The product of 3a² and 2a³ is found by multiplying the coefficients (the numbers in front of 'a') and adding the exponents for 'a'. The result is 6a⁵.

Explanation:

To find the product of 3a² and 2a³, first you multiply the numerical coefficients and then you add the exponents of 'a'. The numerical coefficient for the first expression is 3 and for the second expression it's 2, multiplying these together we get 6. For the powers of 'a', since both 'a' terms in the two expressions are raised to powers (2 and 3), you add these powers together when multiplying, thus a² * a³ = a⁵. So the final answer is 6a⁵.

If a vacuum cleaner costs $248 and the sales tax is 6%, how much will the vacuum actually cost?

Answers

Initial cost of vacuum cleaner is = 248
tax is 6% = 6/100. 248 x 0.06 = 14.88
Thus, final cost of vacuum cleaner is 248 + 14.88 = $262.88
That is one expensive vacuum cleaner

The answer is $262.88

First you need to multiply the 6% from $248
$248x.06%= $14.88

Now you know that 6% of $248 is $14.88

Now you just need to add the $14.88 to the Orignal price of the vacuum $248

$248+$14.88= $262.88 <---- Answer
