Answer:

-80

Step-by-step explanation:

We have: -6 = $\frac{x}{8}$ + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.

The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.

Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:

-6 - 4 = $\frac{x}{8}$ + 4 - 4 ⇒ -10 = $\frac{x}{8}$

Then, multiply by 8 on both sides:

-10 * 8 = $\frac{x}{8}$ * 8 ⇒ x = -80

Thus, x = -80.

Hope this helps!

Step-by-step explanation:

$\tt{} \frac{ \sqrt[3]{60} }{ \sqrt[3]{36} }$

$\tt{} \frac{ \sqrt[3]{5} }{ \sqrt[3]{3} }$

$\tt{} \frac{ \sqrt[3]{5} }{ \sqrt[3]{3} } \times \frac{ \sqrt[3]{ {3}^{2} } }{ \sqrt[3]{ {3}^{2} } }$

$\tt{} \frac{ \sqrt[3]{5} \sqrt[3]{ {3}^{2} } }{ \sqrt[3]{3} \sqrt[3]{ {3}^{2} } }$

$\tt{} \frac{ \sqrt[3]{5 \times {3}^{2} } }{ \sqrt[3]{3 \times {3}^{2} } }$

$\tt{} \frac{ \sqrt[3]{5 \times 9} }{ \sqrt[3]{ {3}^{3} } }$

$\tt{} \frac{ \sqrt[3]{45} }{3}$

$\tt{}1.18563$

What is the common differences or common ratio in the sequence

siniylev [52]

Answer:

Use the formula for Arithmetic only if it is Arithmetic: a1+ (n-1)d

a represents the first number in the sequence, n represents the number, and d represent common difference

Use the formula for geometric sequence: an=a1r the exponent of r to n-1

an represents the nth term you are trying to find, a1 represents the first number, r represents the common ratio, and n-1 is just the nth term minus 1.

Once you figure out if the sequence is arithmetic or geometric you one of those formulas.
