Solve the inequality 31<3x + 4

Kipish [7]

Answer:

x > 9

Step-by-step explanation:

31 < 3x + 4

Treat the < sign the same way you do with =

So first minus 4

31 < 3x + 4

-4 -4

27 < 3x

Divide both sides by 3

9 < x

If you want x on the other side just flip the symbol

x > 9

Answer:

3rd option

Step-by-step explanation:

using the rules of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ : nm > n

$\frac{a^{m} }{a^{n} }$ = $\frac{1}{a^{(n-m)} }$ : n > m

$\frac{6a^2b^{-2} }{8a^{-3b^3} }$ ← separate the variables

= $\frac{6}{8}$ × $\frac{a^2}{a^{-3} }$ × $\frac{b^{-2} }{b^3}$

= $\frac{3}{4}$ × $a^{2-(-3)}$ × $\frac{1}{b^{3-(-2)} }$

= $\frac{3}{4}$ × $a^{2+3}$ × $\frac{1}{b^{3+2} }$

= $\frac{3}{4}$ × $a^{5}$ × $\frac{1}{b^{5} }$

= $\frac{3a^{5} }{4b^{5} }$
