Answer:
x+.8x=27
1.8x=27
x=15
4/5(15)=12
So 15 and 12
Step-by-step explanation:
Rewrite as an equation.<span><span><span>log3</span><span>(9)</span>=x</span><span><span>log3</span><span>(9)</span>=x</span></span>Rewrite <span><span><span>log3</span><span>(9)</span>=x</span><span><span>log3</span><span>(9)</span>=x</span></span> in exponential form using the definition of a logarithm. If <span>xx</span> and <span>bb</span> are positive real numbers and <span>bb</span> does not equal <span>11</span>, then <span><span><span>logb</span><span>(x)</span>=y</span><span><span>logb</span><span>(x)</span>=y</span></span> is equivalent to <span><span><span>by</span>=x</span><span><span>by</span>=x</span></span>.<span><span><span>3x</span>=9</span><span><span>3x</span>=9</span></span>Create equivalent expressions in the equation that all have equal bases.<span><span><span>3x</span>=<span>32</span></span><span><span>3x</span>=<span>32</span></span></span>Since the bases are the same, the two expressions are only equal if the exponents are also equal.<span><span>x=2</span><span>x=2</span></span>The variable <span>xx</span> is equal to <span>22</span>.<span>2</span>
Distribute the Negative Sign:
=3p+1+6(p−8)+−1(p+2)
=3p+1+6(p−8)+−1p+(−1)(2)
=3p+1+6(p−8)+−p+−2
Distribute:
=3p+1+(6)(p)+(6)(−8)+−p+−2
=3p+1+6p+−48+−p+−2
Combine Like Terms:
=3p+1+6p+−48+−p+−2
=(3p+6p+−p)+(1+−48+−2)
=8p + −49
