Hello There!

<u><em>n - d = 0</em></u>

<u><em>5n+10d = 90</em></u>

<u><em>----------------------</em></u>

<u><em>n-d = 0</em></u>

<u><em>n+2d = 18</em></u>

<u><em>-------------------</em></u>

<u><em>Subtract and solve for "d":</em></u>

<u><em>3d = 18</em></u>

<u><em>d = 6 (# of dimes)</em></u>

<u><em>n = d = 6 (# of nickels)</em></u>

1=10^0 into logarithmic form

Tatiana [17]

Answer:

$0 = log_{10} 1$

Step-by-step explanation:

Base for the exponent and for the logarithm are the same!

10^0 is the <u>exponential</u> form where 10 is the base and 0 the exponent

$log_{10} 1$ is the l<u>ogarithm</u> form where 10 is the base

To solve $log_{10} 1 =$ ask the question :

To what power should I raise the base 10 to obtain the number 1 ?

The answer to the power 0 therefore

$log_{10} 1 = 0$

$1 = 10^{0} -is-the- exponential -form\\0 = log_{10} 1 - is -the -logarithmic -form$

Simplify 2(6x-5)+8x-5

The simplification is 20x-15 because 2 times 6x is 12 x and plus the 8 x its 20 then 2 times -5 is -10 plus the other - 5 is -15
