If he spent half his savings on supplies and the other half on lunch he shouldn't have money left over. It's a trick question.

The work shows how to use long division to find (x2 + 3x –9) ÷ (x – 2).

Hey!

The first step to solving the rest of this problem would be to distribute the parenthesis in -( 5x - 10 ).

<em>Original Equation :</em>
-( 5x - 10 )

<em>New Equation {Changed by Distributing the Parenthesis} :</em>
- ( 5x ) - ( -10 )

Now we'll simplify the equation.

<em>Old Equation :</em>
- ( 5x ) - ( -10 )

<em>New Equation {Simplified} :</em>
-5x + 10

Okay, now that that part of the equation has been changed, we can add the simplified part to our entire equation.

<em>New Equation :</em>
5x - 9 - 5x + 10

Next we need to group like terms.

<em>Old Equation :</em>
5x - 9 - 5x + 10

<em>New Equation {Changed by Grouping Like Terms} :</em>
5x - 5x - 9 + 10

And now we add the similar elements.

<em>Old Equation :</em>
5x - 5x - 9 + 10

<em>New Equation {Changed by Grouping Like Terms} :</em>
-9 + 10

And finally we simply add the numbers.

<em>Old Equation :</em>
-9 + 10

<em>Solution {Old Equation Solved} :</em>
1

<em>So, this means that 5x - 9 - ( 5x - 10 ) is</em> 1.

Hope this helps!

Convert (10111)2 into decimal number system

Eva8 [605]

Answer:

$(10111)_2 = (23)_{10}$

Step-by-step explanation:

$(10111)_2 = (1 \times 2^4) + (0 \times 2 ^3) + (1 \times 2^2) + (1 \times 2) + (1 \times 2^0)$

$= 16 + 0 + 4 + 2 + 1\\=23$
