30).  35=.15x+3                                             Equation

         32=.15x                                                 Subtract 3 from both sides

         213.3333333=x                                      Divide by 0.15 on both sides

         35=0.15(213.3333333)+3                     Plug in for X

         35=32+3                                                  Distribute 0.15 into 213.33...

         35=35                                                       Simplify
Therefore she can get about 213 pictures. 

31). 226.5= 25(11am-6:30pm)+x                Equation

        226.5=25(7.5)+x                                    Find out how many hours
        
       226.5=187.5+x                                    distribute the 25 into the parenthesis

       39=x                                                          Subtract 187.5 
   
       226.5=25(7.5)+39                               Plug in for x
     
       226.5=187.5+39                                      Distribute 25 into parenthesis

       226.5=226.5                                            simplify
we've established that the one time fee it 39 so
      y=25(8am-1pm)+39                                 Equation

      y=25(5)+39                                               Find amout of hours

      y= 125+39                                                Distribute 25 into 5

      y=164                                                       simplify
therefore the jones family payed $164

What is the quotient (x3 – 3x2 + 5x – 3) ÷ (x – 1)?
11111nata11111 [884]

Answer:

  1. x^2 -2x +3
  2. x^2 +2x +3

Step-by-step explanation:

The quotient in each case can be found by any of several means, including synthetic division (possibly the easiest), polynomial long division, or graphing.

1. The graph shows you the quotient is (x-1)^2 +2 = x^2 -2x +3.

2. The graph shows you the quotient is (x+1)^2 +2 = x^2 +2x +3.

Simplify 6 x 10−7 2 x 105 .
mafiozo [28]

Answer:

-49

Step-by-step explanation:

it would be this because first we would have to figure out what 6*10 is that why we know what to distribute . so once we figure it out , which is 70 . We would then subtract 14 from 70 . Since 7 is right next to 2 we would then multiply it to get to 14. Once we get that you should get 56, from there you would subtract 56 to 105 , and get your answer.
