Help me out here and show work please
marusya05 [52]

Answer:

x = 3, x = 15, x = 12, x = 1

Hope this helps :)

Step-by-step explanation:

1.) 4x - 1 = 2x + 5

    +1          +1

4x = 2x + 6

-2x   -2x

2x = 6

x = 3

2.) 3x - 5 = 2x + 10

+5          +5

3x = 2x + 15

-2x   -2x

x = 15

3.) 4x + 2 + 30 = 8 + 6x

    4x + 32 = 8 + 6x

           -8      -8

       4x + 24 = 6x

       -4x          -4x

          24 = 2x

            x = 12

4.) 4( x - 1) + 5 = 2x + 3

     4x -4 + 5 = 2x + 3

      4x + 1 = 2x + 3

            -1          -1

           4x = 2x + 2

          -2x     -2x

            2x = 2

              x = 1

Anita invested $6000, some at 5% and the rest at 6%. If the yearly income is $337.50, what is the amount invested at each rate?
Pepsi [2]

Let the amount invested with 5% interest be x

Therefore, the amount invested with 6% interest will be (6000-x)

It is given that the total interest earned yearly is $337.5. Thus, the equation of interest will be:

\frac{5}{100}x+\frac{6}{100}(6000-x)=337.5

Multiplying both sides by 100 we get:

5x+6(6000-x)=33750

5x+36000-6x=33750

Subtracting both sides by 36000 we get:

-x=-2250

\therefore x=2250

Thus, the amount invested at 5% is $2250

Therefore, the amount invested at 6% will be $(6000-2250)=$3750
