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

Using the digits 0 to 9 at most one Time each,fill in the boxes below to write equations whose solution is 1/2
andrezito [222]

Answer:

The equation is 4x + 5 = 2x + 6

Step-by-step explanation:

The solution is \frac{1}{2} means x = \frac{1}{2}

Let us put the coefficient of x in the left hand side = 4 and the coefficient of x in the right hand side = 2

∵ 4x - 2x = 2x

Now we need two numerical terms their difference is 1 like 5 and 6 or 6 and 7 or 7 and 8 or 8 and 9

Let us take 5 and 6

∵ 4x + 5 = 2x + 6

- Subtract 2x from both sides

∴ 2x + 5 = 6

- Subtract 5 from both sides

∴ 2x = 1

- Divide both sides by 2

∴ x = \frac{1}{2}

∴ The solution is  \frac{1}{2}

The equation is 4x + 5 = 2x + 6

7 mark question. The answers on brainly only got me 3 so please help.
Nady [450]

Answer:

See step by step answer

Step-by-step explanation:

the factors are (x+22)(x-10)=0

so x = -22 and 10, but a dimension cannot be negative, so the answer for x is 10 and then if you plug it back in the dimensions are 4 cm, 11 cm and 21 cm.

When you multiply 4 * 11 * 21 = 924, so you know it's correct.
