Write a number sentence to compare 7.17 and 7.170
yulyashka [42]
Both of these values are the same, so the number sentence would state:

7.17 = 7.170

You can place any number of zeros to the very end on the right side (when there is a decimal point) without changing the value of the number.

7.1700000 = 7.17 also

-6(x+7)=-4x-2<br> How many solutions does it have
geniusboy [140]

Answer:

Equation have Unique solution i.e x=-20

Step-by-step explanation:

Given Equation:

-6(x+7)=-4x-2

Solving the Equation for 'x'.

           -6(x)-6(7)=-4x-2\\\\-6x-42=-4x-2

Adding '4x'  both sides:

             -6x+4x-42=-4x+4x-2\\\\-6x+4x-42=-2\\\\-2x-42=-2

Adding '42' both sides:

               -2x-42+42=-2+42\\\\-2x=40

                        x=\frac{40}{-2} \\\\x=-20

The equation have Unique solution with the value of x=-20
