3x + y = 6<br> 5x - 2y = 10
Eddi Din [679]

Answer:

x=2

y = 0

Step-by-step explanation:

3x + y = 6         -------------(i)

5x - 2y = 10      -------------(ii)

Multiply (i) by 2   ===>   6x +2y = 12

                     (ii)  ===>   <u> 5x - 2y =  10</u>

add   ============>    11x       = 22

                                              x = 22/11

                                              x = 2

Substitute x = 2 in (i)

       3*2 + y = 6

           6 + y = 6

                 y =  6 - 6

                 y = 0

yaroslaw [1]

Answer:

The approximate circumference is 62.8 mm

Step-by-step explanation:

Circumference is basically the perimeter of the circle

Circumference is given by

2 *\pi *r

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm

Substituting the given values, in above equation, we get -

Circumference =

2 *3.14 * 10 \\62.8mm

The approximate circumference is 62.8 mm
