Solve.

Serggg [28]

Answer:

The solution is (4, 0)

Step-by-step explanation:

Using Linear combination method to solve:

$2d + e = 8\\d - e = 4\\$

Since "e" have the same coefficient in both equation with opposite operator; we will add.

$(2d + d) + (e - e) = (8 + 4)\\3d = 12\\$

Divide both side by coefficient of d which is 3

$\frac{3d}{3} = \frac{12}{3} \\d = 4\\$

Since d = 4; put 'd' into any of the equation to get 'e'

$2d + e = 8\\2(4) + e = 8\\8 + e = 8\\e = 8 - 8\\e = 0\\$

Therefore, the solution is (4, 0)

Goshia [24]

Answer: 188.4 cm

Step-by-step explanation:

Given

the radius of the circle is $r=30\ cm$

Also, circumference is given by $P=2\pi r$

Putting values

$\Rightarrow P=2\times 3.14 \times 30=188.4\ cm$

The circumference of the circle is $188.4\ cm$
