Find the value of x 12x 6x+28 Your answer

Irina18 [472]

Step-by-step explanation:

Hey there!

By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.

So,

2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)

8x + 28°=180°

8x = 180° - 28°

8x = 152°

$x = \frac{152}{8}$

X = 19°

Therefore, X = 19°.

Hope it helps...

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?

KengaRu [80]

Answer:

133 girls

Step-by-step explanation:

Total members = x

Number of boys = $\frac{2}{9}x$

Number of girls = $\frac{2}{9}x +95$

Number of boys + Number of girls = total members

$\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9$

x = 171

Number of boys = $\frac{2}{9}*171$ = 2 * 19 = 38

Number of girls = 38 + 95 = 133
