Answer:

x = -5.25 or 21/4

Step-by-step explanation:

When break the bracket out, if there is a minus sign in front of the bracket, when we break it out, the sign inside the bracket would become positive:

67 = 18 - (8x - 7)

67 = 18 - 8x - (-7)

67 = 18 - 8x + 7

67 = 18 + 7 - 8x

67 = 25 - 8x or rewrite for easier look: 25 - 8x = 67

25 - 8x = 67

8x = 25 - 67

8x = -42

Divide both side by 8, we got:

x = -42 / 8

x = -5.25 or 21/4

Hope this helped :3

What is the radius for the circle given by the equation? (Please help gmanyp)

ratelena [41]

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

where

(h, k) - the coordinates of a center

r - the radius

We have:

$(x-2)^2+y^2=14\\\\(x-2)^2+(y-0)^2=(\sqrt{14})^2$

$Answer:\ r=\sqrt{14}\approx3.742$

Viefleur [7K]

The ratio of girls to boys would be 16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)
