8/12=2/3=66.667%
(2/3)*126=84 people were happy
126-84=42 people were not happy

You could solve this using a proportion or just by common sense. 

Proportion: 8/12 = x/126

Cross multiply: 12x = 1008

1008/12 = 84

Or the common sense route is just dividing 12 by 8 then multiplying the answer by 126. Either way, you get the same answer. Hope this helps! :)

Write the linear equation in slope-intercept form.<br><br> -6x + y = 19
Aleonysh [2.5K]
Your answer would be y= 6x + 19


You get rid of the variable on the left side by adding it to both sides giving you y = 6x + 19
Hope it helps

Use the coordinate plane to help you identify the length of each leg then use the Pythagorean Theorem to find the length of CD
Nitella [24]

Answer:

CE= 9cm, DE= 5cm, CD= 10.2956cm

Step-by-step explanation:

Let E be the point of the other triangle.

Using Pythagoras' Theorem,

CD= square root symbol (CE^2 + DE^2)

= square root symbol (9^2+5^2)

= 10.2956cm (6 sf)
