Answer:
-5
Step-by-step explanation:
-9+x = -14
Add 9 to each side
-9+x+9 = -14+9
x = -5
That means they have a common denominator. Hope this helps!
Answer:
since the sum of interior angles of hexagon is 720 °
you add the known angles
ie 115 +90+145+160
you get 510
subtract it from 720
you get 210
divide 210 by 3
you get 70
angle cde is 140
Hey there!
The difference of a number, w, and 5 will be represented by (w – 5). Twice this would simply multiply this expression by 2, making it 2(w – 5). Finally, just set this expression equal to 2. Your equation is 2(w – 5) = 2.
To solve this, expand the two to the terms in parentheses. Then, solve the rest of the way as you would normally, using addition, subtraction, multiplication, or division to cancel out and move around terms. Remember, what you do on one side must be done to the other!
2(w – 5) = 2
(2*w – 2*5) = 2
(2w – 10) + 10 = (2) + 10
(2w) ÷ 2 = (12) ÷ 2
w = 6
Hope this helped you out! :-)
