First of all, you can move the +2x to the other side:
-11 = -26 - 2x
Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x
Then you can divide both sides by 2:
7.5 = -x
Then you can flip the sides and the signs around:
x = -7.5
No, The answer is not -7, it is -7.5
Hope this helps! :)

Answer:
If they want irregular fractions its
1= 14/4 . 2= 11/2 3= 14/8
4= 21/4 . 5= 27/6 . 6= 125/13
7= 61/9 . 8= 69/9 . 9= 84/8
If they just want the few simplified then
1= 3 1/2
3= 1 3/4
5= 4 1/2
8= 7 2/3
9= 10 1/2
Step-by-step explanation:
1.667
Basically divide the number by 2
Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle
