Answer:
x = 8
Step-by-step explanation:
Assuming the figure is a parallelogram, the diagonals bisect each other. That means ...
3x -11 = x +5
2x = 16 . . . . . . . add 11-x to both sides
x = 8 . . . . . . divide by 2
Answer: 22
Step-by-step explanation:
(7x+5) + (3x-5) + 90 = 180
10x + 90 =180
-90 -90
10x =90

Answer:
7/4 or 1.75
Step-by-step explanation:
Assuming this is a linear function, you can use the slope formula of change in y-values divided by change in x-values. Take your y-values (8 - 1), which is seven. Then take your x-values (6-2), which is equal to 4. Then your slope is just 7/4 or 1.75.
500
Step-by-step explanation:
400 x 1.25 = 500 or just 400x0.25 +400
Answer:
x = -8
Step-by-step explanation:
Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:
9 - 2x = 25.
Isolate the -2x term by subracting 9 from both sides:
-2x = 16
Finally, solve for x by dividing both sides by -2:
x = -16/2, or x = -8
