Answer:
x = +5
Step-by-step explanation:
The triangles ADB and BDC are similar. Thus it is possible to write an equation of ratios and solve it for x:
x 10
----- = -------
10 4x
Cross-multipying, we get:
4x^2 = 100, which yields x = +5
Answer:
G. -5/2
Step-by-step explanation:
First we want to distribute the 6 into q and 3.
6q + 18 = 2(q + 4)
Next distribute the 2 into q and 4.
6q + 18 = 2q + 8
Now the variable needs to be on one side of the equation. Subtract 2q from both sides.
4q + 18 = 8
Isolate the variable. Subtract 18 from both sides.
4q = -10
Divide 4 on both sides.
q = -10/4
We can now simplify this even further. Divide -10/4 by 2/2
q = -5/2
