Answer:
The library has 1,056 crime DVDs.
Step-by-step explanatiion:
Crime : Adventure : Science
11x : 6x : 10x
6x+384=10x
384=4x
x=96
The number of crime DVDs is 11x.
We found that x=96.
So, the number of crime DVDs the library has is equal to 11*96.
11*96=1,056.
Hope this helps!
Answer:
x = 30°
The angles:
- 2x° = 60°
- 3x° = 90°
- x° = 30°
Step-by-step explanation:
Hello!
The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.
Solve the equation:
- 2x° + 3x° + x° = 180°
- 6x° = 180°
- x° = 30°
We can replace 30° for all the angles.
The measures are:
- 2(30°) = 60°
- 3(30°) = 90°
- 1(30°) = 30°
