I believe the term is "constant".
The 2 angles are vertical angles, which mean they are equal.
Set the two equations to equal and solve for x:
4x + 7 = 5(x-4)
Use distributive property on the right side:
4x + 7 = 5x -20
Add 20 to each side:
4x +27 = 5x
Subtract 4x from each side:
27 = x
X = 27
Answer:
15(3p+4r)
Step-by-step explanation:
45p + 60r
factor out 15
15(3p+4r)
When squaring fractions, both the numerator and the denominator are squared:
12. (4/5)² = 16/25
13. (-5/12)² = 25/144
14. (13/6)² = 169/36
The answer for (1/3)*120 is 40
