Answer:
a=2
Step-by-step explanation:
12a - 5 = 4a + 11
Subtract 4a from each side
12a-4a - 5 = 4a-4a + 11
8a -5 = 11
Add 5 to each side
8a -5+5 = 11+5
8a = 16
8a/8 = 16/8
a =2
Answer:
54

Hope this helps!
Answer:
The relation between inputs and outputs is given by an equation called the equation of function. Since the outputs are also real values, hence, reasoning by analogy, you may use the arithmetical operation between functions (addition, subtraction, multiplication, division) to produce new functions.
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
