Her is the definition of an imaginary number An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. Zero is considered to be both real and imaginary.

number 3 is your answer x<-y+4/2-4
Answer is d = 50.
Step by step. These are vertical angles so the (d + 70) will equal the opposite angle of 120.
Equation is d + 70 = 120.
Solve for d. Subtract 70 from both sides of the equal sign to solve for d.
d + 70 - 70 = 120 - 70
d = 50
Answer:
7
Step-by-step explanation:
x + 8 = 15
Subtracting 8 from both sides,
x = 15 - 8
=> x = 7
