Answer:
Real number 5
Imaginary number 5i
Complex number 2+5i
Step-by-step explanation:
A real number is that number that can be represented on number line
There is no imaginary part in real number
Example of real number is 5
Imaginary number is that in which there is no real part
Example of imaginary number is 5i
When there is a combination of both real and imaginary part then number is called complex number
Example of complex number is 2+5i
The equations and the number of hotdogs and sodas sold are: x+ y = 126 and 2.25x + 1.50y = 225.75 ; 49 hot dogs and 77 sodas.
Two equations can be derived from this question:
2.25x + 1.50y = 225.75 equation 1
x + y = 126 equation 2
Where:
x = number of hotdogs sold
y = number of soda sold
In order to determine the value of y, multiply equation 2 by 2.25
2.25x + 2.25y = 283.50 equation 3
Subtract equation 1 from 3
57.75 = 0.75y
y = 77
Substitute for y in equation 2
x + 77 = 126
x = 49
