Answer:
(3 + 2x) + (4 – 5x) = 7 - 3x
(3 + 2i) + (4 – 5i) = 7 - 3i
Step-by-step explanation:
In the addition of two binomials you have to add separately each monomial as follows:
(3 + 2x) + (4 – 5x) =
= (3 + 4) + (2x - 5x) =
= 7 - 3x
Analogously, the sum of the complex numbers 3 + 2i and 4 – 5i is made adding the two real parts from one side, and the two imaginary parts from the other side, as follows:
(3 + 2i) + (4 – 5i) =
= (3 + 4) + (2i - 5i) =
= 7 - 3i

Answer:
65038.55
Step-by-step explanation:
First, Let's turn 12.3% into a decimal which is 0.123
Then Multiply 57,915 by 0.123
57,915 × 0.123= 7123.545 Round; 7,123.55
Then Add [Mark up = Add] 57,915 with 7,123.55
57,915 + 7,123.55= 65038.55
Hence, the Answer is 65038.55
X = 23
x + 4x = 115
5x = 115
115/5 = x
23 = x
