The simplification of the given complex number is 4.70
What are complex numbers?Complex numbers are those numbers that contain the imaginary and the real part.
A Complex value z is written in a rectangular form as z = x+iy where (x, y) is the rectangular coordinates.
r is the modulus of the complex number and θ is the argument
r =√x²+y² and θ = tan⁻¹y/x
We need to simplify the complex number;
(30-50i)/(3-5i)
Therefore,
(30-50i)/(3-5i) x (3+5i)/(3+5i)
(30-50i) (3+5i)/(9 + 25)
90 + 150i - 150i - 250 /34
160/34
4.70

1/3x+5=23 is equation to represent the dogs’ weights and weight of Luisa' dog is 54 pounds.
What is Equation?Two or more expressions with an Equal sign is called as Equation
Let f represent the weight of Luisa’s dog.
Fabiola’s dog is 5 pounds heavier than one-third of the weight of Luisa’s dog.
Luisa' dog weight: x pounds
One-third of the weight of Luisa’s dog: 1/3x pounds
5 pounds heavier than one-third of the weight of Luisa’s dog : 1/3x+5
Fabiola's dos weight: 1/3x+5pounds that is 23 pounds.
1/3x+5=23
Subtract 5 from both sides
x/3=18
x=54 pounds
Hence, 1/3x+5=23 is equation to represent the dogs’ weights and weight of Luisa' dog is 54 pounds.

Answer:
B. 1.2x - 2.4 + 1.2x - 2
Step-by-step explanation:
We have an algebraic expression and are asked which is the equivalent answer when the expression is simplified.
To solve, we need to take notice that some distribution must happen, which is when you multiply a number outside of a parenthesis to the numbers inside the parenthesis. Follow this rule for 0.3(4x - 8) and -0.5(-2.4x + 4)
0.3(4x - 8)
(0.3(4x) - 0.3(8))
1.2x - 2.4
-0.5(-2.4x + 4)
(-0.5(-2.4x) + -0.5(4))
1.2x - 2
Now put these two equations into one strand to get your answer.
1.2x - 2.4 + 1.2x - 2
Answer:
D. 2.4x-4.4
Step-by-step explanation:
0.3(4x-8)-0.5(-2x+4)
1.2x-2.4-0.5(-2.4x+4)
1.2x-2.4+1.2x-2
=2.4x-4.4
A bowl of Pho soup costs $7.25. The cost of the small bowl was $5 and it had 3 ingredients. What was the cost of each ingredient? (each ingredient was the same price).
Answer:
$0.75 for each ingredient
Step-by-step explanation:
Subtract the cost of the bowl from the total cost (7.25 - 5.00 = 2.25)
Then divide 2.25 by 3 (because there are three ingredients) the answer is 0.75 and add the dollar sign!

Answer:
A. The rectangular prism will have a perimeter of 32 centimeters along the base.
Step-by-step explanation:
When your looking for perimeter, you don't use the height, however, you have to take into account the half sized cubes, in order to get an accurate perimeter, you have to multiply everything by it's multiplicative inverse in order to fill everything with the cubes. Thus, the first option makes the most since you have to double the height and length, when you do so, you get 10 10 6 and 6. You then add them together to get 32.
I really hope this makes since and that I didn't get it wrong. Have a good day and Good luck!

Answer:
96 1/4 in.³
Step-by-step explanation:
Convert 3 1/2 to 7/2, 5 to 5/1, and 11/2 stays the same.
Multiply 7/2 x 5/1 x 11/2 straight across to get 385/4.
Divide the numerator by the denominator, in this case it would be 385 divided by 4. Your answer should be 96 with a remainder of 1.
To convert this to a mixed number, 96 becomes your whole number and then the remainder (in this case 1) becomes the numerator and the divisor of the division problem (in this case 4) becomes the denominator. So now you have 96 1/4 in.³

Step-by-step explanation:
A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 35 pounds and each large box of paper weighs 65 pounds. A total of 22 boxes of paper were shipped weighing 1040 pounds altogether. Determine the number of small boxes shipped and the number of large boxes shipped.
HELP PLZ!!!!!
Number of small boxes shipped = 10
Number of large boxes shipped = 12
Step-by-step explanation:
Let x be the number of small boxes
and
y be the number of large boxes
According to the first statement, a total of 22 boxes were shipped
Equation 1 will be:
x+y=22
And
According to 2nd statement, Total weight was 1350 and we know the weight of one small box is 45 and large box is 75
So equation 2 will be:
45x+75y=1350
We will use the substitution method for solving the equation
So from equation 1
Putting the value of x in eqn 2
Putting the value of y in eqn 1
So,
Number of small boxes shipped = 10
Number of large boxes shipped = 12 ..
