1. Divide the target number of shirts, 12,600 by the company's rate of making the shirts. That is,
number of hours = 12,600 shirts/ (1200 shirts/6 hours)
= 63 hours
2. Determine the number of workdays for them to complete the shirts by dividing 63 hours by 9 hours/workday. This will give us an answer of 7 workdays.

I NEED THE ANSWER FOR THIS TEST PLEASE<br><br> Simplify -5+i/2i<br><br> Show work

LenaWriter [7]

$\dfrac{-5+i}{2i}=\dfrac{-5+i}{2i}\cdot\dfrac{i}{i}=\dfrac{-5i+i^2}{2i^2}=\dfrac{-5i-1}{2(-1)}=\dfrac{5i+1}{2}=\dfrac{1}{2}+\dfrac{5}{2}i$

PLEASE HELP ME!!!!!!!!!

Answer:

(a) (5, -3)

Step-by-step explanation:

The "substitution method" for solving a system of equations requires that you write an expression that can be substituted for a variable in one or more of the other equations in the system.

<h3>Expression to substitute</h3>

The given equations are ...

y = x -8
2x +3y = 1

We notice the first equation gives an expression for y. This is exactly what we want to substitute for y in the second equation.

<h3>Substitution</h3>

When the expression (x-8) is substituted for y in the second equation, you get ...

2x +3(x -8) = 1

This simplifies to ...

5x -24 = 1

<h3>Solution</h3>

This 2-step equation can now be solved in the usual way:

5x = 25 . . . . . . add 24 to isolate the variable term

x = 25/5 = 5 . . . . . divide by the coefficient of x

Note that we now know what the correct answer choice is.

Using the expression for y, we find ...

y = x -8 = 5 -8 = -3

The solution is (x, y) = (5, -3).

The attached graph confirms this solution.
