Question number 1 You are comparing the costs of producing jewelry at two different manufacturers. Company 1 charges $3.25 per p

Assoli18 [71]

The value of x at equal total cost is 266.67

Here, we want to solve the equation to get the x-value that shows the total costs for the two companies are equal

We proceed as follows;

$\begin{gathered} 3.25x\text{ + 400 = 2.50x + 600} \\ 3.25x-2.50x\text{ = 600-400} \\ \\ 0.75x\text{ = 200} \\ \\ x\text{ = }\frac{200}{0.75} \\ x\text{ = 266.67} \end{gathered}$

What is the value of t?

solmaris [256]

Answer:

A) t = -3

Step-by-step explanation:

We have the expression $\frac{(t-12)}{2}=\frac{3t}{2}-3$ and we have to find the value of t.

First we are going to reorder the expression:

$\frac{(t-12)}{2}=\frac{3t}{2}-3\\\\3=\frac{3t}{2}-\frac{(t-12)}{2}\\\\3=\frac{3t-t-(-12)}{2}\\\\3=\frac{2t+12}{2}$

Now we have to multiply each side by 2,

$3=\frac{2t+12}{2}\\\\3.2=\frac{2t+12}{2}.2\\\\6=2t+12$

Subtract (-12) in both sides,

$6=2t+12\\6-12=2t+12-12\\-6=2t$

Divide both sides in 2,

$-6=2t\\\frac{-6}{2} =\frac{2t}{2} \\-3=t$

The answer is option A) t = -3.
