I would say t=9w. This is 9 dollars times number of weeks. This will get total cost.

Answer:

Nina would have total expenses and sales $156 after selling 4 necklaces.

Step-by-step explanation:

Let <em>x</em> represent the amount of necklaces made and sold.

The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:

\displaystyle 140 + 4x

Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:

\displaystyle 39x

To break even, the total cost and profit must be equivalent. Hence:

\displaystyle 140 + 4x = 39x

Solve for <em>x: </em>

<em />\displaystyle \begin{aligned} 140 + 4x & = 39x \\ \\ 140 & = 35x \\ \\ x & = 4 \end{aligned}<em />

<em />

Hence, the break even, Nina would need to sell four necklaces.

And the total expenses/profit would be:

\displaystyle \$39(4) = \$156

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.

Tell whether the system has one solution, infinitely many solutions, or no solution. y=1/2x 2y-x=6
Svet_ta [14]
No solution.

2y-x=6 =y=1/2x+3
Since 1/2x does not equal 1/2x+3, this is a false statement and therefore has no solution

Eight white balls and twenty black balls are in a bag. What is the probability of drawing a black ball in one draw?
JulijaS [17]

Answer:

The correct answer is last option

5/7

Step-by-step explanation:

It is given that, eight white balls and twenty black balls are in a bag

<u>To find the probability</u>

From the above data we get,

number of white balls = 8

Number of black balls = 20

total number of balls = 8 + 20 = 28

Probability of getting black ball = number of black ball/Total number of balls

 = 20/28 = 5/7

The correct answer is last option

5/7
