7(w+2)+0.5w=5 What is W if the answer is 5?

V125BC [204]

Answer:

The answer to your question is w = 1.2

Step-by-step explanation:

Data

Equation 7(w + 2) + 0.5w = 5

Expand 7w + 14 + 0.5w = 5

Simplify like terms (7w + 0.5w) + 14 = 5

7.5w + 14 = 5

Subtract 14 in both sides

7.5w + 14 - 14 = 4 - 15

Simplify

7.5w = - 9

Divide both side by 7.5 7.5/7.5w = 9/7.5

Simplify

w = 1.2

An owner of a key rings manufacturing company found that the profit earned (in thousands of dollars) per day by selling n number

vovikov84 [41]

Answer:

The number of key rings sold on a particular day when the total profit is $5,000 is 4,000 rings.

Step-by-step explanation:

The question is incomplete.

An owner of a key rings manufacturing company found that the profit earned (in thousands of dollars) per day by selling n number of key rings is given by

$P=n^2-2n-3$

where n is the number of key rings in thousands.

Find the number of key rings sold on a particular day when the total profit is $5,000.

We have the profit defined by a quadratic function.

We have to calculate n, for which the profit is $5,000.

$P=n^2-2n-3=5\\\\n^2-2n-8=0$

We have to calculate the roots of the polynomial we use the quadratic equation:

$n=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\n= \frac{-2\pm\sqrt{4-4*1*(-8)}}{2}= \frac{-2\pm\sqrt{4-32}}{2} = \frac{-2\pm\sqrt{36}}{2} =\frac{-2\pm6}{2} \\\\n_1=(-2-6)/2=-8/2=-4\\\\n_2=(-2+6)/2=4/2=2$
