Nesterboy [21]3 years ago
3 0

Answer:

n = -4/5

Step-by-step explanation:

-3/4 n + 1/8 n= 1/2

use the rules of signs for multiplication

-3/4 n + 1/8 n= 1/2

multiply both sides 8

-6n + n = 4

collect like terms

-5n = 4

divide both sides by -5

n=-4/5

or alternative form

n=-0.8

Walter got a pay check for $367 this week. If he makes 3.2% commission on total sales, what were his total sales?
leva [86]

The total sales of Walter is $11468.75

<u>Solution:</u>

Given that, Walter got a pay check for $367 this week.  

He makes 3.2% commission on total sales,  

We have to find what were his total sales?  

Now, we know that, amount in pay check = 3.2% of total sales.

\begin{array}{l}{367=3.2 \% \times \text { total sales }} \\\\ {\frac{3.2}{100} \mathrm{x} \text { total sales }=367} \\\\ {\text { Total sales }=367 \times \frac{100}{3.2}} \\\\ {\text { Total sales }=114.6875 \times 100} \\\\ {\text { Total sales }=11468.75}\end{array}

Hence, the total sales of walter is $11468.75 .

What of b make y = 2x plus b the same as y=2x? What does that value mean?
WITCHER [35]

Answer:

No

Step-by-step explanation:

The short answer is no. b stands for some number. Once that number is fixed, it does not change. So the equation would look something like

y = 2x + 6  Now if you look at that again, that 6 is fixed.

If you want to put something in for x like x = 5 you get

y = 2(5) + 6

y = 10 + 6

y = 16                   b = 6 did not change.

What does y = 2x equal

y = 2*5

y = 10

10 does not equal 16.

The only exception to what I've written is b = 0. Then both equations mean the same thing. But that is an exception.

Ellen’s dog has a pen that is 32 feet by 33 feet. What is the area of the dog pen? A rectangle with length 3 cubed feet and widt
nignag [31]

Answer:

3^5 = 243 square feet

Step-by-step explanation:

Ellen’s dog has a pen that is 3² feet by 3³ feet. To find its area we follow the next steps:

1. Multiply powers:

A = 3² * 3³

2. Expand each power:

A = (3*3) * (3*3*3)

3. Simplify:

A = 3^5

The <u>addition</u> of the original exponents is the exponent in the power of product. The dog pen has an area of 3^5 square feet.

Montano1993 [528]

Answer:

tip = 16.60, sales tax = 6.77, each should pay 33.21

76.25 * .08875 =  6.77 sales tax

76.25 + 6.77 = 83.02 bill

83.02 * .20 =  16.60 tip

83.02 + 16.60 = 99.62 total bill

99.62 / 3 = 33.21
