Answer:

n=5-2p

Step-by-step explanation:

STEP 1: <em>Rewrite the equation as  3 n + 6 p = 15 .</em>

3n+6p=15

STEP 2: <em>Subtract  6 p  from both sides of the equation.</em>

3n=15-6p

STEP 3: <em>Divide each term by  3  and simplify.</em>

n=5-2p

William works at a nearby electronics store. He makes a commission of 6% percent on everything he sells. If he sells a computer
Naddika [18.5K]

Commission earned by William is $ 45.84

<h3><u>Solution:</u></h3>

Given that,

William makes a commission of 6% percent on everything he sells

He sells a computer for $764.00

<em><u>To find: Commission amount of William</u></em>

Given that he makes a commission of 6 % on everything he sells. So he has received a commission of 6 % of $ 764.00

Commission amount of William = 6 % of $ 764.00

a % of b can be written in fraction as \frac{a}{100} \times b

6 \% \text { of } 764=\frac{6}{100} \times 764=0.06 \times 764=45.84

Thus commission earned by William is $ 45.84

If f(x)=2x^3+5√(x-2) complete the following statement, f(6)=
solong [7]

Answer: 442

Step-by-step explanation:

f(x)=2x^3+5\sqrt{(x-2)}

f(6)

Simply replace all the x's in the equation for 6

f(6)=2(6)^3+5\sqrt{(6-2)}\\ f(6)=2(216)+5\sqrt{4}\\ f(6)=432+5*2\\f(6)=432+10\\f(6)=442

Which constant could each equation be multiplied by to eliminate the x variable in this system of equations? 4x + 5y = 62 5x − 3
qwelly [4]

Answer:

Multiply equation 4x+5y=62 by 5 and 5x-3y=22 by 4

Step-by-step explanation:

Given:

Equations are 4x+5y=62,5x-3y=22

To find: constant by which each equation should be multiplied to eliminate the variable x in the given system of equations

Solution:

4x+5y=62...(i)\\5x-3y=22...(ii)

Multiply equation (i) by 5 and (ii) by 4 to get the following equations:

20x+25y=310\\20x-12y=88

On subtracting these equations, we get

(20x+25y)-(20x-12y)=310-88\\\\13y=222

So, the variable x gets eliminated
