I'm assuming this is a system of equations you want solved so,

x = -y + 3

-2(-y+3)+4y = 6
2y - 6 + 4y = 6
6y = 12
y = 2

x + 2 = 3
x = -1

(-1,2)

At a party of 102 people,17 lb of potato salad is served. a. Write and solve an equation to find how many people each pound of p
Novay_Z [31]

Each pound of potato salad serves 6 people and the average number of pounds of potato salad that each person is served will be \frac{1}{6} pound.

<u><em>Explanation</em></u>

At a party of 102 people, 17 pounds of potato salad is served.

<u>a.</u>  Suppose, each pound of potato salad is served to x number of people.

So, 17 pounds of salad is served to (17*x) or 17x number of people. That means......

17x= 102\\ \\ x= \frac{102}{17}=6

So, each pound of potato salad is served to 6 people.


<u>b.</u>  Suppose, the average number of pounds of potato salad that each person is served is  y

So, the total number of pounds of salad, served to 102 people = (y*102) pounds =102y pounds. That means .....

102y= 17\\ \\ y= \frac{17}{102}= \frac{1}{6}

So, the average number of pounds of potato salad that each person is served will be  \frac{1}{6} pound.

Answer...........................
Usimov [2.4K]

Answer:

9.9 years

Step-by-step explanation:

A = P e ^(rt)

Where A is the amount in the account

P is the amount invested

R is the interest rate

t is the time

P = 8500

r =7% = .07

A = 17000

Substituting into the equation

17000=8500 e^(.07t)

Divide each side by 8500

17000/8500=8500/8500 e^(.07t)

2 = e^(.07t)

Take the natural log of each side

ln (2) = ln e^(.07t)

ln(2) = .07t

Divide each side by .07

ln(2)/.07 = .07t/.07

ln(2)/.07 = t

9.902102579=t

Rounding to one decimal place
