Y is the amount of money in Susan's account after x weeks.
y is also the amount of money in CiCi's account after x weeks.

You want to know the number of weeks, x, it takes for the amounts in the accounts to be equal. You want Susan't y to equal CiCi's y.

Set the equations equal to each other and solve for x.

65 + 23x = 119 + 14x

Subtract 14x from both sides.

65 + 9x = 119

Subtract 65 from both sides.

9x = 54

Divide both sides by 9.

x = 6

Answer: They will have the same amount of money in 6 weeks.

Check
In 6 weeks, x = 6.
Susan: 65 + 23x = 65 + 23 * 6 = 65 + 138 = 203
CiCi: 119 + 14x = 119 + 14 * 6 = 119 + 84 = 203
In 6 weeks, both Susan and CiCi have $203 in their accounts.

So first you make a chart with how much each person had started out with and on the side the week number. For each week add how much each person added to their account. The week they will have the same amount of money is week 7 with the amount of 203 dollars.

Given:

$1. -3 x^{2}\left(4 x^{3}-7\right)\\$2. $(6 x-5)(2 x+3)$\\3. $(3 x-1)\left(x^{2}+5 x-2\right)$$

To find:

The product of the polynomials.

Solution:

1. $-3 x^{2}\left(4 x^{3}-7\right)$ $=-3 x^{2}(4 x^{3}) -3 x^{2}(-7)$

Multiply the numerical coefficient and add the powers of x.

$=-12 x^{5}+21 x^{2}$

2. $(6 x-5)(2 x+3)=6 x(2 x+3)-5(2x+3)$

Multiply each term of first polynomial with each term of 2nd polynomial.

Multiply the numerical coefficient and add the powers of x.

$=12 x^2+18x-10 x-15$

$=12 x^2+8x-15$

3. $(3 x-1)\left(x^{2}+5 x-2\right)=3 x(x^{2}+5 x-2)-1(x^{2}+5 x-2)$

Multiply each term of first polynomial with each term of 2nd polynomial.

Multiply the numerical coefficient and add the powers of x.

$=3x^{3}+15 x^2-6x-x^{2}-5 x+2$

Add or subtract like terms together.

$=3x^{3}+14 x^2-11x+2$

The answer for multiplying polynomials:

$1. -12 x^{5}+21 x^{2}$

$2. \ 12 x^2+8x-15$

$3. \ 3x^{3}+14 x^2-11x+2$

Greg made 27 ounces of potato salad to serve to 10 people at a picnic if each serving is the same size how much potato salad wip

kirza4 [7]

Answer:

Each person will get 2.7 ounces of potato salad.

Step-by-step explanation:

We are given that;

Total ounces of potato salad Greg made = 27 ounces

Number of persons to be served = 10 people

Now, we are told that each serving is the same size, thus it means each person will receive same size of potato salad.

Thus,

the amount received by each person = Total ounces of potato salad Greg made/total number of persons to be served.

So,

the amount received by each peron

= 27/10

= 2.7 ounces

Thus,

Each person will get 2.7 ounces of potato salad.
