# (2u^3-13u^2-8u+7) divided by (u-7)

2u^2

u-7 !2u^3-13u^2-8u+7

2u^3-7u^2

then -6u

u-7 -6u^2 -8u +7

-6u^2 +42u

then -50

u-7 -50u +7

-50u + 350

then a remainder of -343

i don't get algebra

The sum of m and n, divided by the difference of m and n

a party mix is made by combining nuts that sell for $3.50 per lb with raisins that seel for $1.50 per lb. How much of each should be used to get 32 lbs of a mix that will sell for 2.75 per lb?

## To solve algebra word problems, it's important to understand the problem and identify the variables involved. Here's a step-by-step guide to solving the problem you mentioned:

1. Let's assume the amount of nuts used in pounds as "x" and the amount of raisins used in pounds as "y". We need to find the values of x and y.

2. Create an equation based on the given information. The total weight of the mixture is 32 lbs, so we can set up the equation: x + y = 32.

3. Determine the cost equation for the mixture. Since nuts sell for $3.50 per pound and raisins sell for $1.50 per pound, the cost equation is: 3.50x + 1.50y = 2.75 * 32.

4. Simplify the cost equation: 3.50x + 1.50y = 88.

5. Now, we have a system of equations: x + y = 32 and 3.50x + 1.50y = 88.

6. Solve the system of equations. You can use substitution, elimination, or any other method you prefer to solve the system. Let's solve it using substitution:

From the first equation, we can rewrite it as x = 32 - y.

Substitute this value into the second equation: 3.50(32 - y) + 1.50y = 88.

Simplify the equation: 112 - 3.50y + 1.50y = 88.

Combine like terms: -2y = -24.

Divide both sides by -2: y = 12.

7. Now that we have the value of y, substitute it back into the first equation to find x: x + 12 = 32.

Solve for x: x = 20.

8. Therefore, to get a 32-pound mixture selling for $2.75 per pound, you should use 20 pounds of nuts and 12 pounds of raisins.
