(5x3 + 4x2) – (6x2 – 2x – 9)

Answers

Answer:

The difference of the polynomials (5x3 + 4x2) – (6x2 – 2x – 9) is 5x3 – 2x2 + 2x + 9.

Step-by-step explanation:

Answer:

5x3−2x2+2x+9

Step-by-step explanation:

Distribute the Negative Sign:

=5x3+4x2+−1(6x2−2x−9)

=5x3+4x2+−1(6x2)+−1(−2x)+(−1)(−9)

=5x3+4x2+−6x2+2x+9

Combine Like Terms:

=5x3+4x2+−6x2+2x+9

=(5x3)+(4x2+−6x2)+(2x)+(9)

=5x3+−2x2+2x+9

27x + 15y = ? (9x + ? y)
Please help! I don't understand!

Answers

Answer:

3;5

Step-by-step explanation:

One side of the equation is 27x + 15y, the number of the first blank times 9x needs to be 27x, so it has to be 3. And 3 times {blank} y needs to be 15y, so the second blank has to be 5.

Hope this helps! :)

Answer:

27x + 15y = 3(9x + 5y)

Step-by-step explanation:

27x + 15y = ?(9x + ?y)

3 times 9 = 27

so the first ? would be 3

27x + 15y = 3(9x + ?y)

15/3 = 5

so the 2nd ? would be 5

27x + 15y = 3(9x + 5y)

Simplify to check your work.

27x + 15y = 3(9x + 5y)

27x + 15y = 3(9x) + 3(5y)

27x + 15y = 27x + 15y

The total cost of the 3 shirts including shipping is $71.83. They want to know how much each shirt costs without shipping so you are going to do $71.83 subtract $7.99. This gives you $63.84 for the 3 shirts without shipping. Now you are going to take $63.84 and divide by 3. This comes out to be $21.28 For each shirt.
I was just solving that equation out for you just in case. What you need to put in the box is this:

3s + 7.99 = 71.83

7/8m − 1/2= 3/16m + 5

Answers

Answer:

One Solution    m = 8

Step-by-step explanation:

7/8 m - 1/2 = 3/16 m + 5            Add 1/2 to both sides

7/8 m = 3/16 m + 5 + 1/2

7/8 m = 3/16 m + 5 1/2             Subtract 3/16 m from both sides

7/8 m - 3/16m = 5 1/5              Change 7/8 to 14 / 16

14/16 m - 3/16 m = 5 1/2           Subtract on the left. Change 5 1/2 to 5.5

11/16m = 5.5                                 Multiply both sides by 16

11m = 5.5 * 16

11m = 88

11m/11 = 88/11

m = 8

Mrs. Jones was very proud of her apple tree. One autumn, after harvesting her apples, she called her three sons together. “Here are 150 apples,” she said. “I want you to take them to the market tomorrow and sell them for me.” She gave Paul 15 apples, Nick 50, and Ben 85. “Your job,” added Mrs. Jones, “is to sell the apples in such a way that each of you brings home the same amount of money.” How do they do it?

Good Luck!! First Right Answer May Get Brianliest!!! : )

Answers

I think that the first person who came along to buy apples would have to buy 12 dozen apples at $1 per dozen. Paul’s sells one dozen, Nick sells 4 dozen, and Ben sells seven dozen. After that, Paul has 3 apples, Nick has 2, and Ben has 1. If they all sent their remaining apples at a price of $3, Paul would earn 9 more dollars, Nick would earn 6, and Ben would earn three. That puts them each with a profit of $10.
