Write a system of equations (3 points) for the problem below and then solve it The candy shack has 20 lb. Of mixed white and dar
icang [17]

Answer: the mixture contained 15 pounds of white chocolate and 5 pounds of dark chocolate.

Step-by-step explanation:

Let x represent the number of pounds of white chocolate in the candy shack mixture.

Let y represent the number of pounds of dark chocolate in the candy shack mixture.

The candy shack has 20 lb of mixed white and dark chocolate. This means that

x + y = 20

The 20lb mixture is worth $7.50 per pound. This means that the total cost of the mixture is

20 × 7.50 = $150

White chocolate alone sells for $8.00 per pound and dark chocolate sells for 6.00 per pound. This means that

8x + 6y = 150 - - - - - - - - - - - - - -1

Substituting x = 20 - y into equation 1, it becomes

8(20 - y) + 6y = 150

160 - 8y + 6y = 150

- 8y + 6y = 150 - 160

- 2y = - 10

y = - 10/ - 2

y = 5

x = 20 - y = 20 - 5

x = 15

Pls help ill give brainliest
Ymorist [56]

Answer:

\boxed {\boxed {\sf (5g^2+2)(2g-5)}}

Step-by-step explanation:

We are given the expression:

10g^3-25g^2+4g-10

There are no common factors between the four numbers, however the first two have a common factor and the last two do too. Therefore, we can factor by grouping.

Group the first two terms and the last two.

(10g^3-25g^2)+(4g-10)

Find the greatest common factor (GCF) of the first group. It is 5g². Factor it out of the first group. You can do this by dividing both terms by the GCF.

  • 10g³/5g²= 2g
  • -25g²/5g² = -5

5g^2 (2g-5) + (4g-10)

Repeat with the second group. The GCF is 2.

  • 4g/2 = 2g
  • -10/2= -5

5g^2 (2g-5) + 2(2g-5)

There is another GCF: 2g-5. We can factor this out of both terms.

  • 5g²(2g-5)/2g-5= 5g²
  • 2(2g-5)/ 2g-5=2

(5g^2+2)(2g-5)

This cannot be factored further, so it is the answer.

Which expressions are equivalent to -6n+(-12)+4n
GaryK [48]

Answer:

-2n - 12

Step-by-step explanation:

Combine like terms. Note that each term has one variable (n). Also note  that one negative sign and one positive sign results in a negative sign.

-6n + (-12) + 4n = -6n  + 4n - 12 = -2n - 12

-2n - 12 is your answer
