-2(x+3)<20 Show work and write solution set

Mathematics
1 answer:
Digiron [165]4 years ago
3 0

Answer:

x > - 13

Step-by-step explanation:

Given

- 2(x + 3) < 20 ← distribute parenthesis on left side

- 2x - 6 < 20 ( add 6 to both sides )

- 2x < 26

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x > - 13

solution set is { x | x > - 13 }

Dmitrij [34]

Answer:

C. 1 day

Step-by-step explanation:

Chris:

10 - 4d

Evan:

8 - 2d

How many days will it take before they both have the same number of bags remaining?

Equate both expressions and solve

10 - 4d = 8 - 2d

Collect like terms

10 - 8 = -2d + 4d

2 = 2d

Divide both sides by 2

d = 2/2

= 1

d = 1 day

It will take 1 day before they both have the same number of bags remaining

Is the selection below a​ permutation, a​ combination, or​ neither? Explain your reasoning. Upper A group of 5 senators is chose
Natalka [10]

Answer:

Combination, but keep in mind that if the committee had two open positions, say President and Secretary, it would be a permutation

Step-by-step explanation:

The first thing to keep in mind is the difference between combination and permutation.

The main difference is that in the combinations the order does not matter, whereas in the permutations the order does matter.

Combination example:

Choose 7 people for a project.

Example of permutation:

Choose 5 men for each specific role in a soccer team.

Therefore, "group of 5 senators is chosen to be part of a special committee" is a combination, but keep in mind that if the committee had two open positions, say President and Secretary, it would be a permutation.
