Which is the best interpretation of the solution set for the compound inequality?
3(2x + 1) > 21 or 4x + 3 < 3x + 7

(-∞, ∞)

Step-by-step explanation:

Let's solve each inequality separately.

The solution is x > 3 or x < 4

Since x could be less than 4 or greater than 3, x could be any number.

The best interpretation for the solution set is (-∞, ∞).

answer: the common difference is -0.10

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
