100 points & will give brainliest! write the set using interval notation
{x| 3 < x < 13 and x 4

Step-by-step explanation:

We are given the set:

And we want to express this in interval notation.

In words, this reads: all values of x between 3 and 13 and x does not equal 4.

Hence:

We use parentheses as we do not include the values of 3 and 13 inside our interval. Likewise, since x cannot equal 4, we skip four, but use the union symbol to connect the two intervals.

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
