2. which expression is equivalent to the expression shown below? 20 + 8y - 9y - 21 select each correct answer. 2(10 + 4y - 7y - 19) 2(10 + 4y) - 3(3y - 7) 4(5 + 2y - 5y - 17) 4(5 + 2y) - 3(3y + 7) -(y + 1) -(1 - y) y - 1

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
