Betty rearranged the movies on her shelving unit after a few days. She placed equal numbers of movies on the bottom 3 shelves, and 10 movies on each of the top two shelves. If x is the number of movies on each of the bottom 3 shelves, the expression for the total number of movies on the shelving unit is 3x + 20. How many movies are on the shelving unit if there are 11 movies on each of the bottom 3 shelves?

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.
