rick bought a book on mathematics for $51.75, a book on science for $74.52, a book on history $ 25.47 , and a book on general knowledge for $ 36.60 how much did he spend the books altogether

188.34

Step-by-step explanation:

74.52 + 25.47 + 36.60 + 51.75 = 188.34

Sorry I couldn't explain more, but I hope this helps!

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
