Bob and his best friend bill have the same birthday, but bob is 3 years older than bill. let the variable x represent bob’s age and y represent bill’s age. which equation models the relationship between bill’s age and bob’s age?
a. y = x/3
b. y = x + 3
c. x = y + 3
d. y = 3x
is the statement true or false? (ab)c = a(cb).
a. true
b. false

529 and 531

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
