Thuy planned for a square table to have a side length of 30 in, but found that it could be a little bigger at 39 in. She found the
change of scale below.
39 in. - 3 13
30 in 3 10
The changer scaleis 13 to 10
What is Thuy's error?
30 in
Thuy should have written the ratio as 3in.
30 in
Thuy should have written the ratio as 39 in-
Thuy should have divided both numbers by 6.
Thuy should have divided both numbers by 13.

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
