90 / (10 + 9 - 4)

90 / 15

=6

Your answer is 6!

90 / [10 + (3^2 - 4)]

1st solve: (3^2 - 4)

= 5

= 90 / [10 + (5)]

2nd solve:  [10 + 5]

= 15

= 90 / [15]

3rd solve: 90 / 15

= 6

Final

6

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
