You are at a football game. You decide to buy a hamburger for each of your 5 friends at the game. You also bought a soda for yourself for $4. You spent
a total of $21.50. How much do the hamburgers cost? WHICH EQUATION
FITS THIS SCENARIO?
4x + 5 = 21.50
21.50x + 5 = 4
5x - 4 = 21.50
5x + 4 = 21.50

5x-4=$21.50

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
