50 hurryat a bargain store, tanya bought 5 items that each cost the same amount. tony bought 6 items that each cost the same amount, but each was $1.75 less than the items that tanya bought. both tanya and tony paid the same amount of money. what was the individual cost of each person's items? (a) write an equation. let x represent the cost of one of tanya's items. (b) solve the equation. show your work. (c) check your solution. show your work. (d) state the solution in complete sentences.

(a) 5x = 6(x-1.75) = 6x - 6×1.75 = 6x - 10.50

(b) 5x = 6x - 10.50

5x - 6x = 6x - 10.50 - 6x

-1(-1x) = -1(-10.50)

x = 10.50

(c) 5×10.50 =? 6×(10.50-1.75)

52.50 =? 6×(8.75)

52.50 = 52.50 ✔

(d) Tanya bought 5 items at $10.50 each.

Tony bought six items at $8.75 each.

They each spent $52.50

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
