Question

collect the shells on the beach. i multiply the number of shell by 5. multiple by 7 divide by 2. I end with the number of 735.how many did i get collected.​

Answer 1

Answer:

let 'x' be the number of shells

((x×5) ×7) /2 = 735

(5x×7) /2 = 735

35x /2 = 735

35x = 735×2 = 1470

x = 1470/35 = 42

x=42

hope this helps
