to prove that 6720. Sin 40. Sin 60. 80 equals 3 you'd have to divide 16 by 20 multiply subtract both sides by 3 which is 24x + 6x + 8x + -14 equals 40 40 + 20 equals 16 - -40 equals 80 which equals to 3

10 x 8 = 8 x [] unknown factor
Akimi4 [234]

Hey there!

10 * 8 = 8 * e

10 * 8 = 80

80 = 8 * e

8 * e = 80

8e = 80

DIVIDE 8 to BOTH SIDES

8e/8 = 80/8

CANCEL out: 8/8 because that gives you 1

KEEP: 80/8 because that gives the value of x

x = 80/8

80/8 = x

10 = x

x = 10

Therefore your answer is: 10

Because, 10 * 8 = 8 * 10

Good luck on your assignment and enjoy your day!
