I am a two-digit number. My ones digit is greater than my tens digit. Both my digits are even numbers. If you multiply me by 4, the estimated product is 280. What number am I? |

Answer» Let the digits be a, and b. Let the number result be c.10a+b=ca+b=13b=a+3If a+b=13, and b=a+3, then:a+a+3=132a+3 -3 =13 -32a=10, so a=5If b=a+3, and a=5, then:b=5+3, so b=810a+b=c, so 50+8=58So you are 58.Lets say the unit;s digit is X. The TEN’s digit would be X-3.Sum of digits = X + (X-3) = 13=> 2X = 16=> X = 8Thus, the unit’s digit is 8 and ten’s digit is 5. The number is 58.Step-by-step explanation:please MARK it brainliest |
