Answer:
- Martin is 40 and Ada is 14
Step-by-step explanation:
- Martin's age = m
- Ada's age = a
<u>Martin is two years younger than three times his daughter Ada’s age:</u>
<u>The sum of their ages is 54:</u>
<u>Solving this equation for m:</u>
<u>Eliminate m:</u>
<u>Solve for a:</u>
- 3a + a = 54 + 2
- 4a = 56
- a = 56/4
- a = 14
<u>Find m:</u>
Martin is 40 and Ada is 14

If a number is divisible by 5, 6, and 7,
<span>it's divisible by 5 x 6 x 7 = 210, the least </span>
<span>common multiple of the numbers. So her number </span>
<span>is a multiple of 210. The only 4-digit multiple </span>
<span>is 210 that starts 210 _ is 2100, so that's her number.</span>
