Hello.

In 10 years, his age will be

\mathrm{z+10}

The sum of his current age and 10 equals his age in 10 years.

2 years ago his age was

\mathrm{z-2}

The difference of his current age and 2 equals his age 2 years ago.

7 years ago his age was

\mathrm{z-7}

The difference of his current age and 7 equals his age 7 years ago.

Therefore, his age after 10 years will be \mathrm{z+10}, his age 2 years ago was \mathrm{z-2}, and his age 7 years ago was \mathrm{z-7}

I hope it helps.

Have a nice day.

Question 29: In a club of 35 boys and 28 girls, 80% of the boys and 25% of the girls have been members for more than 2 years. If
klasskru [66]

Answer:

55%

Step-by-step explanation:

What we must do is get the total number of people, that is, boys and girls who have been a member for more than 2 years, that is:

children: 0.8 * 35 = 28

girls = 0.25 * 28 = 7

Now, passing knowing the%, would be dividing the sum of the above by the sum of the total club members:

(28 +7) / (35 + 28) = 0.55

Since it is a number below 1, it cannot be a mixed number.
