Answer:
Lacy is 13 and Jack is 52
Step-by-step explanation:
In 3 years their ages will add up to 71 so you have to subtract 6 as there are two of them to get 65. Lacy's age is represented by x and since Jack is 4 times older his age is represented by 4x. So added together their age is 5x. So 5x=65. Then 65/5=13. So 13=x. So Lacy is 13 and Jack is 52 as 13x4 is 52.

1.) The area of a room 6 1/5 meters long and 5 3/4 meters wide is <u>A</u><u> </u><u>=</u><u> </u><u>l</u><u> </u><u>x</u><u> </u><u>w</u><u>;</u><u> </u><u>l</u><u> </u><u>=</u><u> </u><u>6</u><u> </u><u>1</u><u>/</u><u>5</u><u> </u> or <u>3</u><u>1</u><u>/</u><u>5</u><u>;</u><u> </u><u>w</u><u> </u><u>=</u><u> </u><u>5</u><u> </u><u>3</u><u>/</u><u>4</u><u> </u> or <u>2</u><u>3</u><u>/</u><u>4</u>
Here's the Solution:
- A = l x w; l = 6 1/5 or 31/5; w = 5 3/4 or 23/4
- A = 31/5 m x 23/4m
- A = 713/20 m^2
- A = 35 13/20 m^2
