<h3><u>Question</u><u>:</u></h3>
Emily is 4 times as old as Tiffany. In ten years time, Emily will be twice as old as Tiffany. Find their ages.
<h3><u>Solution</u><u>:</u></h3>
- Let the age of Tiffany be x years.
- Then, the age of Emily = 4x years.
- After 10 years, the age of Tiffany will be (x+10) years.
- After 10 years, the age of Emily will be (4x+10) years.
- Therefore, by the problem
- So, Tiffany's present age = 5 years.
- Emily's present age = (4×5) years = 20 years.
<h3><u>Answer:</u></h3>
Emily's age is 20 years and Tiffany's age is 5 years.

Answer:
Acute i think
Step-by-step explanation:
Equation 1) y=2x
Equation 2) y=x + 1
Rearrange the equations so that x and y are on the same side.
1) -2x+y=0
2) -x+y=1
Subtract equations with each other.
Now you have: -x=-1
x=1
Plug in x.
y=2(1)
y=2
(1,2)

Method One:
Step One: Figure out how long the width is, witch is 19 feet.
Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide
Step Three: Add 38+33
The new perimeter will be 71 feet.
