Answer:
The width of the equation is 3 and the length is 9
Step-by-step explanation:
This problem was kind of simple for me to answer. The first thing I did was divide the 4 sides of the perimeter into sections which would bring me to find that it was 6 inches on each side then I divided that by 2 bringing me to the answer of 3. Then I decided to multiply 3 by 3 which brought me to the answer 9. I decided to try it around the perimeter which would be....
9+9+3+3=?
I added the 9's first which gave me 18 .Then added the 3's together which gave me 6. The final step I added 6 and 18 together and got 24.
Giving the fact that the length is 3 times greater than the width I came to the conclusion that....
3 is the width and 9 is the length.

Step-by-step explanation:
Domik weights 30 pounds more than his sister
Together they weigh 330 pounds
Let "x" represent the weight of Dominik's sister, then his weight can be expressed as "x+30"
And their total weight can be calculated as:

From this expression you can calculate the value of x:

x=150 pounds
x+30=150+30=180 pounds
Dominik weights 180pounds and his sister 150 pounds
