So these are our two equations:
Before we can use elimination, subtract y on both sides of the first equation:
Now we are able to use elimination. To eliminate the y variable, add the two equations together to get . From here we can solve for x.
For this, just divide both sides by 3 and your first answer will be
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, x = 3 and y = 6.</u>
The correct answer would be 4 x 10^4 sq ft.
It’s 0.441 just really got to read it right that’s all
Total room in the 2 suitcases is 33 ft³
Step-by-step explanation:
- Step 1: To find the total room in the suitcases, find volume of the suitcases, given by V = length × width × height
⇒ Volume of 1st suitcase = 3 × 2 × 4 = 24 ft³
⇒ Volume of 2nd suitcase = 3 × 1 × 3 = 9 ft³
∴ Total room in Sandra's suitcases = 24 + 9 = 33 ft³
Question 1:
Perimeter = 18ft
area = 15ft²
Question 2:
Perimeter = 11m
Area = 7.5m²
