3/4 divided by 2 would equal 3/8.
First, you want to establish your equations.
L=7W-2
P=60
This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.
<span>60=2(7W-2+W) </span>
<span>Now that we only have 1 variable, we can solve. </span>
First, distribute the 2.
60=14W-4+2W
Next, combine like terms.
60=16W-4
Then, add four to both sides.
64=16W
Lastly, divide both sides by 16
W=4
To find the length, we plug in our width.
7W-2
7(4)-2
28-2
<span>L=26</span>
Do you need help with all of them?
Answer:
No.
Step-by-step explanation:
No, because you can multiply or divide the length and breadth of rectangle A by the same number to get B
Answer:
To multiply mixed numbers:
Step-by-step explanation:
1. convert to improper fractions
2. top * top
3. bottom * bottom
4. convert back into a mixed number
