Answer:
-28
Step-by-step explanation:
multiply both 9 and 16 by 4 and then subtract the sum of 16 × 4 from 9 × 4.
Let
L----------> <span>the length of the yard
W--------> </span><span>the width l of the yard
we know that
the perimeter is equal to
</span>
![P=2*[W+L]](https://tex.z-dn.net/?f=P%3D2%2A%5BW%2BL%5D)
![72=2*[W+L] \\ 36=W+L](https://tex.z-dn.net/?f=72%3D2%2A%5BW%2BL%5D%20%5C%5C%2036%3DW%2BL)
--------> equation 1
![L=W+18](https://tex.z-dn.net/?f=L%3DW%2B18)
------> equation 2
<span>substitute equation 2 in equation 1
</span>
![36=W+18+W \\ 36=2W+18 \\ W=(36-18)/2](https://tex.z-dn.net/?f=36%3DW%2B18%2BW%20%5C%5C%2036%3D2W%2B18%20%5C%5C%20W%3D%2836-18%29%2F2%20)
![W=9 ft](https://tex.z-dn.net/?f=W%3D9%20ft)
![L=W+18 \\ L=9+18 \\ L=27 ft](https://tex.z-dn.net/?f=L%3DW%2B18%20%5C%5C%20L%3D9%2B18%20%5C%5C%20L%3D27%20ft)
<span>
we know that
Area of the rectangular yard is equal to
</span>
![A=L*W \\ A=27*9 \\ A=243 ft^{2}](https://tex.z-dn.net/?f=A%3DL%2AW%20%5C%5C%20A%3D27%2A9%20%5C%5C%20A%3D243%20%20ft%5E%7B2%7D%20)

Answer: 37 1/3
Step-by-step explanation:
14/1÷3/8=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
14/1 × 8/3=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
14×8/1×3 = 112/3
This fraction cannot be reduced.
The fraction
112/3
is the same as
112÷3
Convert to a mixed number using
long division so
112/3=37 1/3
Therefore:
14/1 ÷ 3/8=37 1/3
