Answer:
63/40, also known as 1 23/40.
Step-by-step explanation:
Uses = Subtract.
1. Find the LCD (Least Common Denominator) of 11/5 and 5/8. Can also be LCM (Least Common Multiple) of 5 and 8.
LCD = 40.
2. Make the denominators the same as the LCD.
![\frac{11*8}{5*8} - \frac{5*5}{8*5}](https://tex.z-dn.net/?f=%5Cfrac%7B11%2A8%7D%7B5%2A8%7D%20-%20%5Cfrac%7B5%2A5%7D%7B8%2A5%7D)
3. Simplify.
![\frac{88}{40} - \frac{25}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B88%7D%7B40%7D%20-%20%5Cfrac%7B25%7D%7B40%7D)
4. Simplify.
![\frac{63}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B63%7D%7B40%7D)
Mixed Number = ![1\frac{23}{40}](https://tex.z-dn.net/?f=1%5Cfrac%7B23%7D%7B40%7D)

Explanation
Step 1
Let
x represents the smallest number:
![x](https://tex.z-dn.net/?f=x)
as those are three consectutive intergers, the next interger is:
![x+1](https://tex.z-dn.net/?f=x%2B1)
this is the middle number:
middle number=x+1
the next consectutive number is
![\begin{gathered} x+1+1 \\ x+2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%2B1%2B1%20%5C%5C%20x%2B2%20%5Cend%7Bgathered%7D)
so, the third number is x+2
Hence,
Step 2
the sum of the smallest number and twice the middle
number is equal to 20 more than the third number?
replacing:
twice the middle=2(x+1)
![\begin{gathered} (x)+2(x+1)=20+(x+2) \\ (x)+2(x+1)=(x+2)+20 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28x%29%2B2%28x%2B1%29%3D20%2B%28x%2B2%29%20%5C%5C%20%28x%29%2B2%28x%2B1%29%3D%28x%2B2%29%2B20%20%5Cend%7Bgathered%7D)
so, the answer is
D
A because a function can NOT start with a 0 hope it helps:)
Answer:
Width = 4.5
Length = 7.5
Step-by-step explanation:
The perimeter is two times the length plus two times the width.
So 2(x+3) + 2x = 24 is the equation to solve.
2x+6+2x = 24
4x = 24-6
4x = 18
x = 9/2= 4.5
So the width = 4.5
Length = 4.5+3 = 7.5
First u divide by 2 then after that u divide by two agian and that should be your answer
