Rashid and Megan need 40 felt patches.
Step-by-step explanation:
Draw a table with number of costumes in the first row and the number of felt patches in the second row.
Note that for 1 costume, 5 felt patches are needed.
For 2 costumes, 10 felt patches are needed
For 3 costumes, 15 felt patches are needed and so o.
So, the pattern in the table is whenever there is 1 increase in the costumes, there are 5 numbers increase in felt patches.
From the table, we can easily identify that the 8 costumes need 40 felt patches.
Hence, Rashid and Megan need 40 felt patche
Answer:
![\dfrac{7}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B10%7D)
Step-by-step explanation:
We need to find a rational number between 3/5 and 4/5.
We can find a rational number between two fractions as :
![\dfrac{a+b}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%2Bb%7D%7B2%7D)
We have, a = 3/5 and b = 4/5
So,
![\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B3%7D%7B5%7D%2B%5Cdfrac%7B4%7D%7B5%7D%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%5Cdfrac%7B7%7D%7B5%7D%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%7D%7B10%7D)
So, a rational number between 3/5 and 4/5 is equal to 7/10.

System of Linear Equations entered :
[1] y-x=3
[2] 2x+y=9
Equations Simplified or Rearranged :
[1] y - x = 3
[2] y + 2x = 9
Graphic Representation of the Equations :
x + y = 3 2x + y = 9
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -2x + 9
// Plug this in for variable y in equation [1]
[1] (-2x+9) - x = 3
[1] - 3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
y = -2x+9
x = 2
Solution :
{y,x} = {5,2}
