Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.

Answer:
10 (X+1)
Step-by-step explanation:
Length = 2x + 5
Width = 3x
Perimeter of rectangle= 2(L + W)
P= ![2\times (2x+5+3x)](https://tex.z-dn.net/?f=2%5Ctimes%20%282x%2B5%2B3x%29)
P= ![2\times (5x+ 5)](https://tex.z-dn.net/?f=2%5Ctimes%20%285x%2B%205%29)
Now, taking 5 as common
P= ![2\times 5 (x + 1)](https://tex.z-dn.net/?f=2%5Ctimes%205%20%28x%20%2B%201%29)
∴ Perimeter of rectangle= ![10\times (x+1)](https://tex.z-dn.net/?f=10%5Ctimes%20%28x%2B1%29)
