Answer:
7.25%
Step-by-step explanation:
The item she wants is priced at $20.
The total cost of the souvenir with tax is $21.45.
find:
What tax rate does Lacy pay for the souvenir?
$21.45 = tax ($20) + $20
tax = <u>( $21.45 - $20 )</u>
$20
tax = 0.725 x 100 = 7.25%
therefore, the tax of the souvenir is 7.25%
Its B or D!
I hope this helps!

Answer:
one solution: x = 5/7
Step-by-step explanation:
3 (x - 2) + 7x = 0.5 (6x - 2)
3x - 6 + 7x = 3x - 1
10x - 6 = 3x - 1
-3x -3x
7x - 6 = - 1
+ 6 + 6
7x = 5
/7 /7
x = 5/7
Answer:
Length = 8 m
Width = 30 m
Step-by-step explanation:
Let length = x.
Then width = 3(x + 2).
P = 2(L + W)
76 = 2[x + 3(x + 2)]
76 = 2[x + 3x + 6]
76 = 2[4x + 6]
8x + 12 = 76
8x = 64
x = 8
3(x + 2) = 3(10) = 30
Answer:
Length = 8 m
Width = 30 m
Consider
2x – y = 7
y = 2x + 3
Subst. 2x+3 for y in the first equation: 2x - (2x + 3) = 7
This boils down to 0 + 3 = 7, which simply is not true and can never be true.
Thus, this system of equations has no solution.
