Answer:
$128.37
Step-by-step explanation:
Find 33% of 389:
389(0.33) = 128.37
The amount of the discount is $128.37
Answer:
The percentage decrease of the shirt's price is 15%.
Step-by-step explanation:
1) divide 36.15 by 30.75
30.75/36.15=0.85
2) Multiply 0.85 by 100 to find the percentage between the original and sale costs of the shirt
0.85(100)= 85%
3) Find the difference between 85% and 100% to find the percentage difference
100%-85%= 15%.
Therefore, the answer is 15%.
Hope this helps!
Step-by-step explanation:
the perimeter of a rectangle is
2×length + 2×width =
2×(x + 10y) + 2×(7x² - x + 9y) =
2x + 20y + 14x² - 2x + 18y =
14x² + 38y
y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em>
</em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y = 
Answer:
x = 6, y = 5
Step-by-step explanation:
When x = 6 and y = 5,
3(6) - 5 = 13
18 - 5 = 13
13 = 13
L.H.S = R.H.S
