Subtract 17 from both sides:
<span>Sales
tax on a jacket with the price of 725 dollars.
the sales tax rate is 7%
=> Convert 7% into decimals
=> 7% / 100 = 0.07
Now, multiply the 0.07 in 725 dollars
=> 50.75
thus the total tax rate of the jacket price is 50.75
Now, let us calculate the total amount that you will be paying
=> 725 + 50.75
=> 775.75 = the total amount to be paid.</span>
Let's clear out the fraction(s):
Mult. all 3 terms by 3, obtaining 18 = 3x + 2. Simplifying, 16 = 3x.
Then x = 16/3 (answer).
Check: does (16/3) + (2/3) = 6? Yes, since 18/3 = 6.
Answer:
x = 14; y = 8
Step-by-step explanation:
A perpendicular intersection means an intersection between 2 lines, forming angles of 90°. Then:
7x - 8 = 90°
11y + 2 = 90°
7x - 8 = 90
7x = 90 + 8
7x = 98
x = 98/7
x = 14
11y + 2 = 90
11y = 90 - 2
11y = 88
y = 88/11
y = 8
I hope I've helped you.
