12:7
12(2):7(2)
24:14
12:7 = 24:14
I hoped I helped(:
Here are two ways of doing it.
************************************************************
1) The current price is 100% of the price. The price went down by 6%, so since 100% - 6% = 94%, the new price is 94% of the original price.
94% * 175 = 0.94 * 175 = 164.50
The new price is 164.50
*******************************************************
2) The discount is 6% of 175, so first, we find the discount.
6% of 175 = 0.06 * 175 = 10.5
Now we subtract the amount of the discount from the original price.
175 - 10.50 = 164.50
The new price is 164.50
**********************************************************
As you can see, both methods give you the same answer, 164.50
<u>Solution</u><u>:</u>
- Now, square root and square gets cancel out in the LHS. And in the RHS, apply the identity: (a + b)² = a² + 2ab + b².
- Now, transpose 4x and 4 to LHS.
- Now, do the addition and subtraction.
<u>Answer</u><u>:</u>
<u>x </u><u>=</u><u> </u><u>±</u><u> </u><u>3</u>
Hope you could understand.
If you have any query, feel free to ask.
The solved inequality is t > 12.
Divide both sides by 9 to isolate the variable.
9t becomes t, and 108 becomes 12.
<u>We do not flip the sign because we are dividing by a </u><u>positive</u><u>.</u>
