Answer:
<em>-</em><em>1</em>
Step-by-step explanation:
<em>x</em><em> </em><em>is</em><em> </em><em>an</em><em> </em><em>unknown</em><em> </em><em>and</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>known</em><em> </em><em>as</em><em> </em><em><u>1</u></em><em><u> </u></em><em>or</em><em> </em><em><u>-</u></em><em><u>1</u></em><em><u> </u></em><em>based</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>circumstance</em><em>.</em><em> </em>
<em>Therefore</em><em>,</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>case</em><em>,</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>known</em><em> </em><em>as</em><em> </em><em><u>-</u></em><em><u>1</u></em>
So basically it's just a simple division equation (kind of):
600/3000
We can simplify this so the denominator is 100
20/100

The longest side in the figure measures 14 cm.
the side that is parallel to this side measures 9 cm.
if you are confused on how to look at this problem, look at it this way...
if we take away the side that measures 6 cm, we also need to take away 6 cm from the 10 cm side. if we do this, we end up with a 14 cm side and a 9 cm side with a missing (x) cm which we would add to the 9 cm side. look at it this way, if we put the 9 cm side and the (?) side on top of each other, it looks equal to the 14 cm side.
to solve for the length (in cm) of the missing side, I took 14 cm and subtracted 9 cm from it. when I did this, I got an answer of 5 cm. in conclusion, the missing side (?) is 5 cm.
the answers to the other two problems in your picture are:
5 cm
25 cm^2
125 cm^3

Answer:
13%
Step-by-step explanation:
the cost price of 1/3 of the sugar = 1/3 x 4500 = 1500
gain=
x 100
let x = unknown selling price
(x - 1500) / 1500 = 0.1
to solve for x, multiply both sides of the equation by 1500
x - 1500 = 150
x = 1650
the selling price of the 1/3 of sugar that yielded a 10% gain is 1650
to determine the gain percent of the remaining sugar, the selling price of the remaining sugar has to be determined . Let the selling price be represented by a
Based o the information in the question and the previous solution, the following equation can be derived
{(a + 1650) - 4500} / 4500 = 0.12
Solve for a
Multiply both sides of the equation by 4500
a + 1650 - 4500 = 540
a = 3390 = selling price of 2/3 of the sugar
Percent gain that the 2/3 of the sugar should be sold can be determined by taking the following steps
first find cost price of the 2/3 of sugar = 2/3 x 4500 = 3000
gain = (3390 - 3000) /3000 = 0.13 = 13%
