Answer:
y=5/16 - x/2
make y the subject of the formula and simplify afterwards
Answer:
<u>For the equation x = - 2/3</u>
Step-by-step explanation:
Solve the equation 2/3-4x+7/2=-9x+5/6
-4x + 9x = 5/6 - 2/3 - 7/2 (Putting the all the x values on the left)
5x = (5/6 - 4/6 -21/6)
5x = -20/6
x = - 20/6 /5 (Dividing by 5 at both sides)
x = -20/6 * 1/5
x = -4/6 = - 2/3 (Simplifying)
Proof of replacing x by -2/3
2/3 - 4 (-2/3) + 7/2 = -9 (-2/3) + 5/6
2/3 + 8/3 + 7/2 = 18/3 + 5/6
10/3 + 7/2 = 6 + 5/6
20 + 21 = 36 + 5 (Multiplying by 6 at both sides)
<u>41 = 41</u>
<u>It means the value of x is correct</u>
Answer:
The answers are :
1. 5%.
2. 467.50 DKK.
Step-by-step explanation:
Given:
Discount on Monday of a good at 10 percent.
Increase discount on Friday would be 15 percent.
1. Difference between the percentage = 
.
So, the percentage increase in discount is 
.
2. First, the actual price means the price without discount should be calculated.
So,let the actual price be 
:
According to question,
of
=
Multiplying both sides by 100
=
Dividing both sides by 90
=
.
And, now the price after the announcement of the 
discount
of
=
% of
=
=
=
.
So, the price after the announcement of the 
percent discount is DKK.
Therefore, the answers are :
1. 5%.
2. 467.50 DKK.
