A local electronics store raised its prices on headphones by 20%. The headphones that Stan wants to buy now cost $36. How much did the headphones cost before the price increase?
Answers
Since there was 20% increase, the new price would be:
(100% + 20%) = 120%
120% x = 36
(120/100)x = 36
1.2x =36
x = 36/1.2
x = 30.
Price before the increase = $30.

Multiply both sides by K to get rid of the denominator
KL = P + 2G
Subtract P from both sides
KL - P = 2G
Divide each side by 2
KL - P / 2 = G
G = KL - P / 2
Hi Brand
L=P+(2G)/k
Multiply both sides by K
KL= KP+2G
Flip the equation
KP+2G=KL
add -KP to both sides
KP+2G-KP=KL-KP
2G=KL-KP
Divide both sides by 2
2G/2= (KL-KP)/2
G= 1/2 KL + -1/2 KP
I hope that's help !

The value of the expression 4 x 12, using multiplication distributive propoerty, is 48.
What is multiplication?
Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
An expression,
4 x 12.
To find the product:
We will apply the multiplicationoperation.
4 x 12
= 4 x (10 + 2)
Using the process of distributiveproperty,
= 4x 10 + 4 x 2
= 40 + 8
= 48.
Therefore, the value of the product is 48.

First, subtract 7 from both sides. / Your problem should look like:
Second, subtract 11 - 7. / Your problem should look like:
Third, divide both sides by -4. / Your problem should look like:
Fourth, change the fraction to a negative. / Your problem should look like:
Fifth, cancel 4 out. / Your problem should look like:
Answer: x = -1
-4x+7=11 (subtract 7 on both sides)
-4x=4 (divide -4 on both sides)
x=-1
