The discount is 40% that means the discount is 40% off from the original price. Or we could write the discount as below.
discount = 40% × original price
Find the original price
original price = sale price + discount
original price = 36 + 40% original price
100% original price = 36 + 40% original price
100% original price - 40% original price = 36
60% original price = 36
0.6 original price = 36
original price = 36/0.6
original price = 60
The original price of the headphone is $60
Step-by-step explanation:
Left hand side:
tan 203° + tan 22° + tan 203° · tan 22°
From angle sum identities, we know:
tan (α + β) = (tan α + tan β) / (1 − tan α · tan β)
Therefore:
tan (203° + 22°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan (225°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
1 = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan 203° + tan 22° = 1 − tan 203° · tan 22°
Substituting:
1 − tan 203° · tan 22° + tan 203° · tan 22°
1
4) 4m, 18, and g
5) 4n means 4xn
Answer:
or 
Step-by-step explanation:
we have
----> equation of the line into point-slope form
step 1
Convert to slope intercept form
The equation of the line into slope intercept form is equal to
so
----> equation of the line into slope intercept form
step 2
Convert to standard form
The equation of the line into standard form is equal to
so
we have
Adds 3x both sides
----> equation of the line in standard form
Its D because store a and store c are selling it for the lowest price.
