Profit = revenue - expenses
250 = 25x - (12x + 60)
250 = 25x - 12x - 60
250 = 13x - 60
250 + 60 = 13x
310 = 13x
310/13 = x
23.85 = x....so she would have to sell 24 purses
If a graph is proportional then the line will go through the origin at point (0, 0). If the equation is proportional then it will be in the form of y=kx with no other operations after. The constant of proportionality is another way to say the slope and in your specific equation the slope would be 1/5.
Answer:
Ratio of online sales to shop sales = 3 : 1
Step-by-step explanation:
Total necklace sold in a month = 240
Necklace sold via shop's website = 180
the rest were sold in a high street shop.
Necklace sold via high street shop = Total necklace sold in a month - Necklace sold via shop's website
= 240 - 180
= 60
Necklace sold via high street shop = 60
Ratio of online sales to shop sales
Necklace sold via shop's website : Necklace sold via high street shop = 180 : 60
= 180 / 60
= 3 / 1
= 3 : 1
Ratio of online sales to shop sales = 3 : 1

Step-by-step explanation:
Answer:
x = 36.87 degrees.
Step-by-step explanation:
4 cos x + 3 sin x = 5
Use the Auxiliary angle method:
R sin (α + x) = R sin α cos x + R cos α sin x
Comparing coefficients:
R sin α = 4 and R cos α = 3
R sin α / R cos α = 4/3
So tan α = 4/3
α = 53,13 degrees.
Now R^2(sin^2 α + cos^2 α ) = 3^2 + 4^2 = 25
R^2 = 25
R = 5.
R sin (x + 53.13) = 5
5 sin ( x + 53.13) = 5
sin (x + 53.13) = 1
x + 53.13 = 90
x = 36.87 degrees.
