If two angles are complementary, the sum of their measures is 90 degrees. Call one of the angles x. This means that its complement is 90 - x degrees. But the difference in their measures is 12 degrees.
To find out which cake is better for the price, we need to multiply the cake amounts by how many cakes of that kind we need. You need 5 20cm cakes, so we multiply 5 by the price of the 20cm cake (13.50) to get $67.50. You need 3 25cm cakes, so 3 x 18.75 = 56.25.
20cm cake: $67.50
25cm cake: $56.25
Answer: The 25cm cake is cheaper for more people.

Answer:
x=5
Step-by-step explanation:
Formulate and substitute:d=4v
Rearrange unknown terms to the left side of the equation: 4x=27-7
Calculate the sum or difference: 4x=20
Divide both sides of the equation by the coefficient of variable: x=20÷4
Calculate the product or quotient: x=5
So the Answer is: x=5
