3/2 = 1.5

Let the value of the 1945 coin = x.
Then, the value of the 1950 coin = 1.5x

Together, they are worth $40. This gives us the equation:

x + 1.5x = 40

2.5x = 40

x = 40/2.5

x = 16

1.5x = 1.5 * 16 = 24

Answer: The 1945 coin is worth $16. The 1950 coin is worth $24.

C and d are complementary. The measure of c is 4x and the measure of d is 26. What is the value of x
const2013 [10]

Answer:

The value of x is 16.    

Step-by-step explanation:

We are given the following in the question:

c and d are complementary angles.

Measure of c = 4x

Measure of d = 26

Since c and d are complementary, we can write from property of complementary:

c + d = 90

Putting values, we get,

4x + 26 =90\\4x = 90-26 = 64\\\\\Rightarrow x = \dfrac{64}{4} = 16

Thus, value of x is 16.
