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.
Answer:
true
Step-by-step explanation:
An inequality that can be used to describe the possible values of x is; C. 0 < x < 14
<h3>How to calculate the angle in a triangle?</h3>
From the given image, let us first use sine rule to find the angles in the triangle with sides 12, 6 and 7 and angle 120°. Thus;
7/sin α = 12/sin 102
sin α = (7/12) * sin 102
sin α = 0.570586
α = sin⁻¹0.570586
α = 34.8°
We know that sum of angles in a triangle is 180°. Thus;
34.8° + 90° + (7x + 4) = 180°
124.8 + 7x + 4 = 180
7x = 180 - 128.4
x = 51.6/7
x = 7.37
Looking at the given options, x cannot be negative and that rules out the first option. x is greater than 8/7 and that rules out the second option but x is greater than 0 and less than 14 and so option C is correct.
