The correct answer for the question that is being presented above is this one: "D. 3 and 60." The means of the proportion is 15 and 12. <span>The </span>means-extremes<span> property of </span>proportions<span> allows you to cross multiply, taking the product of the </span>means and setting them equal to the product of the extremes<span>. </span>
Let the unknown number be 
.
Then the opposite of this unknown number will be 
.
It is given to us in the question that when this unknown number, is increased by 9, or in other words when 9 is added to this unknown number, , then this becomes 5 times it's opposite, which is .
Thus, from the given condition in the question, the equation we get is as:
We will solve this by isolating as:
Thus the required number is -1.5
Answer:
Area: ½ × base × height
Perimeter: sum of side lengths of the triangle
Number of vertices: 3
Number of edges: 3
Internal angle: 60° (for equilateral)
Sum of interior angles: 180°
Line of symmetry: 3
Step-by-step explanation:
Hey mate!
You stuck?
Xian and Kai would both need to receive stamps for 6 months to eventually have the same amount of stamps.
Xian: 12 stamps from club x 6 months + 56 stamps = 128
Kai: 8 stamps from club x 6 months + 80 stamps = 128
Hope this helps! :)
