Answers:
- Sarah has $12.50
- Sam has $27.50
- Casey has $55
======================================================
Explanation:
x = amount of money Sarah has
x+15 = amount of money Sam has, since he has $15 more than her
2(x+15) = amount of money Casey has, since he has twice as much as Sam.
Let's add up those three expressions and set that sum equal to 95
Solve for x.
Sarah + Sam + Casey = 95
x+(x+15) + 2(x+15) = 95
x + x + 15 + 2x + 30 = 95
4x+45 = 95
4x = 95-45
4x = 50
x = 50/4
x = 12.50
This says that Sarah has $12.50
That must mean Sam has x+15 = 12.50+15 = 27.50 dollars
And Casey must have 2*27.50 = 55 dollars.
----------------
As a check,
Sarah+Sam+Casey = 12.50+27.50+55 = 95
So the answer is confirmed.
Answer:
You either need two sides and the angle between them or two angles and the side between them. Otherwise, you can construct a family of triangles that include the given pieces.
Step-by-step explanation:
"How do you find the missing sides of a triangle?"
I'm not a mathematician, but it seems to me that no one can find the missing sides (note the plural: "sides") of a triangle by having just one -- or none. You need at least two sides to get an answer...
