Answer:
The smaller number is -9.
Step-by-step explanation:
Let <em>x</em> and <em>y</em> be the two unknown numbers.
Their sum is -5. Hence:
Their difference is 13. Hence:
This yields a system of equations. We can solve this using elimination. Adding the two equations together:
Simplify:
Divide both sides by two. Thus:
Using either equation (I'll use the first):
So, our two numbers are 4 and -9.
The smaller number is -9.
Answer: 2 7/16 yards<span>
To find how much ribbon does she have left over you need to subtract the total ribbon with the ribbon used. Since the denominator of the two number is different, you need to find the least common multiple. LCM of 16 and 2 is 16, so the calculation would be:
</span><span>8 1/16 - 5 1/2=
3 1/16 - (1*8)/(2*8) =
</span>3 1/16 - 8/16=
2 7/16 yards
That’s the equation for the radius of a circle, it would equal r2
