Y=250+2x is the amount she spends
y=12x is the amount she makes
If the amount she spent = the amount she makes then she break even
250+2x=12x
250=12x-2x
250=10x
So x = 250/10=25 necklaces she needs to sell to break even
Answer is 25 necklaces
Lance is not correct. Although his number does have more decimal places, his number is not greater. Angel has the greatest number in the most valued place, which is the tenths place in this case. We can understand this by knowing that 5>4. So, Angel has more water, and Lance is incorrect.
Answer:
The height of the triangle is: 
Step-by-step explanation:
Here, the area the triangle is given as: 
Also, base of the triangle = 
Let us assume the height of the triangle = H units
Now, AREA of TRIANGLE = 

Solving by LONG DIVISION, we get:

Hence, the height of the triangle is: 
3(x-4)=x-6
3x-12=x-6
3x-x = -6+12
2x=6
X= 3
It would be 6 because 3x2=6
