Answer:
18
Step-by-step explanation:
x-5=(x+8)/2
x-5=x/2+4
add 5
x=x/2+9
subtract x/2
x/2=9
times 2
x=18
Working backwards, on Wednesday morning we have 60 / (1/2) = 120 pounds of ice.
2/3 melts on Tuesday so 120 pounds must be 1/3 of the ice.
120 / (1/3) = 360
Answer: D. 360
Your are being asked to find what value of a will result in the denominator being 0, since you can not divide by 0 then this will be your non permissible value. Simply take the denominator(after it has been factored down and reduced, if necessary, it's not in this question though) then set to 0 and solve for the variable.
![4a = 0](https://tex.z-dn.net/?f=4a%20%3D%200)
![a = 0 \div 4](https://tex.z-dn.net/?f=a%20%3D%200%20%5Cdiv%204)
![a = 0](https://tex.z-dn.net/?f=a%20%3D%200)
Therefore your non permissible value will be,
a ≠ 0
Based on the midsegment theorem of a triangle, the equation that relates AD and BE is: AD = ½(BE)
<em><u>Recall:</u></em>
- The midsegment theorem of a triangle states that length of midsegment = ½(the third side of the triangle).
Given the image attached below, where, TA=AB=BC and TD= DE = EF, considering ΔTBE:
- AD = midsegment of ΔTBE
- BE = third side of ΔTBE
Therefore, based on the midsegment theorem of a triangle, the equation that relates AD and BE is: AD = ½(BE)
