Answer:
43 and 5
Step-by-step explanation:
Let's let the two unknown numbers be a and b.
Their sum is 48, therefore:
![a+b=48](https://tex.z-dn.net/?f=a%2Bb%3D48)
And their difference is 38. In other words:
![a-b=38](https://tex.z-dn.net/?f=a-b%3D38)
We now have a system of equations. To solve, we can use substitution. First, add b to both sides in the second equation:
![a=38+b](https://tex.z-dn.net/?f=a%3D38%2Bb)
Substitute this into the first equation:
![(38+b)+b=48](https://tex.z-dn.net/?f=%2838%2Bb%29%2Bb%3D48)
Combine like terms:
![2b+38=48](https://tex.z-dn.net/?f=2b%2B38%3D48)
Subtract 38 from both sides:
![2b=10](https://tex.z-dn.net/?f=2b%3D10)
Divide both sides by 2:
![b=5](https://tex.z-dn.net/?f=b%3D5)
So, one of the numbers is 5.
The sum of them is 48. Therefore, the other number is 48-5 or 43.
So, our two numbers are 43 and 5.
And we're done!

Answer:
![y = 200 + x](https://tex.z-dn.net/?f=y%20%3D%20200%20%2B%20x)
Step-by-step explanation:
Given
![Prediction = x](https://tex.z-dn.net/?f=Prediction%20%3D%20x)
![Sales = \$200\ more](https://tex.z-dn.net/?f=Sales%20%3D%20%5C%24200%5C%20more)
Required
Determine the actual sales
Represent the actual sales with u
![y = Sales + Prediction](https://tex.z-dn.net/?f=y%20%3D%20Sales%20%2B%20Prediction)
![y = 200 + x](https://tex.z-dn.net/?f=y%20%3D%20200%20%2B%20x)
<em>Hence, the total sales can be expressed using y = 200 + x</em>
Answer:
![E=5000N/C](https://tex.z-dn.net/?f=E%3D5000N%2FC)
Step-by-step explanation:
From the question we are told that
Charge ![q= 60 \mu C](https://tex.z-dn.net/?f=q%3D%2060%20%5Cmu%20C)
Force ![F_=0.30N](https://tex.z-dn.net/?f=F_%3D0.30N)
Generally the equation for electric field strength is mathematically given as
![E=F/q](https://tex.z-dn.net/?f=E%3DF%2Fq)
![E=\frac{0.30}{60*10^-^6}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B0.30%7D%7B60%2A10%5E-%5E6%7D)
Therefore
![E=5000N/C](https://tex.z-dn.net/?f=E%3D5000N%2FC)
I believe x = 32 because it is an equalateral triangle meaning each angle is 60 degrees so the equasion is 2x-4=60.
