Answer:
Only Use addition or subtraction if the unknown variable is alone and not combined with a Number .
<u><em>EXPLANATION :</em></u>
Given step 1 to be =
4x = 28
Following the third law,
The correct solution would have been
Divide both sides of the equation by 4
x = 7
Step-by-step explanation:
"A General Rule for Solving Equations
- Simplify each side of the equation by removing parentheses and combining like terms.
- Use addition or subtraction to isolate the variable term on one side of the equation.( Note : This law can only be applies if the variable is alone e.g x and not combined e.g 4x)
- Use multiplication or division to solve for the variable" ( If variable is combined . Example : 4x
He would need at least a 96 on his last test to raise his score to a 90.
Answer:
ounces of clay are left in the bucket.
Step-by-step explanation:
We have been given that Luis and Glen share a 16-ounce bucket of clay. By the end of the week, Luis has used 5/8 of the bucket, and Glen has used 1/4 of the bucket of clay.
To solve our given problem, we need to subtract sum of clay used by Luis and Glen from total amount of clay.
![16-(\frac{5}{8}+\frac{1}{4})](https://tex.z-dn.net/?f=16-%28%5Cfrac%7B5%7D%7B8%7D%2B%5Cfrac%7B1%7D%7B4%7D%29)
Now, we will make a common denominator as:
![\frac{16\cdot 8}{8}-(\frac{5}{8}+\frac{1\cdot 2}{4\cdot 2})](https://tex.z-dn.net/?f=%5Cfrac%7B16%5Ccdot%208%7D%7B8%7D-%28%5Cfrac%7B5%7D%7B8%7D%2B%5Cfrac%7B1%5Ccdot%202%7D%7B4%5Ccdot%202%7D%29)
![\frac{128}{8}-(\frac{5}{8}+\frac{2}{8})](https://tex.z-dn.net/?f=%5Cfrac%7B128%7D%7B8%7D-%28%5Cfrac%7B5%7D%7B8%7D%2B%5Cfrac%7B2%7D%7B8%7D%29)
![\frac{128}{8}-(\frac{5+2}{8})](https://tex.z-dn.net/?f=%5Cfrac%7B128%7D%7B8%7D-%28%5Cfrac%7B5%2B2%7D%7B8%7D%29)
![\frac{128}{8}-\frac{7}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B128%7D%7B8%7D-%5Cfrac%7B7%7D%7B8%7D)
![\frac{128-7}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B128-7%7D%7B8%7D)
![\frac{121}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B121%7D%7B8%7D)
![15\frac{1}{8}](https://tex.z-dn.net/?f=15%5Cfrac%7B1%7D%7B8%7D)
Therefore,
ounces of clay are left in the bucket.
