Answer:
We can take 2 plates , 3 plates or 6 plates.
Step-by-step explanation:
1 dozen = 12 numbers
Total number of cookies = 42
Each plate has to get atleast 7 cookies ,all the plates should have the same number of cookies and also the number of plates must be greater than or equal to 2.
- If we take 2 plates , there can be 21 cookies in each.
- If we take 3 plates , there can be 14 cookies in each.
- If we take 6 plates , there can be 7 cookies in each.
These are the 3 possible cases.
Since there cannot be broken pieces, no other combination is possible.
24pr + 3(p + 2pr)
= 24pr + 3p + 6pr
= 24pr + 6pr + 3p
= 30pr + 3p
= 3p(10r + 1)
Explanation:
30pr + 3p
= 3p x 10r + 3p x 1
= 3p(10r) + 3p(1)
= 3p(10r + 1)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
3x-12
1)
Writing the expression in an equivalent form
3x-12
Factor out common term 3
3x-12 = 3(x-4)
Thus, 3(x-4) is equivalent to 3x-12.
2)
Writing the expression in an equivalent form
3x-12
Multiply the expression by 2/2
![3x-12\:=\frac{2}{2}\:\times \:\left[3x-12\right]](https://tex.z-dn.net/?f=3x-12%5C%3A%3D%5Cfrac%7B2%7D%7B2%7D%5C%3A%5Ctimes%20%5C%3A%5Cleft%5B3x-12%5Cright%5D)
Therefore, ![\frac{2}{2}\:\times \:\left[3x-12\right]](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D%5C%3A%5Ctimes%20%5C%3A%5Cleft%5B3x-12%5Cright%5D)
is equivalent to 3x-12.
Its used in all simlar instances
