Answer:
The correct form for each case is:
- a) 4 (5x + 6) = 20x + 24
- b) -5 (2x - 3) = -10x + 15
- c) 3 (9x + 2y) = 27x + 6y
Step-by-step explanation:
I'm gonna give you the reason for each case.
a) The original equation is:
Now, we're gonna solve the first part of the equation and comparate:
How you can see, the first part is different from the last number, for this reason, the mistake is the 6, then I change it by the 24.
b) The original equation is:
As the previous exercise, we're gonna solve the first part:
You must know that when you multiply two negative signs, the result is positive.
c) The original equation is:
But, this equation can be made in this form:
How you can see, the first part can't be operated or anything, the one form to operate this is removing the plus sign and operating like a multiply.
- 3 (9x + 2y) = 27x + 6y
- 27x + 6y = 27x + 6y
2 is congruent to 5. 180-130=50. Answer would be 50
You multiply 1.4x10= 14 and 7x10=70 then divide both by 14 and get 1/5 <span />

Answer:
3 pencils
Step-by-step explanation:
We are given Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
Number of pencils=72
Number of calculators=24
If Zayed creates the greatest number of identical packages
Then , we find GCF of 72 and 24
![72=2\times 2\times 2\times 3\times 3](https://tex.z-dn.net/?f=72%3D2%5Ctimes%202%5Ctimes%202%5Ctimes%203%5Ctimes%203)
![24=2\times 2\times 2\times 3](https://tex.z-dn.net/?f=24%3D2%5Ctimes%202%5Ctimes%202%5Ctimes%203)
GCF=![2\times 2\times 2\times 3](https://tex.z-dn.net/?f=2%5Ctimes%202%5Ctimes%202%5Ctimes%203)
Hence, Zayed creates 24 packages.
Number of pencils in each package=![\frac{72}{24}=3](https://tex.z-dn.net/?f=%5Cfrac%7B72%7D%7B24%7D%3D3)
Hence, 3 pencils and one calculator will be in each package .
