Answer:
When combining like terms the given expression turned to the simplest form of expression 3(x+z)+5
That is 4x+7z-x+5-(4z)=3(x+z)+5
Step-by-step explanation:
Given expression is 4x+7z-x+5-(4z)
To combining the given expression to solve it as below :
4x+7z-x+5-(4z)
=4x+7z-x+5-4z
=4x-x+7z-4z+5 ( combining the like terms of x and z )
=3x+3z+5 ( here adding the like terms )
=3(x+z)+5 ( taking the common factor )
Therefore 4x+7z-x+5-(4z)=3(x+z)+5
When combining like terms the given expression turned to the simplest form of expression 3(x+z)+5
That is 4x+7z-x+5-(4z)=3(x+z)+5
Answer:
Original size of population containing fruit files = 10 files
Rate at which population of fruit file is increasing = 22.5%
New population of fruit files having initial population of 10 files and increase rate of 22.5% is given by =
10 + 22.5 × 
= 10 + 22.5 × 
= 10+ 2.25
= 12.25 files
Answer:
4 hours and 7 hours
Step-by-step explanation:
Marcus = x hours
Donnell = x + 3 hours
Total = 11 hours
- x + x + 3 = 11
- 2x + 3 = 11
- 2x = 8
- x = 4
So Marcus practiced 4 hours and Donnell practiced 7 hours
Answer:
6 =v
Step-by-step explanation:
-5(v - 1) = -6- (1 + 3v)
Distribute
-5v +5 = -6 -1 -3v
Combine like terms
-5v +5 = -7 -3v
Add 5v to each side
-5v+5v +5 = -7 -3v+5v
5 = -7+2v
Add 7 to each side
5+7 = -7+7 +2v
12 = 2v
Divide each side by 2
12/2 = 2v/2
6 =v
