Answer:
m = - 1
Step-by-step explanation:
Given
m = - (4 + m) + 2 ← distribute and simplify right side
m = - 4 - m + 2
m = - 2 - m ( add m to both sides )
2m = - 2 ( divide both sides by 2 )
m = - 1
Answer:
4x+12
Step-by-step explanation:
(x+2)+(x+2)=2x+4
(x+4)+(x+4)=2x+8
(2x+4)+(2x+8)=4x+12
the mix number would be 1 and 1/15 and the improper fraction would be 16/15. 2 and 2/3 into a improper fraction and multiply it by 2/5 equals you answer.
We need to find the unit price of each box.
So, a box that weighs 30 Oz costs $4.50.
lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.
Unitary method is a process to find the value of a single unit.
Now,
30 Oz costs $4.50
therefore, 1 Oz should cost:
dollars
So, the unit price of box 1 is $0.15.
Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.
Now,
20 Oz box costs $3.60
therefore, 1 Oz should cost:
dollars
So, the unit price of box 2 is $0.18.
