Simplifying
5n + 3 = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n
Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n
Add '-5n' to each side of the equation.
3 + 5n + -5n = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 + 0 = 4 + 5n + -5n
3 = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 = 4 + 0
3 = 4
Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.
1/2, 6/12, 9,/18, and 15/30
Answer:
see below
Step-by-step explanation:
When the functions are inverses of each other, it will be true that ...
m(n(x)) = n(m(x)) = x
The expanded form of this equation is shown below.
L is length
w is width
p is perimeter
l = 3w-2
When a problem says "less than" (not "is less than"), you should put the minus sign BEFORE the number.
p = 60
The formula of perimeter is 2l + 2w
60 = 2l + 2w
Replace the l with the formula of l.
60 = 2(3w-2)+2w
Solve the problem:
Distribute
60 = 6w-4+2w
Combine lile terms
60 = 8w-4
64=8w
Divide
w=8
