Answer:
A is x - 4n / 3, B is 6k + 9n, C is 11k + 16n
Step-by-step explanation:
Pretty simple, you are adding the algebra grids, or substituting variables and making out an equation.
Solving for B: 4k + 6n + 2k + 3n = 6k + 9n
Solving for A: (2k + 3n) + x = 5k + 7n = x - 4n / 3
Solving for C: 6k + 9n + 5k + 7n = 11k + 16n
Answer:
none of these
Step-by-step explanation:
2x² + 7x + 4
Factor
We cannot factor this since 2*4 +1 = 9 and we want 7
and 2*2 +2 = 6 and we want 7
and 2*1 +4 = 6 and we want 7

Answer:
35 is the larger number.
26 is the smaller number.
Step-by-step explanation:
We don't know either number so let one of the numbers be x, the other one can be 9 less (so take away 9) x - 9
These two numbers add up to 61 ("sum" means adding)
x + x - 9 = 61
Combine the x's
2x - 9 = 61
Add 9 to both sides
2x = 70
Divide by two on both sides
x = 35
That's one of the numbers.
x - 9 = 35 - 9 = 26
So the numbers are 35 and 26.
35 is larger.
26 is smaller.
