Answer:
Step-by-step explanation:
⅔(x-6) = ¾(x+16)
Multiply both sides by 12
8(x-6) = 9(x+16)
8x - 48 = 9x + 144
x = -192
Help you with what? where’s the problem?
4.50 per walk
At least 50
we can write an equation to solve for how many walks, w,
4.50w = 50
divide both sides by 4.50
w = 11.111...
That is, he will have to walk about 12 times to earn at least $50 when charging $4.50 for a walk with the dogs.
Hope this helps :)

Answer:
x^2 +4
Step-by-step explanation:
It is perhaps easiest to simply try the answers to see what works. x=1 corresponds to the first term, so the different answer choices will give that value as ...
3x² +4 = 3 +4 = 7
x² +4x = 1 + 4 = 5 . . . . possible solution
x² +4 = 1 +4 = 5 . . . . possible solution
x² +5 = 1 +5 = 6
Then for x=2, we want the result to be 8. The two choices we've identified so far give ...
x² +4x = 2² +4·2 = 12
x² +4 = 2² +4 = 8 . . . . . this is the solution
