It's A.

You've got 3 as a coefficient on both sides, so you can divide both sides by 3 to cancel them out. Then you've got:

x + 4 = x - 5

You know that this can't have a solution because there is no value x where if you add 4 to it and subtract 5 from it, you'll get the same thing.

So, the problem with the equation is that the x values have to be the same, but the constant numbers added/subtracted are different.

George is helping the manager of the local produce market expand her business by distributing flyers
spin [16.1K]

Answer:

20 + 0.05x ≥ 65

Step-by-step explanation:

20 is by itself since thats what he earns extra per day.

Since he earns 0.05 per flyer, that means we are going to need a variable since we don't know how many flyers he passes. Let x be equal to that.

Since he wants to make at LEAST 65 we are going to use the greater than or equal to symbol since he doesn't want to make less than that.

20 + 0.05x ≥ 65

Best of Luck!
