In order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.
Step-by-step explanation:
Let hours of exercising horses be x --> $5 per hour = 5x
Let hours of cleaning stalls be y --> $10 per hour = 10y
Total earning = 
Total hours = 12
<u>Equation 1:</u>
5x + 10y = 
<u>Equation 2:</u>
x + y 
<em>1. Multiply equation 2 by -5</em>
x + y
(*-5)
5x + 10y = 
-5x - 5y
5x + 10y = 
<em>2. Solve</em>
-5x + 5x -5y + 10y = -60 + 90
5y = 30
y = 6
x + y = 12
x + 6 = 12
x = 6
Therefore, in order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.

The answer to this question would be 152,000
In this question, you are given multiple number names and asked to add it. To answer this question, it will be easier to split the sentences into multiple parts like this:
<span>1. "14 ten thousands" mean 14 * 10,000 =140,000
</span><span>2. "12 thousands" mean 12 * 1,000= 12,000
Then, if you add them up it will be: 140,000+ 12,000= 152,000</span>
