Step-by-step explanation:
The first step is to find out what times 9 - 23 = 49 the first step would be to add 49 + 23 and that would get 72 so then you find that x would = 8 so the second step should be to put the problem together so 72 - 23 = 49. so basically x would equal 8.
Answer:

Step-by-step explanation:

Step 1: Divide the numbers

Step 2: Simplify

Step 3: Simplify

Therefore, the simplified answer is 
Well it depends. If your radical is wrapped around the entire expression, then your answer would be 3xy²z²√10xz, but if your radical is ONLY wrapped around 90, then your answer would be 3√10x³y⁴z⁵ [radical wrapped ONLY around 10]. So, with the way this is written, although it is simple to figure this out, it is difficult to find the answer you are looking for.
Although the question is a bit confusing, I believe the answer you are looking for is $2,763. If she can only go 2,000 past what she already has you just simply add it to the amount she does have.
2,000 + 763 = 2,763
Hope I helped!
Have a good day.
