Answer:

Step-by-step explanation:
As far as I am able to observe from the statement of your question, the expression is:
![\left[[\left(3^3-7\right)\cdot \frac{5}{10}\right]+\left(\left(1+3+6+9\right)-1\right)](https://tex.z-dn.net/?f=%5Cleft%5B%5B%5Cleft%283%5E3-7%5Cright%29%5Ccdot%20%5Cfrac%7B5%7D%7B10%7D%5Cright%5D%2B%5Cleft%28%5Cleft%281%2B3%2B6%2B9%5Cright%29-1%5Cright%29)
So, lets solve this expression, which anyways would clear your concept
Considering the expression
![\left[[\left(3^3-7\right)\cdot \frac{5}{10}\right]+\left(\left(1+3+6+9\right)-1\right)](https://tex.z-dn.net/?f=%5Cleft%5B%5B%5Cleft%283%5E3-7%5Cright%29%5Ccdot%20%5Cfrac%7B5%7D%7B10%7D%5Cright%5D%2B%5Cleft%28%5Cleft%281%2B3%2B6%2B9%5Cright%29-1%5Cright%29)


Lets first solve

Answer:
Step-by-step explanation:
Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.
A = 49(B)
A+B=1.450
Substitute:
49B+B=1.450
50B = 1.450
B = 0.029
A = 49(B)
A = 49*(0.029)
A = 1.421
Prim numbers between 30 and 60 are
31, 37, 41, 43, 47, 53, and 59
First, you have to add 16 to both sides because it's the opposite of subtracting.
h-16<24
+16 +16
-16+16 will cancel each other out.
24+16=40
So, h<40
Or in other words, h is smaller than 40.
Hope it helps ^_^
