7s plus 8t plus 10s plus 12t can be simplified to 17s plus 20t.
ok i get this
there are 7 tenths in 275 or 2.75 10s
10S + 40 HNO3 → 10 H2SO4 + 40 NO2 + H2OS + 6HNO3 → H2SO4 + 6NO2 + 2H2OS + 4HNO3 -→ SO2 + 4NO2 + 2H2O
3s + 4t + 2s + 5s + 6tGroup all of the like 's' terms & 't' terms together:(3s+2s+5s) + (4t + 6t)10s + 10t or 10(s+t)
7/10 of a dollar + 2 dollars = 2 dollars and 70 cents or $2.70.
There are 8 10s in 85, with 5 left over.
Sadly, the phrase "10s to 76w longitude" is quite meaningless.-- As soon as you say "10s" or "10 south", that's the latitude.-- 10s/76w is the latitude and longitude of a point. The point isin central Peru, about 165 miles northeast of the center of Lima.

Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question. What do you want? To evaluate it (impossible), factorise it, something else?
