is it 3 * 3/4 + 5 * 1/3? which way have you done?

**Math**

ok it can sometimes be easier to put in an equation of sorts. 6,279,000,000=2,556,000,000 * x then we multiply x by 100 to get % making x the %increase then just solve for x so 6,279,000,000/2,556,000,000=x x=2.4566 then multiply by 100 =245.66% now this does sound like a lot ...

**very easy algebra one**

it depends on whether (a t3) is (a*t3) or if it is (a+t3.)if (180s) is one term as well then. your expansions are either for (a*t3)(1) 180s*a*t3 or for (a+t3)(2) (180s*a)+(180s*t3)

**Chemistry**

Those are all the numbers in the problem. I worked further in the problem and found... (a) 15.9/20.29= 78.54% and for part (b) I found that 20.29g of MgCO3 makes .24mol CO2. So.... Pressure of CO2 = 12.54 atm. Does that seem right?
