Your given question is unclear.
20.7 degrees C
Step-by-step explanation:
Here's the easiest way to solve. Grab a calculator, or a piece of paper. (its simple math) SOOOO, The start is 19.4. Then, it rises 3.8. So add that to 19.4. That gives you 23.2, BuT, it falls again, back down 2.5 degrees. so take 23.2, and subtract 2.5 from it. That should give you 20.7 degrees.
Answer:
x=13
Step-by-step explanation:
9^2 * 27^3 = 3^x
We need to get each term with a base of 3
9^2 = (3^2) ^2
We know that a^b^c = a^(b*c)
(3^2) ^2 = 3^(2+2) = 3^4
27^3 = (3^3) ^3 = 3^(3*3) = 3^9
Replacing these in the original equation
3^4 * 3^9 = 3^x
We know that a^b *a^c = a^(b+c)
3^4 * 3^9 =3^(4+9) = 3^13 = 3^x
The bases are the same, so the exponents must be the same
x=13
7539 + 3200 = 10739
the answer is 10,739
