Answer:
I think it's x=-12 for the buttom one
Step-by-step explanation:
I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1
so take the 25 away from 1. to do that we need to do the opisite of +
2x + 25 = 1
1 - 25 = -24
rewrite
2x = -24
take the 2 away. oppisite of mulitplication is division. so divide 2 by -24
-24 divided by 2 = -12
Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D
Answer:
5%
Step-by-step explanation:
You want to find r when ...
I = Prt
is equal to P and t=20.
P = Pr·20 . . . . fill in the problem values
1/20 = r = 0.05 = 5% . . . . divide by 20P
The simple interest rate is 5%.
According to steam tables, steam produced from liquid water at 100 deg. C and standard atmospheric pressure (101.3 kPa) is 2257.0 kJ/kg.K.
Note : this value varies greatly with pressure and temperature.
