Answer:
I ≈ 251188643
Step-by-step explanation:
Given
R = logI [ note log I = 
I ]
Using the rule of logarithms
x = n ⇒ x = 
Substitute R = 8.4 into the equation, then
logI = 8.4
I = 
≈ 251188643
Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
3.c - 8 = 5
(3.c - product of 3 and a number)
(-8 : 8 less)
Answer:
215
Step-by-step explanation:
subtract 30 from 225
Answer:
125 sit ups
Step-by-step explanation:
well if you divide 60 by 12 you get five and if you multiply 25 and 5 you get 125
