Answer:
C,
Step-by-step explanation:
:)
-8n+7=31
-8n+7-7=31-7
-8n=31-7
-8n=24
-8n÷(-8)=24÷(-8)
n=24÷(-8)
n=-24÷8
n=-3
Without using a calculator I would say the root is between 10 and 11
How I found the answer:
I know 10 * 10 = 100
I know 11 * 11 = 121
So the root of 100 = 10 and the root of 121 = 11 so that means the root of 108 is somewhere between 10 and 11, which the root of 108 = 10.3923
w = ¼
so 12w= 3
because we set it up like 5w-1= w then subtract the w so it’s on the same side as the other w. then we add the one and divide the one by 4 to get the w by itself. then you plug the ¼ into the equation 12(w) to equal 3!
Answer:
125 = 
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x = 
Given
125 = 3, then
125 =
