Answer: 4/15
Step-by-step explanation:
-1/3 - -3/5
Two negative signs become positive so it's
-1/3+3/5
Taking the LCM as 15,
-1/3= -5/15
3/5= 9/15
-5/15 + 9/15
= (-5+9)/15
= (9-5)/15 ( just changing the order without changing the sign)
= 4/15
This is the simplest form
(If you need it in decimal form is 0.26666... or 0.267)

T=log(15,400÷1,200)÷log(1.04)
T=65 years
Hmmm I think 16 - 10 = 10 ( - 8 - 6 ) = 6
Answer:
So it gives you a little picture and tells you what would the question be if you had this graph.
Step-by-step explanation:
The correct answer would be B, find the area because the 4x + 3 is your length and 3x is your length, A = length * width. So the answer is B, find the area.
Answer:
a) 7/4 b) 5 c) 2
Step-by-step explanation:
Logrithmic Rule for a and b
Let a, M, N be positive real numbers.
a)
logaM - logaN = loga(M/N)
log9(7) - log9(4) = log9 (7/4)
b)
logaM + logaN = logaMN
log2 (x) + log2(9) = log2(45)
x9=45
(x9)/9 = 45/9
x = 5
c)
Change of base formula.
logb(x)=logd(b)/logd(x)
x log6(5) = log6(25) divide each term by log6(5)
x log6(5) / log6(5) = log6(25) / log6(5) Cancel common factor log6(5)
x = log6(25) / log6(5)
x = log6(5^2) / log6(5)
Expand log6(5^2) by moving 2 outside the logarithm.
x = 2log6(5) / log6(5) cancel the like term log6(5)
x = 2
