Answer:
(i) 2x = 2 × x. 3x2 = 3 × x × x. 4 = 2 × 2. The common factor is 1. (ii) 6abc = 2 × 3 × a × b × c. 24ab2 = 2 × 2 × 2 × 3 × a × b ...
Step-by-step explanation:
Answer:
$140
Step-by-step explanation:
10 is 1/3 of x.
10=1/3x
x=30
x is 1/5 of y
30=1/5y
150=y
y-10=z
150-10=z
z=140
Answer:
Step-by-step explanation:
The answer is Since 0 in ln(3x) - 0 is not a logarithm, the property of logarithms cannot be used here.
The difference shown cannot be written as a quotient of logarithms.
The step ln(x2) = ln(3x) - (0) reduces to
ln(x2) = ln(3x).
The possible solutions are 0 and 3, with 0 being extraneous.
First find x: y= -2x+4 so you take that and substitute it into your second equation -x+3(-2x+4)=-9 ---> -7x+12=-9 ---> -7x= 3 ---> x=-3/7
Now you can find y by substituting x: y=-2x+4 ---> y=-2(-3/7) +4 ---> y=
