Answer:
2.16
Step-by-step explanation:
r = cost of ruler
p = cost of pencil
r = 2p
6r + 15p = 2.16
Substitute 2p in place of r in 2nd equation and solve for p
6(2p) + 15p = 2.16
12p + 15p = 2.16
27p = 2.16

What is 3 ln 3 - ln 9 expressed as a single natural logarithm
Since ln (m^n) = n⋅ln (m) … natural logarithmic property
We can further simplify the expression 3 ln 3
3 In 3 = In (3^3)
Therefore, 3 ln 3 - ln 9 = In (3^3) – In 9
Since ln(m/n) =ln(m) – ln(n) … natural logarithmic property
We can further simplify the expression In (3^3) – In 9
In (3^3) – In 9 = In [(3^3)/(9)]
= In (27/9)
= In 3
Therefore, 3 ln 3 - ln 9 expressed as a single natural logarithm is In 3.

Answer:
triangle = 8
Step-by-step explanation:
The right side can be factored so that you have ...
8 x 4 = (triangle x 7) - (triangle x 3)
8 x 4 = triangle x (7 - 3) . . . . use the distributive property
8 x 4 = triangle x 4 . . . . . . simplify
8 = triangle . . . . . . . . . . divide both sides by 4
Answer: 4/5
Step-by-step explanation:
0.8 is 8 tenths which is 8/10 in fraction form
8/10 with both sides divided by two is 4/5
