Answer:
Step-by-step explanation:
Given expression:
To write the given expression in single logarithm.
Solution:
We will apply the logarithm properties to write the expression in single logarithm.
We have:
Using power rule : [ 
]
⇒ 
Using product rule: [ 
]
⇒ 
Using quotient rule. [ 
]
⇒
Thus, we successfully converted the expression to a single logarithm expression.
Answer:
A. 24 in
Step-by-step explanation:
Because side GF was multiplied by 4, the rest can be calculated in that same manner.
Answer: 10 plants
Step-by-step explanation:
subtract 2.5 hours by 15 and you get 10.
Define your variables:
Q: number of quarters
D: number of dimes
Next, create your equations
Q = 2D-4
25Q+10D=200
Because one variable (Q) is already written in terms of the other variable, D, you can already start solving with substitution.
25(2D-4)+10D=200
50D-100+10D=200
60D=300
D=5
Substitute D back into the other equation to find Q.
Q=2D-4
Q=2(5)-4
Q=6
Substitute D and Q into the second equation to check.
25Q+10D=200
25(6)+10(5)=200
150+50=200
This works, so the answer is right! Bill has 6 quarters and 5 dimes.
