Answer:
d
Step-by-step explanation:
it's 4 because I'd you put the numbers from least to greatest its in the middle
Step-by-step explanation: The base of the power in the original equation becomes the base of the log. So we have 
.
Next, the exponent in the original equation goes on the other side of the equation and finally, the result in the original equation goes inside the log.
So we have 
which is 3² = 9 written in logarithmic form.
This can also be switched around to read 
.
So the first choice will be your answer.
My work is also show in the image attached,
I just didn't switch it.
Answer:
£30
Step-by-step explanation:
To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.
1 : 6 = 1 + 6 = 7 parts
Now divide the total amount of parts by the total amount of money shared
35 / 7 = 5
Now multiply the answer by the value that is appropriate.
In this case, they want you to work out how much Ali recieved.
Ali's value is 6
6 × 5 = £30
hope this helps :)
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.
X = 4 AND x = -9
Good luck.
