Answer:
(hope this helps can I pls have brainlist (crown) ☺️)
Step-by-step explanation:
7^8 x 7^3 x 7^4 / 7^9 7^5
= 7^(8+3+4) / 7^(9+5)
= 7^15 / 7^14
= 7^(15-14)
= 7.
When the bases of the numbers are the same when multiplying numbers with exponents, you can just add the exponents like so:
7^8 x 7^3 x 7^4= 7^15
Now, look at the rest of the simplified equation and do the same to the denominator:
7^15 / 7^9 x 7^5 ⇒ 7^15/ 7^14
When the bases are the same in the fraction, you are allowed to subtract the exponents. This will lead you to the simplified answer = 7^15-14 = 7^1 = 7

Step-by-step explanation:
Answer:
Restaurant: 10%
Florist: 10%
Cab Fare: 0%
Dog Grommer: 5%
Step-by-step explanation:
Essentially, the question is asking us to round each of the tax percentages.
So, let's go through each of the services and round the tax to a reasonable number.
Restaurant:
The tax here is 8.5%.
Rounding to 5% would be a bit too low, and 20% would be too high. So, the only reasonable estimate here is 10%.
Florist:
The tax here is 12%.
Rounding to 5% would be too low, and 20% would be too high.
10% is just a bit lower, so it's the most reasonable.
Cab Fare:
The tax here is 0%.
Since it's at 0, there's no need to add anything to it. So, it would just stay 0.
Therefore, the most reasonable estimate is 0%.
Dog Grommer:
The tax here is 5.75%.
Again, 0% is too low, 10% is a bit too high, and 20% is <em>way</em> too high.
So, the only reasonable estimate is 5%.
And we're done!
The <em>correct answer</em> is:
The first number is 0.062.
Explanation:
Let x represent the first number in the list.
We add 0.001 to each number to find the next number; this gives us:
x + 0.001 + 0.001 = 0.064
Combining like terms, we have:
x + 0.002 = 0.064
Subtract 0.002 from each side:
x + 0.002 - 0.002 = 0.064 - 0.002
x = 0.062
