Answer:
a. 
Step-by-step explanation:
First step is ti distribute the exponent outside the parenthesis. According to the law of exponents, you need to distribute it to each variable.
Now again, following the law of exponents, if you have negative exponents, you put them in the opposite side of the fraction.
Next, when it comes to division, we subtract the exponents of the numerator and the denominator of similar variables.
Since the exponent of x is negative, we move it below the fraction.
The answer is 0.015625, so no, it is not greater than 1
7, 207
7 = thousands place
2 = hundreds place
0 = tens place
7 = ones place
You want to round to the nearest thousand, the 7 all the way on the left is the number you're looking for.
Next, the number to the right of it, is it higher than 5 or lower than 5?
Since the number on the right is lower than 5 (it's a 2 - in the hundred's place), you round down to 0. If it was higher than 5, you round the 7 in the thousands place to an 8.
<h2>7.207 rounded to the nearest thousand is 7,000</h2>
Actually, it is
pages left=total pages-pages read
pages read=(number of pages per hour) times (number of hours)
numbe rof pages per hour=40
x=number of hours
254=total pages
so
y=254-40x, not 4x
what is the question
if it is how many hours to read the book then
0=pages left
0=254-40x
add 40x to both sides
40x=254
divide by 40
x=6.35
6.35 days or aprox 7 days
equation is y=254-40x where y=pages left and x=number of hours read
The answer is D because if you add 4 7/10 which is 4.7 and add 5 4/5 which is 5.8 it is 4.7 plus 5.8. That equals 10.5 which is equal to the answer of 10 1/2. If this is right could I possibly get brainliest?
