Emily's unit rate in miles per hour can be found by using the expression 9 ÷ (3/4) or 9 x (4/3). When calculated, we find that Emily is biking at a rate of 12 miles per hour.
To find Emily's unit rate in miles per hour, we need to divide the total miles she biked by the time it took her in hours. In Emily's case, she biked 9 miles in 3/4 hours. So the expression she can use to find her unit rate in miles per hour is 9 ÷ (3/4). Dividing 9 by 3/4 is the same as multiplying 9 by the reciprocal of 3/4, which is 4/3. So, the expression can also be written as 9 x (4/3). If we calculate that, we get 12. So, Emily biked at a rate of 12 miles per hour.

Answer:
Hello there!
Divide 9 by 3 to get 3.
Then use that to multiply 3 by 4 to get 12.
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
The degree is the highest exponent , in which in this problem it is 4. The 3x counts as an exponent of 1 because the variable x is 1, and the 2 counts as an exponent of zero. Which means the degree is 4.
The simplest form of 1.6 is 5/8
What is simplest form ?
In mathematics, the simplest form is the fraction that has the smallest equivalent value.
Here, the given decimal number is 1.6 :
and to find its simplest form we put the same number of zeros as the numbers after decimal in the given number that is one zeros :
1.6 = 16/10
Now, dividing it by common factor that is 2 :
16/10 = 8/5
Therefore, the simplest form of 1.6 is 5/8
