====================================
Explanation:
There are two ways to find the answer
Method 1: Take 15% of 11500 to get 0.15*11500 = 1725. This is the amount Emily pays, so she has 11500-1725 = 9775 dollars left over
Method 2: She pays 15% of her income, so she has 85% left over. This is because 100% - 15% = 85%. Now apply 85% to her income to get 0.85*11500 = 9775
Answer:
$97750
Step-by-step explanation:
Speed of a object is defined as the total distance covered in the total time taken. To run 11 miles Luke take 22 minutes longer than the colleen to run 11 miles.
Given information-
Luke can run a mile in 7 minutes.
Colleen can run a mile in 5 minutes.
Speed of a object is defined as the total distance covered in the total time taken. Speed is the ratio of the distance to the time taken . Thus,
As Luke can run 1 mile in 7 minutes. Thus the speed of the Luke is,
Thus the speed of the Luke is 1/7 miles per minute.
As Colleen can run 1 mile in 5 minutes. Thus the speed of the Colleen is,
Thus the speed of the Luke is 1/5 miles per minute.
The total time taken by the Luke to cover the 11 miles with the speed of 1/7 miles per minute is,
Solve for
Hence, the total time taken by Luke to run 11 miles is 77 minutes.
The total time taken by the Colleen to cover the 11 miles with the speed of 1/5 miles per minute is,
Solve for
Hence, the total time taken by Colleen to run 11 miles is 55 minutes.
Extra time taken by Luke to cover 11 miles than Colleen is,
Hence to run 11 miles Luke take 22 minutes longer than the colleen to run 11 miles.

Answer:
4b + 6
Step-by-step explanation:
Every variable that stands by it self is counted as one. 3b is 3b because it tells you. Since there’s two “b” variables you add them together making 3b + b= 4b and since the 6 doesn’t have a variable you don’t add it to the 4b making your final answer 4b+ 6

A.
5 7/9 yards
B.
5 5/9 yards
C.
5 5/3 yards
D.
5 1/3 yards
Casey bought a total of 5 5/9 yards of fabric (yellow and purple combined). The pair of scissors does not count towards the total yardage of fabric.
The first step is to add the amount of yellow and purple fabric that Casey bought. So we have 2 2/3 yards of yellow and 3 1/9 yards of purple fabric, which gives us a total of 5 5/9 yards of fabric (Since 2 2/3 equals 8/3 and 3 1/9 equals 28/9, when we add them we have 8/3 + 28/9 = 56/27, which simplifies to 5 5/9). The pair of scissors does not count towards the amount of fabric bought, so it can be disregarded for this question. Thus, the correct answer is B. 5 5/9 yards.
