Answer:
; 
Step-by-step explanation:
Score of the first two quizzes: 75 and 97
Let n represent the third score
Average score would be: 
.
Given that the average score fall between 85 and 90, this can be represented by the compound inequality as shown below:
Solve for n in each statement that makes up the compound inequality:
Multiply both sides by 3
Subtract 172 from each side of the inequality
Also,
Multiply both sides by 3
Subtract 172 from both sides of the inequality
Combining both together, the possible values of her third quiz score would be:
Well we know that he sold 20 glasses every hour. if h is the number of hours he worked we know the expression would be 20h
1 hr = 20 glasses
2 hr = 40 glasses
3 hr = 60 glasses
Keep the pattern going to figure out which hour he got his 100th glass sold.
8 I don’t know how to explain but the answer is
8
Elena's height in centimeters is 142.24 cm.
Elena's height in meters is 1.42 meters.

The mathematical operations that would be used to determine the answers ae division and multiplication.
Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Multiplication is the operation that is used to determine the product of two or more numbers.
In order to determine the height in centimeters, first determine how many cenitmeters make 1 inch
1 inch = 254 / 100
1 inch = 2.54 cm
Now, convert 56 inches to cm : 56 inches x 2.54 = 142.24 cm
In order to determine the height in meters, first find the unit of conversion of inches to meters
1 inch = 0.0254 meters
0.0254 x 56 = 1.42 meters
