The middle square has an area of 1 square unit. What is the area of the entire rectangle in square units? Explain your reasoning.
Answer:
4

what is the value of y when: -5=y-7over 9
Answer:
y=-38
Step-by-step explanation:
Undo the things that are being done to the variable.
1: Multiply both sides by nine to undo division.
-45=y-7
2: Add 7 to both side to undo the subtraction.
-38=y
Thats your answer!
Answer:
the answer should be -38 which is option c.
Step-by-step explanation: To get the answer first of all try a number that could be -7 -7 which would be -14 dividing by 9 making the results to be -1.55 or -1.56. So using the same steps trying to find the other answers what is the value of y and if you want use the process of elimination choosing an answer to eliminate and a reason why to eliminate it making it to option c which is the correct answer so sorry if i answer late and please give brainliest to the other people that answer first.

Find the measures of center and then type a numerical answer only (do not round).
Answer:
Mean: 13.5°
Median: 13.5°
Mode: 21°
Midrange: 13°
Step-by-step explanation:
Mean: Add all of the values together and divide by 8 (the number of values). This is also called average.
Median: The middle value when ranked lowest to highest. In this case there are an even number of values (8), so you have to use the average of the middle two, which are 12 and 15.
Mode: This is the most commonly appearing value, and in this case 21 is the only value that appears twice.
Midrange: To find this you add the highest and lowest values together and divide by two. In this case, those values are 5 and 21.
