The answer is n=3. 4 also has a variable in front of it so (4n) which shows you have to multiply. 2 + 6 give you 8 but 2x3+6 gives you 12, 4 x 3 also gives you twelve so your answer is n=3
Answer:
89
Step-by-step explanation:
Given that Wendy took 2 tests and scored, 77 and 80 respectively, let x represent the grade of Wendy's third test.
To get an average grade of 82, let's generate an equation to find x (Wendy's grade on her third test).
Average grade = sum of all 3 grades all over 3
![82 = \frac{77 + 80 + x}{3}](https://tex.z-dn.net/?f=%2082%20%3D%20%5Cfrac%7B77%20%2B%2080%20%2B%20x%7D%7B3%7D%20)
![82 = \frac{157 + x}{3}](https://tex.z-dn.net/?f=%2082%20%3D%20%5Cfrac%7B157%20%2B%20x%7D%7B3%7D%20)
Multiply 3 by both sides
![82*3 = \frac{157 + x}{3}*3](https://tex.z-dn.net/?f=%2082%2A3%20%3D%20%5Cfrac%7B157%20%2B%20x%7D%7B3%7D%2A3%20)
![246 = 157 + x](https://tex.z-dn.net/?f=%20246%20%3D%20157%20%2B%20x%20)
Subtract 157 from each side of the equation
![246 - 157 = 157 + x - 157](https://tex.z-dn.net/?f=%20246%20-%20157%20%3D%20157%20%2B%20x%20-%20157%20)
![89 = x](https://tex.z-dn.net/?f=%2089%20%3D%20x%20)
Wendy must score 89 on her third test to have an average of 82.
Answer:
B
Step-by-step explanation:
mrk me brainliest plz
Let x be the no. of oranges and y be the no. of tangerine.
From question, we get,
4y = x
=> 4y = 8260
=> y = 8260/4
=> y = 2065
Therefore, the farmer shipped 2065 tangerines
