2x²+2xy+yx+y²+2x²+2xy-yx+y²
2x²+2x²+2xy+2xy+yx-yx+y²+y²
2x²+2x²+2xy+2xy
4x²+4xy
Answer:
x = -2y + 12
Step-by-step explanation:
Let's solve for x.
x + 2y = 12
Step 1: Add -2y to both sides.
x + 2y + −2y = 12 + −2y
x = −2y + 12
Answer:
the answer is 12.24 .
Step-by-step explanation:
that answer is right is because when you add of those you get 530 , then you divide by how many numbers there are which is 7 , which equals to 75.7 . when you get that number ( 75.7) you subtract that number to 65,90,85,70,70,95, and 55 . when you get the total of all of those you add those . which is 10.7, 14.3 , 9.3 , 5.7 , 5.7 , 19.3 , and 20.7 . from adding those you get 85.7. you divide by 7 and get 12.24 . hope this helps :) .
1615/170
We first need to convert this into a proper fraction. Which means that the denominator must be larger than the numerator for it to be proper. Also, since 1615 is BIGGER than 170, we will end up with a mixed fraction. A mixed fraction always has a whole number.
1615 can go into 170 how many times?
9 times
170*9 = 1530
Now subtract.
1615 - 1530 = 85
Now we have our mixed fraction: 9 85/170
Now we must simplify the fraction.
85/5 = 17
170/5 = 34
17/34 is the smallest possible fraction we can get.
9 17/34
Final answer:
