Answer:
12 =x
Step-by-step explanation:
We can use proportions to solve
6 x
---- = -------
10 10+10
Using cross products
6 ( 10+10) = x*10
6*20 = 10x
120 = 10x
Divide by 10
120/10 = x
12 =x
Answer:
i am sure it is 142
Step-by-step explanation:
Answer:
−5x − 2y − 3
Explanation:
2x + 5 − 3y − 7x + y − 8
= 2x + 5 + −3y + −7x + y + −8
[ Combine Like Terms ]
= 2x + 5 + −3y + −7x + y + −8
= (2x + −7x) + (−3y + y) + (5 + −8)
= −5x + −2y + −3
Keeping in mind that i² = -1,


recall that a factor of the expression, gives a remainder of 0, and this one doesn't.
