round 19 in 120 to the nearest tenth cause the tenths place is bigger than 5 19 = 20 so 120 divided by 6=20
Answer:
C. 2x + 12
Step-by-step explanation:
2(10) + 2(x-4)
= 20 + 2x - 8
= 2x + 20 - 8
= 2x + 12
In matrix form, this is
The coefficient matrix has determinant
so it has an inverse, which is
Multiply both sides by the inverse matrix:
so that 
and 
.
Answer:
Step-by-step explanation:
It really depend what number, or what type of number you are multiplying, it's kind of like multiplication you're just doing it backwards. Say that you were trying to divide 20 by 5 you think in your head OK five times what equals 20 and your answer would be four because 5×4 is 20 that's the easiest way to think of it that did not help you with your question tell me in the comments and I will find a better way to explain it.
