2n+=16
n difference of nine.
Well the word difference means in mathematical terms, The result of subtracting one number from another. How much one number differs from another.
<span>Example: The difference between 8 and 3 is 5.
I think the answer to your question is : 4&5
The reason why becuase 4+5 is 9 which are the 2 closest numbers to make nine and 2n+9=11+4+5=20 minus 2 two times and you will still get 16.
I hope this helped you! :)</span>
Answer:
.79
Step-by-step explanation:
You multiply 1.89×2 to get 3.18. Then you subtract 3.78 by 2.99 and get .79
4x + y = 7
y = -4x + 7
using y = mx + b
b being your y intercept, (0,7)
5/6x + 7 = 12 - 5/12x
subtract 7 from each side
5/6x = 5 - 5/12x
add 5/12x to each side
5/12x + 5/6x = 5
Find common denominator
5/12x + 10/12x = 5
combine like terms
15/12x = 5
divide each side by 15/12 (multiply the reciprocal)
x = 5 × 12/15
x = 60/15
x = 4
