Answer:
-4a-3
Step-by-step explanation:

1. Collect like terms
(n - 0.3n) + (4.5 - 3)
2. Simplify
0.7n + 1.5
Final Answer:
0.7n + 1.5
The answer is y = 6
Step-by-step explanation:
The formula of a slope:
We have the points (-5, 6) and (7, 6). Substitute:
The slope m = 0. Therefore it's a horizontal line y = a.
In the given points we have y = 6.
Ok we can simplify the ratio 10 and 15 by dividing both terms by the greatest common factor which is 5 Ok. So 10 divided by 5 is 2 and 15 divided by 5 is 3 therefore the answer is 2 : 3
X=4
Step-by-step explanation:
Solve for x by moving all terms to the left side
7x+9=13+6x
subtract 6x from both side
7x+9-6x=13
subtract 6x from 7x
x+9=13
subtract 9 from both sides
x=4
