I would add like terms, meaning subtract 6.4 from both sides.

3.5n = 36.1

<h2>Answer:</h2>

n= 361/35

alternative forms:

n= 10 11/35 or n= 10.3142857

<h2>Step-by-step explanation:</h2>

3.5n+6.4=42.5

move constant to the right

3.5n=42.5-6.4

subtract 42.5 to 6.4

3.5n=36.1

divide both sides by 3.5

----------------

n=361/35

PLEASE HELP ME:complete the chart to compare the distance each ballon moved from the dasged line

So D would be going up because it is positive. It is going up 10ft, once again cause the integer is a positive 10. Now E will be going down because it is a negative. Therefore it will go down 15ft for the reason being the integer is negative 15. Hope this helps.

SHORT ANSWER Graph and label point W(4, –1) <br> on the coordinate plane.

Lunna [17]

Answer:

Step-by-step explanation:

a coordinate point is (x, y) so for point W (4, -1), 4 is the x-coordinate and -1 is the y-coordinate.

Start at the origin (O). Go 4 units to the right (along the x-axis in a positive direction) and then 1 unit down (in the y plane in a negative direction).
