Alright, so first we'll have to get y on the other side
So
2x+y=-9
-y -y
+9 +9
2x+9=-y
Then divide is all by -1 so y is positive
-2x-9=y

Answer:
2
Step-by-step explanation:
The best mechanical advantage you can get is obtained by pushing the door at its edge. If the door's center of mass is halfway from the hinge to the edge, then the advantage you get (in terms of force reduction) is ...
1/(1/2) = 2
Answer:
x=10-6
x=4
Step-by-step explanation:
for which level
Answer: T = 4
Step-by-step explanation:
1. Write all the variables down
P = 8 V = 2X N = 2 R = 2X X = 3
2. Since you know that X = 3 substitute it in to find V and R
V = 2X = 2(3) = 6
R = 2X = 2(3) = 6
3. Find PV
PV = P x V
= 8 x 6
= 48
4. Find NRT
NRT = N x R x T
= 2 x 6 x T
= 12 x T
= 12T
5. Find T
PV = NRT
48 = 12T
12T = 48
divide both sides by 12
T = 48 ÷ 12
T = 4
