Lets do a simple two step equation
For example,
2x-8=12
Our main goal is to get the X value alone.
In order to do this, We will subtract 8 from both sides.
Our equation will now look like:
2x=20
In order to get the X alone here, We have to divide 2x by 2 in order to cancel out the 2 out. This means that since we divided by 2 on one side, we have to do it on the other.
Our equation now looks like:
x=10
Step-by-step explanation:
multiply both sides by 4,
3x+1=-2x-12
5x+1=-12
5x=-11
x=-11/5
Answer:
The surface area is 48cm^2
Step-by-step explanation:
Given
Dimension: 2cm by 2cm by 5cm
Shape: Rectangular Prism
Required
Determine its Surface Area (A)
This is calculated as thus:
Where l, w and h are the dimensions of the given shape:
We can say:
So:
<em>Hence, the surface area is 48cm^2</em>
Answer:
-5/-6
Step-by-step explanation:
Use the equation rise over run, which is also y2-y1 over x2-x1
in basically every type of thing, x always comes first then y
y2=1 y1=6 x2=-2 x1=-4
1-6/-2-(-4)=-5/-6, because it was changed to, -5/-2+4
Answer:
1-4y+y
1-3y
