Answer:
64
Step-by-step explanation:
4 students were absent and that's 1/3 of class 4x4x4= 64
subtract 3 from both sides:

Multiply both sides by 2:

Subtract 3 from both sides:

Change sign to both sides (this implies that you should also change the inequality sign):

Answer:
y=-2+4
Step-by-step explanation:
we know the y intercept is four, so we can plug that into y=mx+b
so far we know y=mx+4
and the equation for finding slope is 
so let's find two points on the graph
let's make it easy on ourselves and use the points laid out for us
(0,4) and (2,0)
solving that would come out to be 
simplified, that would be -2
now that we know the slope, we can put them into slope-intercept form
y=-2+4
If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
First 0-0=0
Next 5-5=0
Then 4-3=1
After 3-1=2
Then 1-1=0
Move comma after 2
