Answer:
; 
Step-by-step explanation:
we know that
step 1
Find the inequality of the solid line x+3y=6
The solution is the shaded area below the solid line
therefore
The equation of the inequality is

step 2
Find the inequality of the solid line y=3x-1
The solution is the shaded area above the solid line
therefore
The equation of the inequality is

therefore
The system of linear inequalities is
; 
Answer:
it is the second one
Step-by-step explanation:
Okay so what we need to do is simplify 2/50, which is 1/25.
Now divide 25 into 1.
Which we will get 0.04
Now we need to move the decimal 2 times to the right.
It will be 4%
Or just multiply it by 100 and you will get 4%.
Answer:
Well, the only thing you should do is to use the formula.
if the bases are: a, b
and the height is=h
Then, this is your formula, S=½(a+b)×h
Step-by-step explanation:
Aight,
100dm=10m
S=10m
now, the formula
10=½(2.1+1.9)×h===> 20=4h==> h=5m
Answer:
60 I think
Step-by-step explanation:
draw a straight line to make it a triangle then you know that angles in a triangle add up to 180.
so,
180-140=40
180-100=80
40+80=120
180-120=60
x=60
I think it's 60
