1. Combine like terms, so add 2.4 to -4.8 to get -2.4
So now you should be left with .02(x+20)-2.4=-9
2. Now eliminate the -2.4 by adding 2.4 to both sides, getting .02(x+20)=-6.6
3. Multiply everything by 50 to make x+20=-333, since 50×.02=1
4. subtract 20 from both sides to get x=-353
Here,
In Right angle triangle,
base = 12 m
height = 8 m
Now,
◇ Area = 1/2*b*h
= 1/2*12*8
= 48 m^2
In semicircle,
radius = 4 m
Then,
◇Area" = 1/2*22/7*r^
= 1/2*22/7*4*4
= 25.14m^2
Again,
◆Total Area = Right triangle + semicircle
= (48+25.14) m^2
= 73.14 m^2
This is right answer...

Step-by-step explanation:
Let a be the total score of Div. A
Let b be the total score of Div. B
given,
as equation 1.
and
as equation 2.
Now multiply equation 2 by 1/20 to eliminate b to solve for a.
take this new equation as equation 3.
now we will use equation 1 + equation 3 to eliminate b to solve for a.
Div.A total score = 600
Average Score = Total Score / Number of students.
Answer:
860
Step-by-step explanation:
32% of 860 = 275.20
You can't simplify this equation anymore because they have no like terms.
