2544.69m^3 sorry i don’t know to the nearest tenth place :(
Step-by-step explanation:
=> -3x - 4 = -5y - 8
=> 8 - 4 = 3x - 5y
=> 4 = 3x + (-5)y
=> 1 = (3x/4) + (-5y/4)
=> 1 = x/(4/3) + y/(-4/5)
Compare this with x/a + y/b = 1 where a and b are x & y intercepts.
Here,
x intercept = 4/3
y intercept = -4/5
Answer:
y=3
-47.5
Step-by-step explanation:
I did it in my notebook.
Add up 3+2+4=9 and the answer would 2/9 because the denominator represents all the shirts and the numerator is the specific shirts
We write system of equations:
O = 5*a
P = 15*a
a,b,c =?
------------------
a + b + c = 5a b + c = 4a
a*b/2 = 15a b/2 = 15
Now we calculate b and remaining sides:
b = 30
30 + c = 4a
c^2= 30^2 + a^2
(4a - 30)^2 = 900 + a^2
16a^2 - 240a + 900 = 900 + a^2
15a^2 = 240a
a = 16
that means that c = 4*16-30 = 34
