Step-by-step explanation:
t in 1200m:
t in 3750:
difference is:
3.75-0.12 = 3.63
-6x>= -72. {x| 12>=x}
-72 (less than or equal to sign) -6x (product means multiply right?) all solutions is the value 12 and any value less
Answer: Choice C) -11
-----------------------------------
Explanation:
The first equation given is y = 3 - 1/2x
In other words, y is the same as 3 - 1/2x.
We can replace y in the second equation with 3 - 1/2x
This is known as substitution (think of a substitute teacher who is a temporary replacement for your teacher)
Doing this leads to...
3x+4y = 1
3x+4*y = 1
3x+4*( y ) = 1
3x+4*( 3 - 1/2x ) = 1 <<--- y has been replaced with 3-1/2x
3x+4*(3) +4*(-1/2x) = 1
3x+12-2x = 1
3x-2x+12 = 1
x+12 = 1
x+12-12 = 1-12 <<-- subtracting 12 from both sides
x = -11
Which is why the answer is choice C) -11
The volume is 240ft^3. v=Ah/3. v=(72)(10)/3. v=720/3. v=240.

I’m sure that is the answer because that is my topic too
