Answer:
150 mm^3
Step-by-step explanation:
The formula of a pyramid is
V=1/3(Bh)
The formula for a rectangle is
V=(Bh)
They both have the same Bh, so because the formula of a pyramid states that it's 1/3 of Bh, and 1/3 of Bh = 50, the volume of a whole Bh is 150mm^3.
Hope this makes sense
Answer: Choice D) ordered pair is <u>not</u> a solution to the second equation
We can see this by replacing x and y with 1 and -4 respectively
2x + y = 4
2*1 + y = 4 .... replace x with 1
2*1 + (-4) = 4 ... replace y with -4
2 - 4 = 4
-2 = 4 .... this equation is false because -2 and 4 are different values
The last equation being false means that the original equation 2x+y = 4 is also false when (x,y) = (1,-4). Therefore, this ordered pair is not a solution to the second equation 2x+y = 4
A solution to the system must make BOTH equations true simultaneously, not just one.

Answer:
x= 8 + 2y/3
Step-by-step explanation:
6x = 48+4y
x = 48/6 + 4y/6
simplify
x= 8 + 2y/3
