Answer:
is this by any chance about simultaneous equations? If so,
Step-by-step explanation:
Step 1 is telling us to decide on whether x and y should be the unknown. For instance, you want x to be the unknown, so u solve for x.
Step 2 is telling us to write equations with x and y.
For example,
7x + 5y = 12
7x - 2y = 9
This may not be accurate but it is an equation.
Step 4 is telling us to check whether the solution is accurate or not. For instance, we say 7 is x. so we substitude 7 into the original equation to see whether the answer we found is correct.
For step 5, im not really sure.
hope this helps though???

i think the answer should be 16
Answer: V=37.5 cm³
Step-by-step explanation:
Formula
V=(πr²h)/3
Given
r=5/2=2.5 cm
h=6 cm
Solve
V=(πr²h)/3
V=(π(2.5)²(6))/3
V=(π(6.25)(6))/3
V=37.5π/3
V=37.5(3)/3
V=37.5 cm³
Hope this helps!! :)
