Answer:
18 machines
Step-by-step explanation:
Data provided in the question:
It takes 4 machines 6 days to produce x units
Therefore,
it will take 4 machines 18 days to produce 3x units
let it takes Y machines 4 days to produce 3x units
Thus,
4 × (18 days) = 3x .............(a)
Y × (4 days) = 3x .............(b)
equating equation a and b, we get
or
4 × (18 days) = Y × (4 days)
or
Y = 18
Hence,
18 machines are required to produce a total of 3x units of product P in 4 days
Let's do this using the process of elimination. Since you didn't include choice D, we can only use A, B, and C.
C: If we're finding the width of the patio, how is the thickness of the tiles going to help? C is wrong.
A: We already know the area (72), so how does knowing the perimeter help us? All we know using that information is that 2 pairs of numbers give us the perimeter & also multiply to get 72. But not <em>which</em> 2. A is wrong.
B: Pay more attention to the last part of B... "the length". Well, if we have the area (72), and we have the length, then we can do area/length-width to find the width. B is correct!

Answer:
Step-by-step explanation:
Here you go mate
Use PEMDAS
Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction
Step 1
4n-9=2(5+2n) Equation/Question
Step 2
4n-9=2(5+2n) Remove parenthesis
4n-9=4n+10
Step 3
4n-9=4n+10 Subtract 4n to sides
-9=10
Step 4
-9=10 Add 9
0=19
Answer
No solutions
