Question

Evaluate 6x+9/3xy if x=6 and y=4

Answer 1

Explanation:

To evaluate the expression 6x + 9 / 3xy, we can substitute the given values of x = 6 and y = 4 into the expression. Let's start by replacing x and y in the expression:

6(6) + 9 / 3(6)(4)

Now, let's simplify the expression using the order of operations (PEMDAS/BODMAS):

First, we'll multiply 6 by 6:

36 + 9 / 3(6)(4)

Next, we'll multiply 3 by 6 and 4:

36 + 9 / 72

Now, let's divide 9 by 72:

36 + 0.125

Finally, we'll add 36 and 0.125:

36.125

Therefore, when x = 6 and y = 4, the value of the expression 6x + 9 / 3xy is 36.125.

Answer 2

• 
  `(5)/(8) \\`

Task :

• To evaluate 6x + 9/3xy when x = 6 and y = 4

Solution :

All we need to do in the evaluation process is plug in the values of x and y in the expression.

• 
  `\rightarrow \: (6x + 9)/(3xy) \\`
• 
  `\rightarrow \: (6(6) + 9)/(3(6 * 4)) \\`
• 
  `\rightarrow \: (36 + 9)/(3 * 24) \\`
• 
  `\rightarrow \: (45)/(72) \\`
• 
  `\rightarrow \: (9 \: . \: 5)/(9 \: . \: 8) = (5)/(8) \\`

Thus, 5/8 is the value we get by evaluation of 6x + 9/3xy when x = 6 and y = 4.
