Evaluate 3x + 5 y when x=11 and y =4
To evaluate 3x + 5y when x = 11 and y = 4, substitute the values of x and y into the expression:
3(11) + 5(4)
Simplifying the expression:
33 + 20
The result is:
53
To evaluate 3x + 5y when x = 11 and y = 4, we substitute the given values into the expression.
First, substitute x = 11 and y = 4 into 3x:
3(11) = 33
Next, substitute x = 11 and y = 4 into 5y:
5(4) = 20
Finally, add the two values together:
33 + 20 = 53
Therefore, 3x + 5y evaluates to 53 when x = 11 and y = 4.
To evaluate the expression 3x + 5y when x=11 and y=4, you need to substitute the given values into the expression and perform the necessary calculations.
Step 1: Substitute the values of x and y into the expression:
3x + 5y = 3(11) + 5(4)
Step 2: Multiply each term by the corresponding coefficient:
3(11) + 5(4) = 33 + 20
Step 3: Perform the addition operation:
33 + 20 = 53
So, when x=11 and y=4, the value of the expression 3x + 5y is 53.
