Evaluate the expression for
A=4 B=2
3(a+7)-4b
First, substitute the given values for A and B into the expression:
3(4+7)-4(2)
Next, perform the calculations inside the parentheses:
3(11)-4(2)
Multiply 3 by 11:
33-4(2)
Multiply 4 by 2:
33-8
Finally, subtract 8 from 33:
25
Therefore, the expression 3(a+7)-4b with A=4 and B=2 evaluates to 25.
To evaluate the expression 3(a+7)-4b for A=4 and B=2, you need to substitute the values of A and B into the expression and perform the calculations step by step. Here's how you can do it:
Given: A=4, B=2
Expression: 3(A+7)-4B
Step 1: Substitute the values of A and B into the expression:
3(4+7)-4(2)
Step 2: Simplify the expressions inside the parentheses:
3(11)-4(2)
Step 3: Perform the operations inside the parentheses:
33-8
Step 4: Multiply and subtract:
33-8 = 25
Therefore, when A=4 and B=2, the expression 3(a+7)-4b evaluates to 25.
To evaluate the expression 3(a+7)-4b, substitute A=4 and B=2.
First, substitute the value of A:
3(4+7)-4b
Next, substitute the value of B:
3(4+7)-4(2)
Now, simplify the expression inside the parentheses:
3(11)-4(2)
Evaluate the multiplication first:
33-8
Finally, perform the subtraction:
25
Therefore, the value of the expression 3(a+7)-4b when A=4 and B=2 is 25.
