In algebra, the expression "b - 5" represents the subtraction of 5 from the variable b. This means you are taking away 5 units from the value of b. The result will depend on the specific value of b. For example, if b = 10, then b - 5 would equal 5.
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
Evaluate -4(a+b) - 10a/b when a=8 and b=5
The expression is: 5(b + x)
To evaluate the variable expression 3a + 2b, you need specific values for the variables a and b. Once you have those values, you substitute them into the expression and perform the arithmetic operations. For example, if a = 4 and b = 5, then 3(4) + 2(5) = 12 + 10 = 22. This gives you the final value of the expression.
