How do you evaluate the variable expression 3a plus 2b?
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.
What is b- 5 answer?
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.
Which is the value of 3b to the second - b when b5?
-2
How do you rationalize the denominator in this expression 3 over quantity of 6 minus square root of 5?
Multiply the expression (fraction) by (6 + √5)/(6 + √5) (which is 1 and will not change its value).3/(6 - √5) x (6 + √5)/(6 + √5)= 3(6 + √5)/(6 - √5)(6 + √5)= 3(6 + √5)/(36-5) = 3(6 + √5)/31= 3/31(6 + √5)Remember:(a + b)(a - b) = a2 - ab + ab - b2= a2 - b2So if either a or b contains a square root, a2 and b2 will not, and so a2 - b2 will not!
How can you write the expression a plus b plus a-b in equivalent form not involving absolute value.?
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
Which is the value of 3b - b when b 5?
-2
3 times the sum of b and 5?
The algebraic expression is 3(b+5).

What is the value of the expression when a 0 and b 3?
It would depend on the expression that you have in mind but chose not to share!

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.
What is algebraic phrase?
Algebraic phrase is a mathematical expression which substitutes characters and letters for a certain numeric value. For example a=b+c, if b=2 and c=3, then a=5.
What is five divided by the sum of a and b?
You can write that as 5 / (a + b), or as a fraction, with the 5 on top, and a + b at the bottom. The actual value of this expression will depend on the values of "a" and "b".
Which is the value of 3b to the second - b when b5?
-2
A verbal expression for 5 a-b?
A verbal expression for 5 a-b is that it is 5 is multiplied by the difference between a and b.
How do you rationalize the denominator in this expression 3 over quantity of 6 minus square root of 5?
Multiply the expression (fraction) by (6 + √5)/(6 + √5) (which is 1 and will not change its value).3/(6 - √5) x (6 + √5)/(6 + √5)= 3(6 + √5)/(6 - √5)(6 + √5)= 3(6 + √5)/(36-5) = 3(6 + √5)/31= 3/31(6 + √5)Remember:(a + b)(a - b) = a2 - ab + ab - b2= a2 - b2So if either a or b contains a square root, a2 and b2 will not, and so a2 - b2 will not!
If the expression 5x 3 2 is written in the form ax b what is the value of a plus b?
The values of a and b would be assumed to be 3 and 10 or 2 and 15.
A plus b?
The value of a + b depends on the values of the individual variables.The expression a + b cannot be simplified.
