replace b with 7 so you must first multiply -3 by 7 which gives you -21. Subtract 25 more and you get -46, which is the answer.

Which expression is equivalent to 7 plus b-b?
7
What is 2a plus b?
2a+b=2a+b. Without a value for a and b, the expression has no value.
What is b2 plus 8b plus 7?
b2 + 8b + 7 is an expression that represents a number. The exact identityof that number depends on the value of 'b', and whenever 'b' changes, thenumber also changes.
What is the value of ab if a is 7 and b is 9?
a=7 b=9 ab=? ab is the multiplication of a & b there fore the value of ab=7*9=63
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 expression is equivalent to 7 plus b-b?
7
A plus b?
The value of a + b depends on the values of the individual variables.The expression a + b cannot be simplified.
-2 b -9?
7
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.
What is the algebraic expression for 7 less than b?
b-7
What is 2a plus b?
2a+b=2a+b. Without a value for a and b, the expression has no value.
What is b2 plus 8b plus 7?
b2 + 8b + 7 is an expression that represents a number. The exact identityof that number depends on the value of 'b', and whenever 'b' changes, thenumber also changes.
How do you solve this equation a plus 7 equals 10 plus b?
you can't get a value for either a or b from just the information you have given - you can only get an expression for what a is in terms of b and vice versa; a=3+b b=a-3
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!
How do you do this math problem?
to find b in y=25x + b you can substitute in one of the coordinate pairs for x and y. for example,you can substitute 7 for x and 175 for y.this gives 174=(25)(7) + b .solve this equation for b and substitute that value into the expression
What is the algebraic expression of seven less than a number b?
(b - 7) should do it.
What is 7 - b?
That depends what the value of b is.
