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.
To find the expression ( 5abc ) for a variable ( a ), you need to substitute the value of ( a ) into the expression. For example, if ( a = 2 ), then ( 5abc = 5 \cdot 2 \cdot b \cdot c = 10bc ). If ( a ) has a different value, simply replace it in the expression accordingly.
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)
The expression is: (4a+b)/(2a-5b)
(a - b + 2)(a + b + 2)
The question contains neither an expression nor an equation (or inequality). There can, therefore be no sensible answer.
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
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.
2b -5 = -3
The equation cannot be solved as there are two unknowns. However it can be simplified and the two unknowns (a and b) expressed in terms of the second unknown. 1) Expressing a in terms of b 4a + 2 = 3b - 5 4a = 3b -7 if desired this could be stated as a = (3b - 7)/4 2) Expressing b in terms of a 3b - 5 = 4a + 2 3b = 4a + 7 if desired this could be stated as b = (4a + 7)/3
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".
i d know
A verbal expression for 5 a-b is that it is 5 is multiplied by the difference between a and b.
Area = base * height = 5*(4a + b) m2 = (20a + 5b) m2
4a² - b² = (2a + b)(2a - b)
