4A = 5B.
For finding the ratio A to B take B to the left side of the equation and 4 to the right side.
4 X A = 5 X B ( 4 multiplied by A = 5 multiplied by B)
When any number goes to the other side you need to change the sign from + to - or / to X and vice versa. So when we take B to the left side it carries the / sign. Similarly with 4 )
A/B = 5/4 ( The ratio of A to B )

Solve this equation using addition method 4a subtract 5b equals 7 and 4a plus 5b equals 17?
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
What does ab over b divided by 4a over 5b equal?
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
What is 5ab plus 4a-b-2ab plus 5b?
5ab-2ab+4a-b+5b = 3ab+4a+4b
What is the rational expression of the quotient 4a plus b and 2a - 5b?
The expression is: (4a+b)/(2a-5b)
What is b when 5b equals 30?
If: 5b = 30 Then: b = 6

What is a ratio of 4 to 5?
A ratio of 4 to 5 is equivelant to saying there are "4 of object A's for every 5 object B's". For example, there may be a ratio of 4 to 5 of red and black marbles in a bag. For every 4 red marbles are in the bag, there are 5 black marbles. Therefore, if there were 12 red marbes in a bag, there would be 15 black marbles in the bag. A= object A; B= object B 4A=5B; A=5B/4 or B=4A/5
What is the order pair for 4a - 5b equals 7 and 4a plus 5b equals 17?
Simultaneous Equations 4a - 5b = 7 4a + 5b = 17 Add the two , this will eliminate 'b' 8a = 24 Divide both sides by '8' a = 3 When a= 3 , substitute into eityher equation for 'b'. 4(3) + 5b = 17 12 + 5b = 17 5b = 17 - 12 = 5 5b = Divide both sides by '5'. Hence 'b = 1'.
What is b when 5b equals 30?
If: 5b = 30 Then: b = 6
Simplify fully 4a plus 5b minus 2a plus b?
2a+6b
What is 4a equals 4-b 4a equals 2-b?
They appear to be the equations of two parallel lines in the a-b plane.
10a-5b equals 25 what is b?
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
What is 27 equals b plus 5b?
b= -162
Find the area of a rectangle that has a base of 5 m and a height of 4a plus b m?
Area = base * height = 5*(4a + b) m2 = (20a + 5b) m2
