Answer:
x = (y - b)/m
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First subtract b from both sides:
y = mx + b
y (-b) = mx + b (-b)
y - b = mx
Next, divide m from both sides:
(y - b)/m = (mx)/m
x = (y - b)/m
x = (y - b)/m is your answer.

Answer:
Length = 90 inch.
width = 30 inch
Let width of the rectangle = x inch.
So the length = 3x inch.
Perimeter = 2(length + width) = 2 (3x + x) = 8x.
So,
length = 3x = 3(30) = 90 inch.
width = x = 30 inch
Step-by-step explanation:
easy to look up : mili stands for 1/1000
so,
500 ml are 500/1000 liters.
25 ml are 25/1000 liters (a tiny glass).
and 1 Iiter is of course, 1000/1000 liters (1000 ml).
4 liters 500 ml are then
4×1000/1000 + 500/1000 = 4500/1000 l = 4500 ml.
how many glasses of 25 ml can be filled with that ?
this is the same question as into how many parts of 25 can 4500 be split ? or, how often does 25 fit into 4500 ?
all this is done by division :
4500 / 25 = 180
so, 180 of such glasses can be filled.
