Answer:
Anything. Variables look like anything, because a variable is just a placeholder for whenever you want to put in another number.
Some examples: x, y, Ф, β
Answer:
m = (y-6)/x
Step-by-step explanation:
To solve for m we want to get m by itself on one side of the equals sign, with everything else on the other side. First we subtract b from both sides, to get it out of the right side of the equation:
y - 6 = mx + 6 - 6
y - 6 = mx
Now we divide both sides by x, to get m completely by itself:
(y-6)/x = (mx)/x
(y-6)/x = m
So m is equal to (y-6)/x.
Answer:
Step-by-step explanation:
A store has a 20% sale on everything.
So since you are saving 20%, you will only be paying 80% of the original price.
To find the sale price use the following formula:
Sale price = 80% x original price
They told us the original price = 350 AED
This means:
Sale price = 80% x 350
I think it would be easiest to change 80% into a fraction if you don't have a calculator :)
80% = 
This means that the
Sale Price= 
x 350 = 280 AED
