Problem 1) xy means "x times y". The multiplication symbol is left out because its implied. You can write x*y if you wish. Or we can say "product of two numbers" since a product in math terms is the result of multiplication.
---------------------------------------------
Problem 2) x/y means "x divided by y" which is a fraction
---------------------------------------------
Problem 3)
Writing "x-y" is the same as saying "x minus y"
---------------------------------------------
Problem 4)
x+y is "x plus y", or we can say "the sum of x and y". The "sum" is "result of adding two or more values"
---------------------------------------------
Problem 5)
y-x is "y minus x" or we can say "x subtracted from y"
---------------------------------------------
Problem 6)
y division symbol x is essentially the flip of problem 2. We'd say "y divided by x"
---------------------------------------------
Problem 7)
x+y = 6 is "the sum of two numbers is 6". See problem 4 above.
---------------------------------------------
Problem 8)
xy = 6 is "the product of two numbers is 6". This is an extension of problem 1.
---------------------------------------------
Problem 9)
6x = y is "six times a number equals y" when translated out
---------------------------------------------
Problem 10)
y = x-6 would translate to "six less than a number is y"
where the "a number" portion is represented by x
Answer:
400 ping pong balls
Step-by-step explanation:
Let the total number of ping pong balls =x
Out of x ping pong balls, 80 are marked with a blue dot
Out of 80 ping pong balls, 16 are marked with a blue dot.
Expressing it as a ratio:
x:80=80:16
There are an estimate of 400 ping pong balls in the container.
Basically, from what i can see and understand, is that you take the original price. lets use the chair.
$139.99 you choose which discount you would like to use either the $20 off or 20% off.
if you choose $20 then
$139.99-$20=119.99
but if you choose 20%
$139.99x0.20=27.99 (meaning you deduct $27.99 from $139.99)
139.99-27.99=$112
now you decide which one you'd choose. i would say 20% off because it costs less.
