Two positive numbers have a difference of 8 and a product of 48 Find the two numbers?
This problem can be solved with a system of equations. Let the first number equal x and the second number equal y. Here are the two equations: x-y=8 This makes sense because if two number have a difference of 8, than the first number minus the second number will equal 8. x * Y = 48 This is self explanatory. Now, we solve: x-y=8 x=8+y (y is added to both sides. Now we know what x is equal to, so we can substitute it into the second equation) (8+y)*y=48 8y+y2=48 (y is distributed) y2+8y-48=0 (the equation is made into a quadratic) (y+12)(y-4)=0 (the equation is factored) We know y is equal to four and not -12 because both number are positive. Now we solve for x: x-4=8 x=12 Therefore, your two number are 12 and 4.
What is 35 percent of a number if 12 is 15 percent of a number?
12=(15/100)x x=[(12)(100)]/15=(20)(4)=80 Now, 35 percent of a number is (35/100)(80)=Y after cancelling, Y=(7)(4)=28 OR (Shorthand Version) 12/.15=80 80(.35)=28

If x is 90 percent of y then y is how much percent of x?

Is x percent of y equal to y percent of x?
Let [x percent of y] = (x/100)*y. And [y percent of x] = (y/100)*x.Use the ruSo the first one (x/100)*y = y*(x /100) = y*x/100.The second one: (y/100)*x = x*(y/100) = x * y / 100, which equals y*x/100.So yes they equal the same thing, so they are equal.

What number times y equals 48?
To find the number that, when multiplied by ( y ), equals 48, you can express it as ( x \cdot y = 48 ). To solve for ( x ), you can rearrange the equation to ( x = \frac{48}{y} ). Therefore, the number is ( \frac{48}{y} ).

What are the two numbers whose sum is twelve and whose difference between their squares is forty eight?
4 & 8 Watch me closely. X + Y = 12 AND X^2 - Y^2 =48 Solve 1st equation for X ; X = 12 - Y Substitute into 2nd equation [12 - Y]^2 - y^2 = 48 144 - 24Y + Y^2 - Y^2 = 48 144 - 24Y = 48 24Y = 96 Y = 4 and X = 8
