If x+y=10 and x-y =6 what is the answer of x cube - y cube fast​
AfilCa [17]

Answer:

x+y=10 which means that x=10-y

Replace 10-y in the other equation which gives you:

10-y-y=6

10-2y=6

-2y=-4

y=2

Replace 2 in any of the 2 equations same answer for both:

x+y=10

x+2=10

x=8

So,

{x}^{3} - y^{3}

=  {8}^{3}  -  {2}^{3}

=512-8

=504

Hope this helps!

What is 3.24 repeating as a fraction
Amiraneli [1.4K]

Answer:

81/25

Step-by-step explanation:

Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

3.24/1 = (3.24 × 100)(1 × 100) = 324/100.

(324÷4)(100÷4) = 81/25 when reduced to the simplest form.   It's also equal to 3 6/25  or 81/25
