Which of the equations are true identities?

Klio2033 [76]

Answer:

Equation A is true; Equation B is not

Step-by-step explanation:

There is a standard formula for the "difference of cubes" that is:

x^3 - y^3 = (x - y)(x^2 + xy + y^2)

and this perfectly matches equation A.

Equation B has the square of n (n^2) on the left side but not on the right side. Thus this is not an identity.

The ratio of money in Obi's wallet to Rudy's wallet one day was 5:2.

mamaluj [8]

Answer:

The amount that Obi initially had was £20

Step-by-step explanation:

Let

x ----> amount that Obi initially has

y ----> amount that Rudy has

we know that

$\frac{x}{y} =\frac{5}{2}$

$x=2.5y$ ----> equation A

$x-20=y-8$

$y=x-20+8$

$y=x-12$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$y=(2.5y)-12$

solve for y

$2.5y-y=12\\1.5y=12\\y=8$

Find the value of x

$x=2.5(8)=20$

therefore

The amount that Obi initially had was £20
