Hannah played 4 songs in 5/8 hour.

castortr0y [4]

In 1 hour, Hannah will play 6 2/5 songs, or 32/5.

To get from 5/8 to 1, you have to multiply by the number 1 3/5 (5/8 • 1 3/5 = 1). So, you multiply 4 by 1 3/5 too. (4 • 1 3/5) This gets you to the final answer, 6 2/5.

Subtract 7x^2−5xy+8y2 from −2x^2−15xy+9y^2

Digiron [165]

Answer

Subtract $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$

then;

$-2x^2 -15xy+9y^2 - (7x^2 -5xy+8y^2)$

Remove the bracket we have;

$-2x^2 -15xy+9y^2 - 7x^2 + 5xy - 8y^2$

Like terms are those terms which have same variable to the same power.

Combine like terms;

$-9x^2 -10xy+y^2$

Therefore, Subtracting $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$ we get $-9x^2 -10xy+y^2$
