Stella is making 25 sundaes with mint, chocolate, and vanilla ice cream. 1 5 of the sundaes are mint ice cream and 1 2 of the re
o-na [289]

Answer:

Vanilla = 10 sundaes

Step-by-step explanation:

Total sundaes = 25

1/5 of the sundaes are mint ice cream

Mint ice cream = 1/5 of 25

= 1/5 * 25

= 25/5

= 5

Sundaes remaining = total sundaes - sundaes for mint ice cream

= 25 - 5

= 20 sundaes

Sundaes remaining = 20 sundaes

1/2 of the remaining sundaes are chocolate

= 1/2 of 20

= 1/2 * 20

= 20/2

= 10

Chocolate ice cream = 10

The rest will be vanilla

Sundaes remaining = 20 - 10

= 10 sundaes

Vanilla = 10 sundaes

Write out   5t^2                    3t                            5t^2
                 -------- .  Invert --------- and multiply ---------- by the result:
                  8x^2                 (x^2)                         8x^2

                5t^2
multiply ---------- by the result:      5t^2       5*x^2     25 t^2 x^2
                8x^2                            ------- * ---------  = ----------------
                                                    8x^2         3t         8x^2 (3t)

Reducing this, we get       25t

HELP ASAP
Schach [20]

Answer:

Step-by-step explanation:

(a). A_{1} = x ( 2x + 1 ) = <em>2x² + x</em>

(b). A_{2} = 2( 2x + 1 )( 5x + 3 ) = <em>20x² + 22x + 6</em>

(c). A_{3} = 20x² + 22x + 6 - ( 2x² + x ) =

( 20x² - 2x² ) + ( 22x - x ) + 6 =

<em>18x² + 21x + 6</em>
