devlian [24]

Answer:

9/32 of the cookie was left for Stephanie to eat after lunch

Step-by-step explanation:

Anastasia’s mom baked a giant sugar cookie for her birthday.

On her birthday, ⅝ of the birthday cookie was eaten.

So, remaining cake =1 - \frac{5}{8}=\frac{3}{8}

The next day her brother ate ¼ of what remained.

Amount of cake eaten by her brother = \frac{1}{4}(\frac{3}{8})=\frac{3}{32}

So, remaining cake = \frac{3}{8}-\frac{3}{32}=\frac{12-3}{32}=\frac{9}{32}

Hence 9/32 of the cookie was left for Stephanie to eat after lunch

How do you solve #4 with a proportion
Irina-Kira [14]
The clothes weigh 14.77 kilograms.

Given:
Weight of suitcase = 50 pounds
Towels = 20% of weight
Shoes = 15% of weight
Clothes = 65% of weight

convert pounds to kilograms using proportion:

<u>pounds</u>        <u>2.2</u> = <u>50</u>
kilograms       1           x

2.2x = 50 ⇒ x = 50/2.2 ⇒ x = 22.73 kgs

Clothes : 22.73 kgs * 65% = 14.77 kgs
Towels  : 22.73 kgs * 20% =   4.55 kgs
Shoes   : 22.73 kgs * 15% =   3.41 kgs

Subtract <br><br> \frac{3n+2}{n-4}-\frac{n-6}{n+4}
aalyn [17]
(3n+2)/(n-4) - (n-6)/(n+4)

common denominator (n-4)(n+4)

{(n+4)(3n+2)-(n-4)(n-6)}/{(n-4)(n+4)}

Use the foil method:

{(3n²+14n+8)-(n²-10n+24)}/{(n-4)(n+4)}

distribute negative sign:

{(3n²+14n+8-n²+10n-24)}/{(n-4)(n+4)}

subtract:

(2n²+24n-16)/{(n-4)(n+4)}

take out 2:

2{n²+12n-8}/{(n-4)(n+4)}
