Skyler's age is 72 and Kori's age is 24.

Step-by-step explanation:

Step 1: From the given details, form equations. Let the age of Skyler be x and that of Kori be 96 - x (since their sum is 96).
Step 2: Considering their ages 8 years ago, form equations.

⇒ (x - 8) = 4 (96 - x - 8)

⇒ (x - 8) = 4 (88 - x)

⇒ (x - 8) = 352 - 4x

⇒ 5x = 360

⇒ x = 72

Step 3: Calculate Kori's age

⇒ 96 - x = 24

Molly owes her brother $300.She works for $10 per hour as a checker at the local grocery store.Molly plans to repay her brother

gavmur [86]

Answer: The expression which represents the condition described is given as $4x=300$

Step-by-step explanation:

Since we have given that

Amount that Molly owes her brother = $300

Let the number of hours she worked as a checker be x

Cost of per hour = $10

Amount she get after doing work for x hours is given by

$10x$

Rate of tax are taken out = 80%

So, amount she left with is given by

$\frac{100-20}{100}\times 10x\\\\=\frac{80}{100}\times 10x\\\\=8x$

So, Molly plans to repay her brother half of what she earns is given by

$\frac{8x}{2}=4x$

According to question,

$4x=300\\\\x=\frac{300}{4}\\\\x=75\ hours$

So, the expression which represents the condition described is given as

$4x=300$

hammer [34]

Area of circle = $\frac{ \theta }{360^o} \times \pi r^2 \\ 36 \pi = \frac{60^o}{360^o} \times \pi r^2 \\ r^2=216 \\ r= \sqrt{216} =14.70 \ cm \\ r=15 \ cm \ to \ the \ nearest \ whole \ centimeter.$
