Answer:

12,24,24

Step-by-step explanation:

60(.2)=12 that means the beginner is 12 trails leaving you with 80% left so you split it evenly each of the other 2 gets 40% of the total trails making it 24 and 24 to double check this you can add them up 24+24+12=60 which is true

The route to an ancient pyramid is 79 miles long.
Nostrana [21]

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let the distance travelled in the first day be 20 miles. If the same time was travelled for 3 days, hence:

3(20) + x = 79

x = 19 miles

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

Jenny is selling chocolate bars it for each bar she sells she makes two dollars profit she wants to use The money she earns I’m
andre [41]

Answer:

Yes

Step-by-step explanation:

Since Jenny makes a profit of $2 for each bar of chocolate that she sells, if she sells a total of 500 chocolate bars, her profit would be:

Profit for 500 chocolate bars = profit for each chocolate bar * 500 bars

Profit for 500 chocolate bars = $2 per bar * 500 bars

Profit for 500 chocolate bars = $1000

Also she want to buy a laptop worth $998. This would be possible after selling 500 bars because $1000 > $998. After buying the laptop she would have $2 remaining ($1000 - $998)

Rewrite the expression using the Distributive Property.
Nostrana [21]
The Distributive Property states: a(b+c) = ab+ac.

5(6+12) is the expression.

5•6+5•12 is the product of the Distributive Property.

30+60 is the product of multiplication.

Therefore, 30+60 is the correct answer.

• We just distributed the 5 to the 6 and 12 because the entire expression of 6+12 is being multiplied by the 5, hence there are parentheses.
