Answer:

12

Step-by-step explanation:

6 logs for 4 hours means that she needs 2/3 of a log each hour (4÷6 = 2/3). If she needs fire for 18 hours, then, 18 x 2/3 = 12

9 + n/2 &gt; 16<br>show work please
iVinArrow [24]

1. write the division as a fraction
9+n/2>16 → 9+1/2n>16
2. multiply both sides of the inequality by 2
2x9+2x1/2n>2x16
3. multiply the numbers and reduce the numbers with greatest common divisor 2 (remove number 2, the common factor from equation)
18+n>32
4. move constant to the right by adding its opposite to both sides
18+n-18>32-18
5. eliminate the opposites
n>32-18
6. subtract the numbers
n>14

Answer:

Betsy uses  8\frac{4}{10} gold to make the earrings

Step-by-step explanation:

Given:

Amount of gold with Betsy =  ten and one half ounces

Amount of gold Betsy used to make earrings =  four fifths  

To Find:

How much gold is used by Betsy to make earrings = ?

Then

X  =   four fifths  of  ten and one half

X  = \frac{4}{5} of 10 \frac{1}{2}

X = \frac{4}{5} \times \frac{20 + 1}{2}

X = \frac{4}{5} \times \frac{21}{2}

X=  \frac{84}{10}

Reducing the fraction to lower terms and converting into mixed fraction we get,

X=  8\frac{4}{10}

Answer:

<h2>h < 2</h2>

5(2h+8) < 60

10h + 40 < 60

Group like terms

10h < 60 - 40

10h < 20

Divide both sides by 10

h < 2
