Answer:

n=-5

Step-by-step explanation:

12+3n=-3

3n=-15

n=-5

First, you subtract 12 from both sides of the equation. Now, you should have 3n=-15. Next, you divide 3 on both sides of the equation to get your answer of n=-5

Question 1 Answer:

Aunt 1 and Grandma 1 would fill gift bags.

Mom and Aunt 2 would make centerpieces.

You and Grandma 2 would blow up balloons.

Since you are pairing up to complete the tasks, these pairs each have the shortest times in their respective categories and therefore are the most logical pairing to complete tasks.

Question 2 Answer:

We use algebra and our previous pairings to determine the length of each task.

<u>Gifts Bags --> 6/7 hours</u>

x = time together

\frac{1}{x} = rate of completion

Aunt 1 = \frac{1}{1.5} Grandma 1 = \frac{1}{2}

\frac{2}{3} +\frac{1}{2} = \frac{1}{x}

\frac{7}{6} = \frac{1}{x}

x = \frac{6}{7}

<u>Centerpieces --> 7/4 hours</u>

x = time together    \frac{1}{x} = rate of completion

Mom = \frac{1}{3.5} Aunt 2 = \frac{1}{3.5}

\frac{2}{7} + \frac{2}{7}  = \frac{1}{x}

\frac{4}{7} = \frac{1}{x}

x = \frac{7}{4}

<u>Balloons --> 15/16 hours</u>

x = time together    \frac{1}{x} = rate of completion

You = \frac{1}{1.5} Grandma 2 = \frac{1}{2.5}

\frac{2}{3} + \frac{2}{5}  = \frac{1}{x}

\frac{16}{15} = \frac{1}{x}

x = \frac{15}{16}

Shortest amount of time to complete all tasks is:

\frac{6}{7} + \frac{7}{4} + \frac{15}{16} = \frac{397}{112}  ≈ 3.54 hours

Converting hours to hours and minutes --> 3 hours 32 minutes

Therefore they must arrive by 5:28pm to complete the tasks in time to leave at 9:00pm.

frank reasoned that in the number 0.555, the valueof the 5 in the thousandths place is ten times the value of the 5 in the hundr
ollegr [7]

The reasoning of Frank is not correct. The value of 5 is the thousandths place is 1/10 times the value of 5 in the hundredths place instead of being 10 times.

In the question, we are given the number 0.555.

We can write it as:-

0.555 = 0.500 + 0.050 + 0.005

0.500 is the value of tenths place

0.050 is the value of hundredths place

0.005 is the value of thousandths place

We know that,

0.050*(1/10) = 0.050/10 = 0.005

Hence, the value of 5 is the thousandths place is 1/10 times the value of 5 in the hundredths place.

Please can someone help me work out the missing length​
Otrada [13]
Vol=area x Height

length= 3
breadth= X
Height = 2

area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so

42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7

so the missing length is 7cm
