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.
Gifts Bags --> 6/7 hours
x = time together
[tex]\frac{1}{x}[/tex] = rate of completion
Aunt 1 = [tex]\frac{1}{1.5}[/tex] Grandma 1 = [tex]\frac{1}{2}[/tex]
[tex]\frac{2}{3} +\frac{1}{2} = \frac{1}{x}[/tex]
[tex]\frac{7}{6} = \frac{1}{x}[/tex]
[tex]x = \frac{6}{7}[/tex]
Centerpieces --> 7/4 hours
x = time together [tex]\frac{1}{x}[/tex] = rate of completion
Mom = [tex]\frac{1}{3.5}[/tex] Aunt 2 = [tex]\frac{1}{3.5}[/tex]
[tex]\frac{2}{7} + \frac{2}{7} = \frac{1}{x}[/tex]
[tex]\frac{4}{7} = \frac{1}{x}[/tex]
[tex]x = \frac{7}{4}[/tex]
Balloons --> 15/16 hours
x = time together [tex]\frac{1}{x}[/tex] = rate of completion
You = [tex]\frac{1}{1.5}[/tex] Grandma 2 = [tex]\frac{1}{2.5}[/tex]
[tex]\frac{2}{3} + \frac{2}{5} = \frac{1}{x}[/tex]
[tex]\frac{16}{15} = \frac{1}{x}[/tex]
[tex]x = \frac{15}{16}[/tex]
Shortest amount of time to complete all tasks is:
[tex]\frac{6}{7} + \frac{7}{4} + \frac{15}{16} = \frac{397}{112}[/tex] ≈ 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.
find x for -3+x=2(x+3)
Answer:
x = -9
Step-by-step explanation:
find x for -3 + x = 2 (x+3)
-3 + x = 2 (x + 3) <== distribute
-3 + x = 2x + 6 <== subtract 1x from both sides
-x -x
-3 = x + 6 <== subtract 6 from both sides
-6 -6
-9 = x or x = -9

Given Equation :

Solution :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad - \: 3+x=2(x+3)}}} \\ \\[/tex]
Using Distributive property for the right side we get :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad - \: 3+x=2x+ 6 }}} \\ \\[/tex]
Now, subtracting 2x from both sides we get :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad - \: 3+x - 2x =2x - 2x + 6 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad - \: 3- x = 6 }}} \\ \\[/tex]
Now, Adding 3 to both sides we get :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad - \: 3 + 3- x = 6 + 3 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad- \: x = 9 }}} \\ \\[/tex]
Now, Multiplying both sides by (-1) we get :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad (- 1)(- x) = ( - 1)9 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad x = - 6 }}} \\ \\[/tex]

[tex]\mathrm{1 \dfrac{ 1 }{ 6 }\:cups}[/tex]
Step-by-step explanation:
Given from the graph:
There is [tex]\frac{1}{2}[/tex] cups of paint for one jar
There are 3 cups of paint for three jars
There is 1 [tex]\frac{1}{2}[/tex] cups of paint for one jar
There is 2 cups of paint for one jar
total amount of jars = 6
But since we need to find the amount of cups in each jar, we do:
[tex]\dfrac{ 1 }{ 2 } +3+1 \dfrac{ 1 }{ 2 } +2[/tex]
Add [tex]\frac{1}{2}[/tex] and 1 [tex]\frac{1}{2}[/tex]
[tex]2+3+2[/tex]
Add 2 and 3
[tex]5+2[/tex]
Add 5 and 2
[tex]7[/tex]
total cups of paint = 7
Then we need to find how much paint could be splitted equally among the 6 jars, so we do the following:
total amount of jars = 6
total cups of paint = 7
We divide the total amount of jars by the total cups of paint
7 ÷ 6
Divide 7 by 6
[tex]\dfrac{ 7 }{ 6 }[/tex]
[tex]= 1 \dfrac{ 1 }{ 6 }[/tex]
[tex]\mathrm{Answer: 1 \dfrac{ 1 }{ 6 }\:cups}[/tex]
3. Use the GCF and the Distributive Property to factor, 60a + 45.
a. 3(20a +15)
b. 5(12a +9)
с. 20(За + 2)
d. 15(4a + 3)
Answer:
D. 15(4a + 3)
Step-by-step explanation:
15 is the least possible factorisation for both sides, therefore D is the most efficient on of all of them
Using the GCF and Distributive property, the expression can be factorized as, d. 15 (4a + 3).
What is GCF?GCF is the abbreviated form for Greatest Common Factor.
As the name suggests, GCF of two or more numbers or expressions is the greatest of all the common factors of them.
The given expression is 60a + 45.
Distributive property for 3 numbers, a, b and c states that,
a (b + c) = ab + ac
There are two terms here 60a and 45.
We can find the GCF using Prime factorization.
60 = 2 × 30
= 2 × 2 × 15
= 2 × 2 × 3 × 5
45 = 3 × 15
= 3 × 3 × 5
Common factors are 3 and 5.
GCF = 3 × 5 = 15
60a + 45 = (15 × 4a) + (15 × 3)
= 15 (4a + 3) [Using the distributive property]
Hence the factorized form is 15 (4a + 3)

How to find total Number ?A percentage is a number or ratio that is expressed as a fraction of one hundred. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.
A total is the result of adding several numbers together or counting how many items there are in a group. The total number or cost of something is the total number or cost obtained by adding or counting all of its parts.
Percentages can also be expressed as decimals or fractions, such as 0.6%, 0.25%, and so on. Academic marks are calculated in terms of percentages for any subject.
To Find the Total Amount :
In decimal form, identify the partial amount and the percentage of the partial amount.Percentage of partial amount in decimal form: 0.80 since 0.80 is the decimal form of 80%.Calculate the total amount by dividing the partial amount by the percentage of the partial amount.No. of student in seventh grade = 8/5 * 100 = 160

Which steps could be part of the process in algebraically solving the system of equations, y 5x = x2 10 and y = 4x – 10? select two options. y = x2 5x 10 y 5x = x2 10 4x – 10 0 = x2 – 9x 0 = x2 – 9x 20 one x-value of a solution to the system is 4.
Answer:
That would be :
4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y)
PROOF: y + 5x = x² + 10
(4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
0 = x2 – 9x + 20 (liked terms are grouped and simplified)
PROOF: 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5

Explanation:
The figure is an unfolded version of a pyramid, so it's placed as flat as possible.
The square in the middle has area of 7*7 = 49 square meters. This is the base or floor of the pyramid.
Each triangle has area of base*height/2 = 7*5/2 = 35/2 = 17.5 square meters. Four such identical triangles combine to an area of 4*17.5 = 70 square meters. This is the lateral surface area, which is everything but the base.
So the total surface area is
BaseArea + LateralSurfaceArea = 49+70 = 119 square meters

An airplane flies 2,070 miles in 4.5 hours. What is the speed of the airplane in miles per hour? Use the equation d=rt, where dis distance, ris rate, and t is time.
The airplane's speed is miles per hour.
Answer:
sorry but I actually don't know about it sorty
Answer:
460 miles/hour
Step-by-step explanation:
Distance = Speed x Time
We want the Speed, so let's rearrange the equation:
Speed = Distance/Time
We are given Distance = 2070 miles
and Time of 4.5 hours
Speed = (2070 miles)/(4.5 hours)
Speed = 460 miles/hour

Kira ran 8 1/5 miles in 69 7/10 minutes. What is Kira’s average time per mile?
Answer:
1 mile = 8.5 minutes
Step-by-step explanation:
Determining the equation:
Kira ran 8 1/5 miles in 69 7/10 minutes.
⇒ Kira = 8 1/5 miles = 69 7/10 minutes
⇒ 41/5 miles = 697/10 minutes
Simplifying both sides:
⇒ 41/5 miles = 697/10 minutes
⇒ 41 miles = 697/2 minutes
Using cross multiplication:
⇒ 41 × 2 miles = 697 minutes
⇒ 82 miles = 697 minutes
Dividing 82 both sides:
⇒ 82 miles = 697 minutes
⇒ 82/82 miles = 697/82 minutes
⇒ 1 mile = 8.5 minutes

slope of m1 = - coefficient of x / coefficient of y
= - 12 / -1
= 12

Answer:
[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + 3
Step-by-step explanation:
the coordinates of the points are
(1, - 6 ), (2, - 3 ), (3, 0 ), (4, 3 ), (5, 6 )
consider the values of y
- 6, - 3, 0, 3, 6
there is a common difference between consecutive terms, that is
- 3 - (- 6) = 0 - (- 3) = 3 - 0 = 6 - 3 = 3
this indicates the sequence is arithmetic with recursive rule
[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + d ( d is the common difference )
here d = 3 , then recursive formula is
[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + 3 ; with a₁ = - 6
