The property used in making the above is the distributive property

Answer:

The first blank would be x=6

the other blank would be 9=4.5

Step-by-step explanation:

if you look at the table, you can see that when you insert a number as x (A.K.A the number "two") the number is divided by 2, so in the y row, its half the number that x was.

2÷1=1

4÷2=2

6÷2=3

7÷2=3.5

9÷2=4.5

Answer:

50 cookies

Step-by-step explanation:

We are told that Max made cookies and cupcakes in the ratio 4:5.

Now, we are told he 40 cupcakes were made.

Thus, by proportion we can find how many cookies were made.

Number of cookies made = 5 × 40/4 = 50 cookies

Answer:

The answer is below

Step-by-step explanation:

The question is not complete but I would solve a similar question:

Alexis needs to paint the four exterior walls of a large rectangular barn. The length of the barn is 80 feet, the width is 50 feet, and the height is 30 feet. The paint costs $28 per gallon, and each gallon covers 420 square feet. How much will it cost Alexis to paint the barn? Explain your work.

Solution:

The barn has four walls. Let the four walls be labeled as w, x, y and z.

The area of wall w = 80 feet * 30 feet = 2400 feet²

The area of wall x = 50 feet * 30 feet = 1500 feet²

The area of wall y = 80 feet * 30 feet = 2400 feet²

The area of wall z = 50 feet * 30 feet = 1500 feet²

The total area of the four walls = area of wall w + area of wall x + area of wall y + area of wall z

The total area of the four walls = 2400 + 1500 + 2400 + 1500 = 7800 ft²

Given that each gallon of paint can cover 420 feet². Therefore number of gallon needed is:

number of gallon needed = 7800 ft² ÷ 420 ft² per gallon = 18.57

Since the gallon must be a whole number and 18 gallons wont be enough, therefore number of gallon needed is 19 gallons.

Cost of painting = 19 gallons * $28 per gallon = $532

Answer:

6x - 5 ≥ 8

Step-by-step explanation:

Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?

The inequality sign of

a) At least = greater than or equal to = ≥

Let us represent the number as = x

Hence: "five less than the product of a number and 6 is at least 8" can be written as:

= x × 6 - 5 ≥ 8

= 6x - 5 ≥ 8

Step-by-step explanation:

For the first one the equation is Y=2x+2 because look at rise over run which is 4/2 which is 4 divided by 2 which is 2

so the answer is Y=2x+2

The second one is, the points are (2,2) (3,3)

Answer:

33

Step-by-step explanation:

So all the single-digit positive whole numbers that evenly divide 72 would be:

1 (72 / 1 = 72)

2 (72 / 2 = 36)

3 (72 / 3 = 24)

4 (72 / 4 = 18)

6 (72 / 6 = 12)

8 (72 / 8 = 9)

9 (72 / 9 = 8)

Then, 1 + 2 + 3 + 4 + 6 + 8 + 9 = 3 + 7 + 14 + 9 = 10 + 23 = 33

Answer:

x = -2

y = 8

Answer:

3:25 pm

Step-by-step explanation:

The distance between New Orleans and Houston is : 353 miles

Departure time of the bus : 12:20 pm

Speed of the bus: 60 mph

After 45 minutes, the bus will be at a distance of : 45/60 * 60 = 45 miles

Distance remaining to cover = 353-45 = 308 miles

Speed of the motorcycle = 72 mph

Relative speed = 60 + 72 = 132 mph

Time the two will meet = 308 / 132 =  7/3 hrs

7/3 hrs = 2 hrs  20 minutes

Time the two will meet is ;

12:20 pm + 45 minutes + 2 hrs 20 minutes

= 3:25 pm

Both the bus and the motorcycle are driving opposite to each other.

From the given data, the time at which both the bus and the motorcycle will pass each other is 3:25 PM

The time at which both the motorcycle and the  bus will pass each other.

Let after t hour from the time when motorcycle starts, they both meet.

Then we have:

353 miles = 45 minute traveled by bus + distance traveled by bus in t hour + distance traveled by motorcycle in t time.

Since 45 minutes is three fourth of an hour, thus:

Distance traveled by bus in 45 minutes is calculated as:

[tex]D_{Bus}(45 \:\rm min) = 60 \times \dfrac{3}{4} \: \rm miles = 45 \: \rm miles[/tex]

Distance traveled by bus in t hours is:

[tex]D_{Bus}(t \: \rm hours) = 60 \times t \: \rm miles = 60t \: \rm miles[/tex]

Distance traveled by motorcycle in t hour is:

[tex]D_{motorcycle}(t \: \rm hours) = 72 \times t \: \rm miles = 72t \: \rm miles.[/tex]

Thus, we have:

[tex]353 = 60t + 72t + 45\\\\308= 132t\\\\t = \dfrac{308}{132}\\\\t= \dfrac{7}{3}\: \rm hours\\\\t=2 \: \rm hours + 20 \: \rm minutes[/tex]

Thus, time at which they meet was 12:20 PM + 45 minutes + 2 hours + 20 minutes = 3:25 PM

Step-by-step explanation:

Answer:

Cost of one senior citizen ticket = $11

Cost of one child ticket = $12

Step-by-step explanation:

Let,

x be the cost of one senior citizen ticket

y be the cost of one child ticket

According to given statement;

3x + 3y = 69      Eqn 1

5x + 3y = 91      Eqn 2

Subtracting Eqn 1 from Eqn 2

(5x+3y)-(3x+3y) = 91 - 69

5x+3y-3x-3y = 22

2x = 22

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{22}{2}[/tex]

x = 11

Putting x = 11 in Eqn 1

3(11) + 3y = 69

33 + 3y = 69

3y = 69 - 33

3y = 36

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{36}{3}\\y=12[/tex]

Hence,

Cost of one senior citizen ticket = $11

Cost of one child ticket = $12

Step-by-step explanation:

Answer:

f(x)=-5(x-1)^2

Step-by-step explanation:

The given parent function is: f(x)=x^2

If we shift to the right by 1 unit, the function becomes: f(x)=(x-1)^2

If we stretch by a factor of 5, the function becomes, f(x)=5(x-1)^2

Finally reflecting over the x-axis gives: f(x)=-5(x-1)^2
