Using the Distributive Property write an equivalent equation: 6(x+7)
Answer:
6x+42
Step-by-step explanation:
By using Distributive Property we distribute 6 by multiplying both x and 7 by 6
(6*x)+(6*7)
6x+42
Answer:
6x+42
Step-by-step explanation:
if you multiply a number in this case 6 by a pharenthesis you have to multiply that number by each term inside the pharenthesis.
6(x+7) is 6*x +6*7 = 6x+42

. Fiona has 18 red carnations, 27 white carnations, and 36 blue carnations. She wants to make arrangements of red, white, and blue carnations.She plans to use all of the flowers and to have the same number of each color in each arrangement. If she makes the greatest number of arrangements possible, then how many blue carnations will be in each arrangement?
Answer:
9 blue carnations.
Step-by-step explanation:
Given that,
Fiona has 18 red carnations, 27 white carnations, and 36 blue carnations. She wants to make arrangements of red, white, and blue carnations.
If she makes the greatest number of arrangements possible, then we need to find how many blue carnations will be in each arrangement.
Greatest possible arrangements = HCF of 18,27 and 36
The factors of 18 are: 1, 2, 3, 4, 6, 9, 12, 18,
The factors of 27 are: 1, 3,9,27
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The greatest common factor = 9
For blue carnation,
B = (36/9) = 4
Hence, in each arrangements there are 9 blue carnations.
Which of the following are solutions to the equation below?
Check all that apply.
x2 + 4x-9 = x + 1
A. 2
B. 4
C. -7
D. -5
E. -3
F. -4
Answer:
A.2
Step-by-step explanation:
X is equal to 2
If you plug in 2 for X both sides will equal each-other
2(2) + 4(2)-9 = (2) + 1
4 + 8 - 9 = 3
12-9 = 3
3 = 3
Therefore X is equal to 2

On a map, every 0.5 cm represents 25 km. If. London is 454 km away from Paris, about how far apart from each other do the cities appear on the map?
Answer: pretty sure it's c: 908cm
Step-by-step explanation:
454÷25= 18.16 and 18.16÷0.5= 908
Here we need to perform a change of units, from real distances to distances in a map.
We will find that the distance on the map is 9.08cm
Let's see how to get that.
First, the information that we have is:
Each 0.5 cm in the map represent 25 kmLondon is 454 km away from Paris.The first thing we need to find is how many times we have 25km in 454km, we will get:
n = 454km/25km = 18.16
Each one of these 18.16, is represented with 0.5cm in the map, then the distance in the map is:
distance = 18.16*0.5 cm = 9.08cm
The distance on the map is 9.08cm

Step-by-step explanation:
Applying altitude- on - hypotenuse theorem.
(leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 3 × (3 + 7) = 3 × 10 = 30 ( take square root of both sides )

In 2011, a professional climber scaled the outside of Burj Khalifa making it all the way to 828 meters in 6 hours. how far did they climb in the first 2 hours?
Given:
Professional climbers climb 828 meters in 6 hours.
To find:
how far did they climb in the first 2 hours?
Solution:
According to the question,
In 6 hours, they climb 828 meters.
In 1 hour, they climb [tex]\dfrac{828}{6}[/tex] meters.
In 2 hour, they climb [tex]2\times \dfrac{828}{6}[/tex] meters.
Now, the distance they climb in the first 2 hours is
[tex]\text{Climb in first two hours}=2\times \dfrac{828}{6}[/tex]
[tex]=\dfrac{828}{3}[/tex]
[tex]=276[/tex]
Therefore, they will climb 276 meters in first 2 hours.
The sum of two numbers is less than 2. If we subtract the second number from the first, the difference is greater than 1. What are the two numbers?
Answer:
the value of these two numbers are 1/2 and 3/2
Step-by-step explanation:
Given that:
x+y < 2 ---- (1)
y - x > 1 ---- (2)
From equation (2), let y > 1 + x then substitute it into equation (1)
x + 1 + x < 2
2x + 1 < 2
2x < 2 - 1
2x < 1
x < 1/2
From equation (2), replace the value of x to be 1/2
y - 1/2 > 1
y > 1 + 1/2
y > 3/2
Find the equation of the line parallel to y = x - 3 that also intersects the point (3,-2).

Y= 1x+-5

a. -1=x^2: One solution because only -1 will satisfy the equation.
b. -1=x^2: No real solution because there is no real number that, when squared, produces -1.
C. 1=x^2: Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1=-x^2: One solution because only -1 will satisfy the equation.
1=x²: two solutions because the square root of 1 is positive 1 and negative 1
Answer:
B. -1 = x^2; No real solution because there is no real number that, when squared, produces -1

2 prime numbers are represented by f and g what is the greatest common factor of f and g please answer this fast its for a timed test
Answer:
1
Step-by-step explanation:
The greatest common factor of f and g is 1.
What is the greatest common factor?The greatest number can divide the numbers into equal parts.
It is called the greatest common factor.
Given:
2 prime numbers are represented by f and g.
That means the numbers are only factored by 1 and the number itself.
Let f = 2 and g = 3
Here, 2 and 3 are the prime numbers.
The GCF of 2 and 3 is 1.
That means the numbers are only factored by 1 and the number itself.
So, the greatest common factor of f and g is 1.
Therefore, 1 is GCF.

A 400 kg box and a 200 kg are to pushed across a horizontal table, the exact same distance with the exact force. Which box will have the most work done on it? Which box will get to the end first? Explain both of your responses.
Answer:
Both boxes have the same amount of work applied to them. The smaller box will get to the end first.
Step-by-step explanation:
For the 400 kg box, we can say,
force = 1 newton
force = mass*acceleration
1 = 400*acceleration
acceleration = 1/400 meters per second^2
acceleration = 0.0025 meters per second^2
Each second, the larger box's velocity is increasing by 0.0025 meters per second.
While the smaller box would have an acceleration of...
force = 1 newton
force = mass*acceleration
1 = 200*acceleration
acceleration = 1/200 meters per second^2
acceleration = 0.005 meters per second^2
Which is twice as much as the larger box.
Put simply: if the force applied is the same for the two boxes, then the smaller box will have larger acceleration. This is because more force is needed to push on the larger mass.
Because the smaller box has more acceleration, it will naturally travel faster compared to the larger box. Therefore, the smaller box reaches the goal line faster.
A half-circle is joined to an equilateral triangle with side lengths of 12 units. What is the perimeter of the resulting shape? Write your answer as a decimal rounded to the nearest tenth. Do not include the label.
Answer:
P = 42.84 cm
Step-by-step explanation:
A half-circle is joined to an equilateral triangle with side lengths of 12 units.
We need to find the perimeter of the resulting shape.
The perimeter of the half cirle is πr.
The diameter of the circle is 12. It means radius is 6 units.
An equilateral triangle has 3 equal sides. So, perimeter of the triangle is given by :
P = πr + 12 +12
= 3.14(6) + 24
= 42.84 cm
Hence, the perimeter of the resulting shape is 42.84 cm.
