Please help me with this! Also, if you can, what are prime numbers? I need to understand! 0-0
Answer:
9
Step-by-step explanation:
So a prime number is any number that can only be divided by 1 and itself. 7, 3, and 13 are all prime numbers.
Hope i could help you
Answer: 9
Step-by-step explanation:
a prime number is a number which has factors as one and itself.
All the numbers when multipled by 1 give the same number and no other two numbers hanging multiply it.
But for 9,1*9 gives 9 and 3*3 gives 9

Why do equivalent ratios form a straight line when graphed?
The vertical distance between points is constant, and the horizontal distance between points increases with each point.
The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.
The horizontal distance between points is constant, and the vertical distance between points increases with each point.
The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.
Answer:
D-The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

The length of a rectangle is given by x + 2 and its width is equal to 3. Give a simplified expression of the area of this rectangle.
Answer:
3x+6 sq units
Step-by-step explanation:
3(x+2) = 3x + 6
Answer:
➥ Area of rectangle = (3x + 6) units²
Step-by-step explanation:
Length of rectangle = (x + 2)
Width of rectangle = 3
\Large{\underline{\mathfrak{\bf{\orange{Find}}}}}
Area of rectangle
\Large{\underline{\underline{\mathfrak{\bf{\red{Explanation}}}}}}
Important Formual
\bigstar\small\boxed{\tt{\green{\:Area_{rectangle}\:=\:(Length\times Width)}}}
So, Now
➥ Area of rectangle = ( x + 2) * 3
➥ Area of rectangle = (3x + 6) units²

The angle measures of a triangle are shown in the diagram below. What is the value of x?
Answer:
30°, see explanation below!
Step-by-step explanation:
Hewo Again!
And for your question.
All of the inside angles of a triangle added together equals 180°!
So:
2x+2x+2x=180
6x=180
x=30°
Answer:
30
Step-by-step explanation:
i believe it is 60 because an equilater triangle like that has its angles as 60° and 60 ÷ 2 is 30.
Hailey used 2 2/3 liters of cola to completely fill 2 bottles. If the bottles are all the same size, how many liters of cola does each bottle hold? Enter your answer below
Answer:
they each hold 1 1/3 litters of cola
Step-by-step explanation:
Because if there is 2 2/3 liters of cola
then you either divide it by 2
or you can look at it and see what would add evenly to make that number
in this case it would be 1 1/3
1 1/3 +1 1/3= 2 2/3
please mark me as brainliest
hope this helps!
Please help ASAP ASAP ASAP asap
Answer:
2 would be on the top
10 would be on the bottom
1 would be way on the bottom
then the remainder will be 1

GCf of 90 & 45
Whats 7 divided by 3/5
Answer:
11.6 with a repeating 6 or 11 2/3
Step-by-step explanation:
i am the swagster!!!
Pls help me. I'm begging TwT
Answer:
the answer is 46
Step-by-step explanation:
4×28/ 7×1 = 112/7
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
We already did that, and the GCF of 112 and 7 is 7.
We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.
112/7 = 16
and do the same for 3/4 out of 16 then add ur answers

Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.
Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5
Jaxon is creating a mosaic design on a rectangular
table. He has added two pieces to one of the corners.
The first piece has an angle measuring 38° and is
placed in the corner. A second piece has an angle
measuring 27° and is also placed in the corner. Draw a
diagram to model the situation. Then, write an
equation, and use it to determine the measure of the
unknown angle in a third piece that could be added to
the corner of the table.

pls help it should be ez for u guys
Answer: 950.3
Step-by-step explanation:
so the formula for the volume of a sphere is 4/3*pi*r^3
so plugging your information into the formula, you would get 4/3(pi)(6.1)^3
6.1^3 is the same as
(6.1) times (6.1) times (6.1)
this equals 226.981
now you have 4/3(pi)(226.981)
now you do 226.981/3 which equals 75.660333
multiply that by 4➡️ 302.6413333333333
now you have to multiply by pi (3.14)
302.6413333333333*3.14=
950.2937866666667
you have to round to the 10ths place
so your answer is 950.3 m cubed.

Can you please help?
the points (-9,-3) and (-2,r) fall on a line with a slope of 1/7. What is the value of r?
If its not right im gonna report you
Answer:
R = -2
Step-by-step explanation
-9, -3 is the first point.
A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.
-9 - 7 = -2
-3 - 1 = -2 (r)
with a slope of 1/7, (-9, -3) connects to (-2, -2)
Pls mark me brainliest if right thank you
