Absolute value equations : solve for all values of y in the simplest form.
21=|7y|
All values of y in the simplest form are 3 and -3
How to solve for all values of y in the simplest form?The equation is given as
21 = |7y|
The above equation is an absolute value equation
When the above equation is expanded, we have the following equations
So, we have
-21 = 7y and 21 = 7y
Divide both sides of the equations by 7
So, we have
-3 = y and 3 = y
Rewrite as
So, we have
y = -3 and y = 3
Hence, all values of y in the simplest form are 3 and -3

Answer:
x = 64
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees, so the missing angle in the triangle on the right has an angle measurement of 180 - 47 - 81 = 52 degrees.
Since the angle and the rightmost angle in the triangle on the right are vertical angles. They are congruent.
Finally, since the triangle on the left is an isosceles triangle and the base angles, the angles on the top left and bottom left, are congruent and therefore their angle measures are both x degrees. So, 2x + 52 = 180 and x = 64.
(HELP) The town of Miami is mapped on a coordinate
grid with the origin being at City Hall. Jordan's house
is located at the point (-5, 7) and Ca'Miyah's house is
located at (-2, 3). To the nearest tenth, How far is it
from Jordan's house to Ca'Miyah's house?
(51)
Answer: 5.2
Step-by-step explanation:
If we put both points on a grid, Jordan's house would be 4 points above and 3 points to the left of Ca'Miyah's. We can plug these two amounts into the pythagorean theorem to find the distance between the houses: 4^2 + 3^2 = x^2. If we solve this equation, we get 5.196, which rounds to 5.2.

find both area and perimeter of square its length is 16 cm
Answer:
Perimeter=16cm
Area=16cm
Step-by-step explanation:
we know that all 4 sides of square are equal. So,
Length of 4 sides of square= 16cm
Length of 1 side of square= 16/4cm=4cm
Now that we have found the length of single side of square, by using the formula of area and perimeter we can get of square like this:
Perimeter= 4 times the length of square
or,Perimeter= 4*4
Therefore,Perimeter=16 cm
Now,
Area=square of length of side
or,Area=4^2
Therefore, Area=16 cm

What is Distribute in math?
To "distribute" anything is to divide it up or to give someone a piece of it.
What does the mathematical distributive property mean then?
The distributive property is the distributive law of multiplication over operations in fundamental arithmetic, such as addition and subtraction.
Distributive property: What Is It?
This property states that multiplying the total of two or more addends by a number will provide the same outcome as multiplying each addend by the number separately and then adding the results together.
In other words, an expression of the type A (B + C) can be resolved as A (B + C) = AB + AC in accordance with the distributive property.
This characteristic also holds for subtraction.
A(B-C) = AB-AC
This demonstrates that the other two operands share operand A.

please help with question 20! thank you. it’s similar to a previous question i asked but i’m still not too sure how to approach it. thank you.
Answer:
118
Step-by-step explanation:
The key piece of information to focus on is that there are around 120 fruits. 15 is the biggest of the given divisors, and the gaps between multiples of 15 is the greatest (compared to 4 and 6) which will narrow down our options. Therefore we can first try approaching the problem by finding multiples of 15 that are close to 120.
The question says that when the number (let's call it A) is divided by 15, it leaves 13. Therefore we can express A as such:
A-13 = 15x OR 15x + 13 = A
Where 'x' represents a whole number showing that the number is divisible by 15.
The closest multiples of 15 to 120 are 105 (15*7), 120 (15*8), and 135 (15*9).
A is one of these numbers + 13, let's see which ones are closest:
105+13 = 118, 120+13 = 133, 135+13 = 148
118 is very close to 120, so let's check it with the other numbers:
118/4 = 29 r 2
118/6 = 19 r 4
The exact number of fruits is 118.
Hope this helped!
Answer:
118
Step-by-step explanation:
We are told that there are about 120 fruits.
Fruits divided equally among 4 students
Multiples of 4: 4, 8, 12, ... 112, 116, 120, 124, ...
Therefore, 116, 120 and 124 are closest to 120.
Add the given remainder of 2 to these numbers:
116 + 2 = 118120 + 2 = 122124 + 2 = 126Fruits divided equally among 6 students
Multiples of 6: 6, 12, 18, ... 108, 114, 120, 126 ...
Therefore, 114, 120 and 126 are closest to 120.
Add the given remainder of 4 to these numbers:
114 + 4 = 118120 + 4 = 124126 + 4 = 130Fruits divided equally among 15 students
Multiples of 15: 15, 30, 45, ... 105, 120, 135, ...
Therefore, 105, 120 and 135 are closest to 120.
Add the given remainder of 13 to these numbers:
105 + 13 = 118120 + 13 = 133135 + 13 = 148Therefore, as the total of 118 fruits is common to all three groups the exact number of fruits is 118.
Check
Divide 118 by each group of students:
118 ÷ 4 = 29 r 2118 ÷ 6 = 19 r 4118 ÷ 15 = 7 r 13As the remainders concur with the given amount of fruit left over for each group of students, this verifies that the exact number of fruits is 118.

Find the dimensions of an American football field. The length is 200ft. more than the width, and the perimeter is 1,040ft. Find the length and width. Use the perimeter formula P=2L+2W
The width and length of the field are 160ft and 200ft respectively
When both the given variables are related to each other, we are required to consider one variable as x and the other as a function of x to solve accordingly
Let the width of the football field be 'x' ft.
then according to given data,
length= 200 ft more than width= (x+200)ft
According to given,
Perimeter of the given field =2L+2W=1040
where L is length and W is the width
Now putting the values of length and width earlier derived, we get:
2(x)+2(x+200) =1040
2x+2x+400=1040
4x+400=1040
4x=1040-400
4x=640
x=160ft
Now, the width of the field= x=160ft
length of the field= x+200=160+200=360ft
Hence the length and the width of the field are 160ft and 360ft

Scatter plot for the positive correlationScatter plot for negative correlationScatter plot for null correlationA weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

The annual interest rate is 6.69% for 3 years at compound interest.
What does the term "compound interest" mean?
The interest you earn on interest is known as compound interest. Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You will wind up with $110.25 at the conclusion of the second year.[tex]A = P.( 1 + \frac{r}{n} )^{n.t}[/tex]
p = 5600
t = 3
I = 1200
n = 1
The interest earned I is
I = [tex]P. ( 1 + \frac{r}{n} )^{n.t} - P[/tex]
1200 = [tex]5600 . ( 1 + \frac{r}{1} )^{1.3} - 5600[/tex]
[tex]1200 = 5600 .( 1 + r )^{3} - 5600[/tex]
[tex]\frac{1200}{5600} = ( 1 + r)^{3} - 1[/tex]
[tex]\frac{3}{14} = ( 1 + r )^{3} - 1\\[/tex]
[tex]\frac{17}{14} = ( 1 + r)^{3}[/tex]
Take the log base 10 of both sides
log17 - log14 = 3.log( 1 + r)
1.23045 - 1.14613 = 3.log( 1 + r)
3.log( 1 + r) = 0.084322
log( 1 + r) = 0.028107
1 + r = [tex]10^{0.28107}[/tex]

Define the concept of an angle and show how it should be indicated in Math (notation). Mention at least two ways.
An angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.
An angle is denoted by the angle symbol ∠ which is then being followed by three letters that will represent the points that form an angle.
Lets say for example, the expression ∠ABC will mean that “the angle is formed by the points A, B and C”
where the vertex of the angle is at the point B as it is in the middle.
Angles can also be of different types like:
An Acute Angle which means an angle is less than 90 degrees.
A Right Angle which means an angle which is exactly 90 degrees.
An Obtuse Angle which is an angle more than 90 degrees and less than 180 degrees.
A Straight Angle which is an angle that is exactly 180 degrees.
And a Reflex Angle which is an angle greater than 180 degrees and less than 360 degrees.
