It’s not 51 btw there’s a space

Answers

4.875because 5 1/8 = 41/8 - 1/4 = 4.875
K=4.875 or 4 7/8. First you use the inverse property and do 5 1/8 -1/4= 4.875.
The inverse property is just using the opposite sign like addition with subtraction and multiplication with division. You would use the opposite sign in this case the total.

I need help -x + 5y = 14, x + 3y = 18 solve by substitution

Answers

Answer:

x=6,y=4 equation form

or

(6,4) point form

Step-by-step explanation:

Answer: x = 6, y = 4

Step-by-Step Explanation:

=> -x + 5y = 14 (Eq. 1)
=> x + 3y = 18 (Eq. 2)

From Eq. 2,
=> x = 18 - 3y (Eq. 3)

Substitute value of ‘x’ from Eq. 3 in 1 :-

-x + 5y = 14
-(18 - 3y) + 5y = 14
-18 + 3y + 5y = 14
8y = 14 + 18 = 32
=> y = 32/8 = 4

Therefore, y = 4

Substitute value of ‘y’ in Eq. 3 :-

x = 18 - 3y
x = 18 - 3(4)
x = 18 - 12
=> x = 6

Therefore, x = 6

Answer: 155in2

Step-By-Step explanation:

To find the area we had to split up the shape into parts. We also know that the formula for Area is Length x With . We split of the shape into 3 parts we will call them 1, 2, and 3
1: Area= L x W
1: Area = 7 x 6
1: Area = 42

2: Area= L x W
2: Area = 5 x (13+4)
2: Area = 85


3: Area= L x W
3: Area = 4 x ( 12-5)
3: Area = 28

now that we know all the areas for each shape we need to add them together.

42+85+28= 155in2

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.

Answers

Answer:

The point closest to the number 40

Step-by-step explanation:

To find volume of cone:

[tex]V=\pi r^{2} \frac{h}{3}[/tex]

(but in this case we will be substituting [tex]\pi[/tex] for it approximation: 3.14)

So our new equation is [tex]V= 3.14r^{2} \frac{h}{3}[/tex]

All right, let's get to work now.

Following the order of operations our first step would be: [tex]3^{2}[/tex] or 3x3 wich is 9Next step would be 3.14x9, which is 28.26After that we would solve [tex]\frac{4}{3}[/tex], which is 1.3 repeating but we can round to the nearest tenth and get 1.3Next we would multiply 28.26 by 1.3 which is 36.73800

We would next round to the nearest whole and our final answer is: 37

Go 7 units through x-axis, then move up 5 units along the y-axis.

Answer:

An address on a coordinate plane is made up of an x value and a y value that correspond to the x- and y-axes. This "address" is called a coordinate point, and is written in the form: (x,y). So, you would need to move 7 spaces right and 5 spaces up.

How do i write mixed numbers as an improper fraction?
Explain with examples.

Answers

Answer:

A mixed fraction can be written as an improper fraction by multiplying the whole number with the fraction's denominator and adding that to the numerator, and finally writing that result on top of the denominator.

Step-by-step explanation:

Answer:

You have to multiply the whole number by the denominator and then add the answer you get with the numerator.

Step-by-step explanation:

For example, the fraction 10 [tex]\frac{1}{3}[/tex] is a mixed number right? So then you multiply 10x3=30. Then you add 30+1=31. So then the answer would be [tex]\frac{31}{3}[/tex].

Answer:

  (b)  1/3

Step-by-step explanation:

A function "zero" is a value of x that makes the value of the function be zero. It may also be called a "root" of the function. On a graph, it is an x-intercept.

The zeros are the solutions to the equation f(x) = 0. For a quadratic like the one given, there are two of them. For this function, they are distinct, so one will be larger than the other.

Graph

There are a number of ways the solutions to this equation can be found. Technology, in the form of a graphing calculator, can show you the x-intercepts easily (see attached). They are x=-2/5 and x=1/3.

Factoring

We can also factor the equation. Doing this requires that we find factors of the product (15)(-2) = -30 that have a sum equal to the coefficient of x, +1. Here are some factor pairs:

  -30 = (-1)(30) = (-2)(15) = (-3)(10) = (-5)(6)

The corresponding sums are 29, 13, 7, 1. Hence the last factor pair, {-5, 6}, is the one we need.

Rewriting the 3-term polynomial to a 4-term polynomial by splitting the middle term using these factors, we have ...

  15x² -5x +6x -2 = 0

Factoring pairs of terms gives ...

  5x(3x -1) +2(3x -1) = 0

  (5x +2)(3x -1) = 0 . . . . . . . factor out the common factor

The product of these factors can only be zero of one of them is zero. (This is the "zero product rule.") Setting the factors to zero, we find the values of x that make f(x) = 0: the zeros of the function.

  5x +2 = 0   ⇒   x = -2/5

  3x -1 = 0   ⇒   x = 1/3

The zeros of the function are -2/5 and 1/3.

The larger zero is 1/3.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. Kevin spins the spinner 180 times. Kevin determines about how many times the spinner will land on red or green, and his work is shown below.

-------------------------------------------------- x number of spins =
Total number of sections

------- (180) = 36
10

What mistake did Kevin make, if any?

A. Kevin has the formula reversed; it should be the total number of sections over
the number of red or green sections.

B. Kevin should have used a 4 in the numerator because there are 2 red sections
and 2 green sections.

C. Kevin should multiply by the number of sections in the spinner rather than the
total number of spins.

D. Kevin calculated the prediction correctly and did not make any mistakes.
