Answer:
I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.
Step-by-step explanation:
Since 3/4 is a fraction, all fractions can be converted into decimals.
3/4 is also known as 75%, which can be simplified into 0.75 in decimal terms.
Now that you know that 3/4 can be simplified to 0.75, you now need to take that 0.75, and multiply it by 16. You can use a calculator to do this, or you could work it out on a sheet of paper.
An easy way to do this, is to know that 25%, (0.25) of 16 is 4. This is because 4 times 4 is 16. Knowing this, if you are looking for 75% of 16, (0.75) you can multiply 4 by 3, knowing that it is 75% of 16.
The answer to that is 12.
3 x 16 = 48 and if you take 48 and divide it by 4, you will get 12.
You can explain this by writing; I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.

7. © MP.6 Be Precise Alyssa made a pink
and white striped blanket for her bed.
There are 7 pink stripes and 6 white
stripes. Each stripe is 8 inches wide.
How wide is Alyssa's blanket? Explain.
Answer:
104 Inches
Step-by-step explanation:
Alyssa's blanket contains 7 pink stripes and 6 white stripes.
Total Number of Stripes =7+6=13
Since each stripe is 8 inches wide.
The width of Alyssa's blanket will be the product of the number of stripes by the width of each stripe.

solve the equation x² + 6x + 1 = 0
Answer:
Two solutions were found :
x =(6-√40)/2=3-√ 10 = -0.162
x =(6+√40)/2=3+√ 10 = 6.162
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring x2-6x-1
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is -6 .
-1 + 1 = 0
The solutions to the equation x² + 6x + 1 = 0 are -0.177 and -5.823.
Given:
quadratic equation x² + 6x + 1 = 0
The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the following formula:
[tex]x = \dfrac{-b \pm \sqrt {(b^2 - 4ac)}}{2a}[/tex]
In our equation, a = 1, b = 6, and c = 1.
Now, let's plug these values into the quadratic formula:
[tex]x = \dfrac{-6 \pm \sqrt {(6^2 - 4(1)(1))}}{2(1)}[/tex]
x = (-6 ± √(36 - 4)) / 2
x = (-6 ± √32) / 2
Now, the two solutions for x:
1. x = (-6 + √32) / 2
= (-6 + 5.66) / 2
= -0.177
2. x = (-6 - √32) / 2
= (-6 - 5.66) / 2
-5.823
So, the solutions are -0.177 and -5.823.

what is −5x+4y=3
x=2y−15
Answer:
x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5(2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = -72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2(12) - 15
x = 24 - 15
x = 9
Answer:
x = 9

The area of a square plot of land is 325 square meters. What is the perimeter of the square, in meters? Express your answer in simplest radical form.
Hey there! I'm happy to help!
The first thing to do is find the square root of the area so we know what one of the sides are. Since our answer is supposed to have a radical, we don't need to simplify the radical.
So, each side is just √325.
Now, we multiply this by four to find the perimeter.
4√325
However, we can simplify that. To do this, we will find all of the prime factors of 325. If there are two of a certain number, we will take that number and pull it to the outside of the radical and cancel out both of the numbers inside the radical. So, if you had two 2's inside the radical, you would cancel them out and put a single two on the outside.
4√5×5×13
We can put the five outside
4×5√13
The perimeter is 20√13.
I hope that this helps! Have a wonderful day!

greater x=
Answer:
In conclusion,
lesser x =−1
greater =9
Step-by-step explanation:
The zeros of the function f(x) = (x - 4)² - 25 are -1 and 9, and the solutions from least to greatest are -1, 9.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the function's zeros, we need to solve for f(x) = 0.
We can simplify the given function as:
f(x) = (x - 4)² - 25
= (x - 4 + 5) (x - 4 - 5)
= (x + 1)(x - 9)
Now, we can set each factor equal to zero to find the zeros of the function:
x + 1 = 0 or x - 9 = 0
Solving for x in each equation, we get:
x = -1 or x = 9
Therefore,
The zeros of the function f(x) = (x - 4)² - 25 are -1 and 9, and the solutions from least to greatest are -1, 9.

The cost of 6 sandwiches and 4 drink is $53. The cost of 4 sandwiches and 6 drinks is $47. How much does one sandwich cost?
Answer:
sandwich = 6.50

Step-by-step explanation:
(3x + 2y =19)(3)
-9x + 8y =-29
9x + 6y = 57 NOTE: we cross here 9x in first
-9x + 8y = -29 we cross here - 9x in second
Since 9x and - 9x are opposite
___________
6y +8y = 57 - 29
14y = 28
Y=28/14
Y=2
Replace y in second equation of this system:
-9x + 8y = - 29
-9x +8(2)= - 29
-9x + 16 = - 29
