5 1/8 - 2 5/6
ANSWER ASAPPPP TO BE BRAINLIEST
EXPLAIN HOW AND BE RIGHT
Answer:
5 1/8 - 2 5/6
Step-by-step explanation:
Answer: 2 7 /24
Answer:
2 7/24
Step-by-step explanation:
let’s go ahead and make these fractions have the same denominator.
1/8 and 5/6
what multiple do they share?
8 * 3 = 24
6 * 4 = 24
we will change their denominators to 24.
Now to change the numerator you have to multiply it by what you multiplied the denominator by:
1/8 * 3/3 = 3/24
5/6 * 4/4 = 20/24
now we will add the whole numbers to the fraction:
5/1 * 24/24 = 120/24
2/1 * 24/24 = 48/24
now add these to the correct fraction:
120/24 + 3/24 = 123/24
48/24 + 20/24 = 68/24
Now subtract!
123/24 -68/24 = 55/24
Simplify:
55/24 = 2 7/24
Devin volunteers at Big Pup Rescue. He is mixing up shampoo solution for the dog washing station. He needs 2 cups of shampoo concentrate for every 9 cups of water. Devin will use 36 cups of water.
How much shampoo concentrate should Devin add to the water to make the shampoo solution?
cups of shampoo concentrate
Answer:
8 Shampoo Concentrate
Step-by-step explanation:
There's a ratio of 9:2 so for every 9 cups of water there's two cups of shampoo concrete.
We'll need 9 multiplied by 4 is 36
so we need to multiply 2 with 4
4 multiplied by 2 is 8

3x - 7 = 29
What is x
Answer:
x = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
3x - 7 = 29
Step 2: Solve for x
Add 7 on both sides: 3x = 36Divide 3 on both sides: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: 3(12) - 7 = 29Multiply: 36 - 7 = 29Subtract: 29 = 29Here we see that 29 does indeed equal 29.
∴ x = 12 is a solution of the equation.

Tell a folk story about the history of irrational numbers. Research what is known about irrational numbers, their development, and why they are important.
Answer:
The history of irrational numbers, The discovery of irrational numbers is usually attributed to Pythagoras, more specifically to the Pythagorean Hippasus of Metapontum, who produced a (most likely geometrical) proof of the irrationality of the square root of 2. The story goes that Hippasus discovered irrational numbers when trying to represent the square root of 2 as a fraction. However Pythagoras believed in the absoluteness of numbers, and could not accept the existence of irrational numbers. He could not disprove their existence through logic, but his beliefs would not accept the existence of irrational numbers and so he sentenced Hippasus to death by drowning. Irrational numbers are important because without it we wouldn't have the continuum of real numbers which would make geometry impossible to do in life.

Write the equation in point-slope form of the line that passes through the given points. Then write the equation in slope-intercept form.
(-6,6),(3,3)
Answer:
point-slope form: [tex]y-3=-\frac{1}{3}(x - 3)[/tex]
slope-intercept form: [tex]y=-\frac{1}{3}x+4[/tex]
Step-by-step explanation:
point-slope form is: y - y1 = m(x - x1)
slope-intercept form is: y = mx + b
The formula used to find the slope(m): [tex]\frac{y2-y1}{x2-x1}[/tex]
(x1, y1) = (3, 3)
(x2, y2) = (-6, 6)
The first thing we need to do to write the equations is to find the slope. We can do this by inputting the given points into the slope formula:
[tex]\frac{6-3}{-6-3}[/tex]
Simplify:
6 - 3 = 3
-6 - 3 = -9
[tex]\frac{3}{-9} =-\frac{1}{3}[/tex]
The slope is [tex]-\frac{1}{3}[/tex]. We can now write the equation in point-slope form:
[tex]y-3=-\frac{1}{3}(x - 3)[/tex]
To write the equation in slope-intercept form, we need to find the value of b. To find its value, input the value of the slope and one point into the equation for slope-intercept form:
y = mx + b
3 = [tex]-\frac{1}{3}[/tex](3) + b
Now you can solve for b:
3 = [tex]-\frac{1}{3}[/tex](3) + b
3 = -1 + b
4 = b
Now that we know the value of b, we can write the equation in slope-intercept form:
[tex]y=-\frac{1}{3}x+4[/tex]
I hope this helps. :)
Equation in point-slope form of the line that passes through the given points (-6,6) and (3,3) is y=-1/3x+4.
What is slope of line?The slope of the line is the ratio of the rise to the run, or rise divided by the run.
The given two points are (-6,6) and (3,3)
x1=-6, y1=6, y1=3 and y2=3
m=y2-y1/x2-xq
m=3-6/3-(-6)
m=-3/9
m=-1/3
Hence slope of line is m=-1/3
To write the equation in slope-intercept form, we need to find the value of b. To find its value, input the value of the slope and one point into the equation for slope-intercept form:
y = mx + b
3=-1/3(3)+b
4=b
Now that we know the value of b, we can write the equation in slope-intercept form:
y=-1/3x+4
Hence equation in point-slope form of the line that passes through the given points (-6,6) and (3,3) is y=-1/3x+4.

Answer:
-0.0936538462
Step-by-step explanation:
Start by solving the right side of the equation
1 - 2.87 = -1.87
now we have:
3 + 5.2c = -1.87
subtract 3 from both sides to get:
5.2c = -4.87
divide both sides by 5.2 to get:

Given:
w = 0.75f
Where,
w = number of cups of water
f = number of cups of flour
Find w when f = 4 cups
w = 0.75f
Substitute f = 4 into the equation
= 0.75(4)
= 3
w = 3 cups when f = 4 cups

You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year.
The initial heights are shown.
Write a system of linear equations that represents this situation.
Answer:
[tex]s(x) = 8 + 4x[/tex]
[tex]h(x) = 14 + 6x[/tex]
Step-by-step explanation:
Given
Spruce Tree (s):
[tex]Initial\ Height = 8[/tex]
[tex]Growth = 4[/tex] (yearly)
Hemlock Tree (h):
[tex]Initial\ Height = 14[/tex]

Represent as system of linear equations
Let the number of years be x.
In both cases, the equation can be formed using:
[tex]Equation = Initial\ Height + Growth * x[/tex]
For Spruce Tree (s):
[tex]s(x) = 8 + 4 * x[/tex]
[tex]s(x) = 8 + 4x[/tex]
For Hemlock Tree (h):
[tex]h(x) = 14 + 6 * x[/tex]
