Step-by-step explanation:
1) Find the Least Common Denominator (LCD) of [tex]\frac{15}{32} ,\frac{7}{31}[/tex] In other words, find the Least Common Multiple (LCM) of 32,31.
Method 1: By Listing Multiples
1. List the multiples of each number.
Multiples of 32: 31,64,96,... 928, 960 ,992,...
Multiples of 31: 31, 62, 93 , ... , 930, 961 , 992, ...
Find the smallest number that is shared by all rows above. This is the LCM.
LCM = 992
Method 2: By Prime Factors
1. List the prime factors of each number.
Prime Factors of 32: 2,2,2,2,2
Prime Factors of 31: 31
2. Find the union of these primes.
2,2,2,2,2,31
3. Multiply these numbers: 2 * 2 * 2 * 2 * 2 * 31 = 992. This is the LCM.
LCM = 992
2) Make the denominators the same as the LCD.
[tex]-\frac{15*31}{32*31} +\frac{7*32}{31*32}[/tex]
3) Simplify. Denominators are now the same.
[tex]-\frac{465}{992} +\frac{224}{992}[/tex]
4) Join the denominators.
[tex]\frac{-465+224}{992}[/tex]
5) Simplify
[tex]-\frac{241}{992}[/tex]
Decimal Form: -0.242944

Write the following numbers in order of size. Start with the smallest number. -8 2 -12 5 10
Answer:
-12, -8, 2, 5, 10
Step-by-step explanation:
-12, -8, 2, 5, 10
Answer:
-12, -8, 2, 5, 10
Step-by-step explanation:
We have to remember here that when integers are negative, the number that looks the biggest is actually the smallest! What do I mean? Well, a value of -100 is actually way smaller than a value of -1, since it's a lot farther to the left of 0 than -1 is. Does that make sense?
Let's take that in mind as we start looking at our values. If what I just said is true, -12 is the smallest value, since it's the farthest to the left of 0. Then comes -8. From there, it's not too hard. 2 is the next smallest, then 5, and finally, 10 is our greatest number.
So, our answer is -12, -8, 2, 5, 10. Hopefully that's helpful! :)

Find the slope of the table.
Answer:
Slope= -4
Step-by-step explanation:
Slope is rise over run (y over x)
So, looking at the table, you can see that every time the y values went down by 8, the x values went up by 2.
So, the slope can be written as:
-8/2
Simplified to -4/1 or just -4

if you subtract 15 from a number and multiply by-6, the result is -54. What is the number?
Answer:
24
Step-by-step explanation:
You do the opposite of whats states -54 divided by -6 because it says the number was multiplied which gives us 9 then since 15 was subtracted we instead add 15 which equals 24.
Answer:
the number is -5.7
Step-by-step explanation:
do everything in reverse operations,
-54 divided by -6= 9.3
9.3-15= -5.7
For proof you can do it yourself on a calculator.

Answer:
x=52º
Step-by-step explanation:
A triangle's angles are equal to 180º.
Given the opposite angle to H is 66º, we can find the opposite angle of angle I. The opposite angle of angle K is 62º, assuming that it is equivalent to the opposite angle of angle I we can solve for x.
66+62+x=180
Add 66 and 62.
128+x=180
Subtract 128 from both sides of the equation.
x=52
Angle x is equal to 52º.

What is the equation of the line that passes through the point (-6,-2)and has a slope of 1/6
Answer:
y = 1/6x -1
Step-by-step explanation:
Use point-slope form: y - y₁ = m (x - x₁)
y - (-2) = 1/6 (x - (-6))
y + 2 = 1/6x + 1
y = 1/6x - 1
Answer:
[tex]y=\frac{1}{6}x-1[/tex]
Step-by-step explanation:
According to,
y = mx + c
They have already given the slope of the line.
That means they've given value for m
So,
m = [tex]\frac{1}{6}[/tex]
And now we have to find the value of c ( the intercept on the y axis) using (-6,-2)
Here,
( -6 , -2 )
↑ ↑
( x , y )
Let us find the c now.
y = mx + c
[tex]-2 =\frac{1}{6} *-6+c\\-2=\frac{-6}{6} +c\\-2=-1+c\\-2+1=c\\-1=c[/tex]
Now let's write the equation of the line like this
y = mx+ c
[tex]y=\frac{1}{6}x-1[/tex]
Hope this helps you.

Plz help me solve for x and y
Answer:
x = 40°
y = 30°
Step-by-step explanation:
Given parallelogram ABCD :
∠A = 3x°∠B = 2y°∠C = 120°∠A = ∠C∠B = ∠D∠A + ∠B = 180°∠B + ∠C = 180°∠A + ∠B + ∠C + ∠D = 360°∠A = ∠C
3x = 120
x = 120 ÷ 3
x = 40°∠B + ∠C = 180°
2y + 120 = 180
2y = 180 - 120
2y = 60
y = 60 ÷ 2
y = 30°Answer:
x = 40°
y = 30°
Step-by-step explanation:
Given the diagram of a parallelogram, where:
∠A = 3x°, ∠B = 2y°, and ∠C = 120°
The given problem also requires us to find the values of x and y.
In reference to the Parallelogram Opposite Angles Theorem, where it states that: if a quadrilateral is a parallelogram, then it will have congruent opposite angles. In other words, ∠A ≅ ∠C , and ∠B ≅ ∠D.
Solve for x:Hence, we can establish the following equality statement to solve for the value of x:
m∠A = m∠C
3x° = 120°
Divide both sides by 3 to solve for x:
[tex]\displaystyle\mathsf{\frac{3x^{\circ}}{3}=\:\frac{120^{\circ}}{3}}[/tex]
x = 40°
Therefore, the value of x = 40°.
Solve for y:In order to solve for y, we must refer to the Parallelogram Consecutive Angles Theorem, where it states that if a quadrilateral is a parallelogram, then its consecutive angles are supplementary whose sum add up to 180°.
In the given diagram, ∠A and ∠D, ∠B and ∠C are consecutive angles.
We can establish the following equation to solve for the value of y:
m∠B + m∠C = 180°
2y° + 120° = 180°
Subtract 120° from both sides:
2y° + 120° - 120° = 180° - 120°
2y° = 60°
Divide both sides by 2 to solve for y:
[tex]\displaystyle\mathsf{\frac{2y^{\circ}}{2}=\:\frac{60^{\circ}}{2}}[/tex]
y = 30°
Therefore, the value of y = 30°.
how to find the vertex of a parabola in standard form
Step-by-step explanation:
TO find the vertex, you need to find the x− and y− coordinates.
The formula for the axis of symmetry and the x-coordinate of the vertex is:
x = -b over 2a
To find the y-coordinate the vertex, substitute the value for x into the equation and solve for y
y=a(-b over 2a) squared + b(-b over 2a) + c
Dillon earned $170 working 20 hours at the carwash what was his hourly rate of pay?
To find this answer, we must divide the amount Dillion earned, by the time he put into his work.
170 / 20 = 8.5
Therefor, we now know that Dillion makes $8.5 an hour.
Help me with this please
Answer:
5
Step-by-step explanation:
By process of elimination, we can say for sure that C and D are not the right answers because as x- the numbers on the top- increases, y- the numbers on the bottom- increases. This means that the slope is not negative, because the slope is the rate of change and it does not have a negative rate of change.
The equation for slope is y2-y1 / x2-x1. Meaning, y is on top and x is on bottom. This creates a fraction. So let's take 0 and 1 for X, the first and second values, and 3 and 8 for y, the first and second values. We swap them, because the second y value comes first, so we have 8 - 3 for the top, the numerator. Then we have 1 - 0 for the bottom, the denominator. Solving 8 - 3 and 1 - 0, we have 5/1. 5/1 simplifies to 5, and thus 5 is your slope.
