Answer:
Here's how to subtract 3/8 from 8/12:
8
12
−
3
8
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 8 by 8, and get 64.
Then we multiply 3 by 12, and get 36.
Next we give both terms new denominators -- 12 × 8 = 96.
So now our fractions look like this:
64
96
−
36
96
Step 2
Since our denominators match, we can subtract the numerators.
64 − 36 = 28
So the answer is:
28
96
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
28
96
÷ 2 =
14
48
Let's try dividing by 2 again...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
14
48
÷ 2 =
7
24
Let's try dividing by 2 again...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 7. So we're done reducing.
There you have it! The final answer is: 0.29166666666

Answer:
I don't see anything
Step-by-step explanation:
solve for c
solve for r
Answer:
Step-by-step explanation:
9(c+7)=27
9c+63=27 subtract 63 from both sides
9c= -36 divide by 9
c= -4
3(2r-8)+4r=76 foil
6r-24+4r=76 combine like terms
10r-24=76 add 24 to both sides
10r+100 divide by 10
r= 10

1. slope = 0
2. slope = -5
3. slope = 5
4. slope = 0
5. slope= -1
6. slope = -1/2
7. slope = 3
8. slope = -1/10
9. slope = 1/2
10. slope = -1/2
Explanation :
I won't explain every question because that'll take forever but I can explain one step by step.
An example is number 5
You have the points, ( -4 , 5 ) ( 1 , 0 )
You need to use the SLOPE FORMULA
So first put an x1 and y1 below the points -4 and 5.
then put x2 and y2 below the points 1 and 0
the slope formula is m = y2-y1/x2-x1
plug in the numbers which will look like
0-5/1+4
It's plus 4 instead of -4 because a negative and negatives gives you a postivie
Simplify and you get m = -1
what is the slope for (-11, 1) and (-2, 6)?
Answer:
5/9
Step-by-step explanation:
You can verify me by using the y2-y1/x2-x1 formula

➤ How to solve ?
⠀⠀⠀⠀
That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
SolutiOn :
➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3
➠ 7x + 31 = 8x - 27x - 3 - 3
Now, we will bring the variable on left hand side and constants on right hand side
➠ 7x - 8x + 27x = - 31 - 3 - 3
➠ 26x = -37
➠ x = -37/ 26
➠ x = - 1.42
∴ The value of x is -1.42 .

2x - 3y = 6
Find the x and y Intercepts
Answer:
x-intercept(s): (3,0)
y-intercept(s): (0,−2)
Step-by-step explanation:
Answer:
x=3 and y=-2
Step-by-step explanation:
2x - 3y = 6
cancel out the y
2x - 3(0) = 6
2x = 6
divide both sides by 2
x = 3
2x - 3y = 6
cancel out the x
2(0) - 3y = 6
-3y = 6
divide both sides by -3
y = -2
Hope this helps!!
Solve the system of equations by substitution. y = 2x y = x +1
Step-by-step explanation:
y = 2x
y = x + 1
y-1 = x
y = 2x
y = 2 (y - 1)
y = 2y - 1
y = -1

the opposite of 5x and 5x+8?
the opposite or addictive increase of 5x is -5x.
the opposite or addictive increase of 5x + 8 is -5x -8.
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x5+85 f - 1 ( x ) = x 5 + 8 5 is the inverse of f(x)=5x−8 f ( x ) = 5 x - 8 .
In the figure above, rectangle V'W'X'Y' is a dilation of rectangle VWXY. What is the scale factor of the dilation?
A. 0.25
B. 2
C. 3/4
D. 1/4
Answer:
D. [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Rectangle VWXY after dilation, became compressed to rectangle V'W'X'Y'.
This makes both rectangles similar. It follows that the corresponding side lengths or segments of both figure would be proportional. Thus, the scale factor of the dilation would be:
[tex] \frac{W'X'}{WX} [/tex]
W'X' = 5
WX = 20
Plug in the values
[tex] \frac{5}{20} [/tex]
Simplify
[tex] scale factor = \frac{1}{4} [/tex]

Answer:
∠x = 30°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the arc it subtends. Angle BAC is half the measure of arc BC.
Arc ABC is a semicircle, so measures 180°. Of that, arc AB is 120°, so the remainder, 180° -120° = 60° is the measure of arc AB.
Angle x is half that, or 60°/2 = 30°.
The measure of angle x is 30°.

The price of a particular stock is represented by the linear equation y = negative 0.91 x + 103.47, where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars. If this relationship continues, what is the price of the stock after it has been owned for 12 weeks?
$92.55
$94.37
$100.52
$114.39
Answer:
$92.55
Step-by-step explanation:
Substitute the value of x, which is in weeks, to 12.
so y = 0.91(12) + 103.47
y = 92.55

Step-by-step explanation:
Given set is:
{red, blue, pink, green}
First of all, we have to calculate the number of subsets
In the given set,
n = 4
So the number of subsets will be: 2^4 = 16
The subsets are:
{} , {red}, {blue}, {pink}, {green} , {red, blue}, {red, pink}, {red, green}, {blue, pink} , {blue, green} , {pink, green}, {red, blue, pink}, {red, pink, green}, {blue, pink, green}, {red, blue, green}, {red, blue, pink, green}
