Step-by-step explanation:
8(b ÷ 2) - (c + 4)
(Putting values of b = 1/2 and c = 1/4)
[tex] = 8( \frac{1}{2} \div 2) - ( \frac{1}{4} + 4)[/tex]
[tex] = 8( \frac{1}{2} \times \frac{1}{2} ) - ( \frac{1 + 16}{4} )[/tex]
[tex] = 8 \times \frac{1}{4} - \frac{17}{4} [/tex]
[tex] = 2 - \frac{17}{4} [/tex]
[tex] = \frac{8 - 17}{4} [/tex]
[tex] = - \frac{9}{4} (ans)[/tex]
Answer:
It is A). -9/4
Step-by-step explanation:
[tex]8(b \div 2) - (c + 4)[/tex]
when b is ½ and c is ¼ :
[tex] = 8( \frac{1}{2} \div 2) - ( \frac{1}{4} + 4) \\ \\ = 8( \frac{1}{4} ) - ( \frac{17}{4} )[/tex]
open brackets:
[tex] = \frac{8}{4} - \frac{17}{4} [/tex]
from LCM formular:
[tex] = \frac{8 - 17}{4} \\ \\ = \frac{ - 9}{4} [/tex]

Which of the following represents "the difference between a number and eight is twenty-two"?
N - 8 = 22
8 - 22N
8 - N = 22
Answer:
N - 8 = 22
Step-by-step explanation:
The variable N goes first. If you look at the question over again, it says the difference between a number and 8 is 22. The number uses the variable N if your trying to figure out what it is, so your gonna subtract your number from 8 to get 22

Check out the diagram below.
U is between T and V, and U is on segment TV. We can see that the smaller pieces TU and UV add back up to the largest segment TV
TU + UV = TV
17 + 18 = TV
35 = TV

I'll do part (a) to get you started.
The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.
We also see that b = 123 as well since a = b (they are vertical angles).
Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.
c+123 = 180
c = 180-123
c = 57
-------------------------
To summarize, we have these three angles
a = 123
b = 123
c = 57
Answer:
a) a=57° b=123° c=123°
b) f=98° d=98° e=98°
c) g=75° h=75°
Step-by-step explanation:
a) a°+123°=180° (angle on a straight line=180°)
a°=180°-123°
a°=57°
b°=123° (alternative angles)
c=123° (vertically opposite angles are equal)
b)f+82°=180° (angle on a straight line=180°)
f=180°-82°
f=98°
f=d (corresponding angles are equal)
d=e (vertically opposite angles are equal)
c) h=75° (corresponding angles are equal)
g=h (vertically opposite angles are equal)

If ∠MOK and ∠JOM are supplementary angles, then what is the value of x and m∠LOK?
A.
x = 130; m∠LOK = 66°
B.
x = 50; m∠LOK = 114°
C.
x = 114; m∠LOK = 50°
D.
x = 66; m∠LOK = 130°
Answer:
B. x = 50; m∠LOK = 114°
Step-by-step explanation:
Supplementary angles add to 180
∠MOK + ∠JOM=180
66+ ∠JOM=180
<JOM = <LOK since they are vertical angles
<LOK = x+64
66+ x+64=180
Combine like terms
130+x = 180
x = 180-130
x = 50
<LOK = x+64 = 50+64 = 114

Additional comment
The denominator on the left is x. The least common denominator on the right is 6. To clear fractions, you can multiply by the product of these values: 6x. Doing this gave us the one-step linear equation 6 = 3x.
As with any operation performed on an equation, the operation must be performed on both sides of the equation. Here, we multiply both sides by 6x. It is a bit unconventional and confusing to show that multiplication as you have shown it in your figure. Usually, it would be shown as in the 2nd line of the solution, above.

Hey there! I'm happy to help!
First of all, don't worry so much about struggling with something difficult! It's part of the human experience. Our minds are wired to be challenged but then when we push through and have faith in ourselves that's how we grow and improve!
What we are dealing with here are lines. We are being given the coordinates for one endpoint of a line and a midpoint and we want to find the other endpoint.
Let's just go one-dimensional first to make this easier to understand. Imagine that you have a number line. You draw a line going from 1 to 7. So, 1 and 7 are the two endpoints. Your midpoint is going to be halfway between those two. To find the middle of anything, you just add the two numbers and divide them by two.
1+7=8
8/2=4
So, 4 is our midpoint in this situation.
So, what if we just had our endpoint 1 and our midpoint 4? Well, we see that we go forward three spaces to get to 4. Now we are halfway! Then, we just do another three to make it to our finish line, which is 7. Or, we just take that distance and multiply it by two! This is related to our divide by two rule but just backward!
So, let's look at these problems.
------------------------------------------------------------------------------------------
A.
We have the coordinates of our line here. Our endpoint is (1,-9) and our midpoint is (4,-1). Remember what we did with our number line? We are basically going to do it with our x and y values.
So, to go from our endpoint 1 to 4 we go three spaces. If we go another 3 spaces, it will be 7. So, our x-value is 7.
With our y-values, we go from -9 to -1, so we climb 8 spaces. If we add another 8 spaces we will end up at 7, so our y-value is 7 again!
So, our other endpoint is (7,7)!
------------------------------------------------------------------------------------------
B.
To go from -2 to 9 is adding 11, so we add another 11 to 9 to give us an x-value of 20.
Going from 19 to 2 is subtracting 17, so we need to subtract another 17, which gives us a y-value of -15.
So, our endpoint is going to be (20, -15).
------------------------------------------------------------------------------------------
Have a wonderful day and keep on learning! :D
