The question states that we are looking for the reciprocal of 8/19.
Recall what a reciprocal is. A reciprocal, when looking at a number, is what is multiplied with it for it to equal 0. It is commonly regarded as just the fraction flipped. (For example, the reciprocal of 1/2 would be 2, or 2/1. 2 * 1/2 = 1)
But why does flipping a fraction work?This goes back to the simplifying, when multiplying two fractions together.
If you were to multiply two fractions, say [tex]\frac{5}{4}[/tex] and [tex] \frac{4}{5}[/tex], you could look at the numerator of one and the denominator of another, and cancel them out. In this case, the numerator of one is 5, and the other is also 5. Cancelling those out makes both one. If you cancel out 4 and 4 too, you get 1/1 * 1/1, or just 1.
We could go on asking why these methods work forever. Why does cancelling out a numerator and a denominator of separate fractions work? (A simple explanation is when the separate fractions are multiplied together, you could divide both sides by the factor which was originally used to cancel out with, which is what was stated above but simpler.)
Now, we can figure out the answer.Since we know the reciprocal is just the flipped form of the fraction, we can simply flip 8/19 to get our answer.
8/19 flipped is 19/8, which is our answer.
Hope this helped!What is the slope and y-intercept of the equation 3(y − 2) + 6(x + 1) − 2 = 0? A. slope = -2, y-intercept = B. slope = 2, y-intercept = C. slope = -2, y-intercept = D. slope = 2, y-intercept = E. slope = -2, y-intercept =
The correct answer is that the slope is equal to -2 and the y-intercept is equal to 2/3.
To find this, follow the order of operations and solve for y.
3(y − 2) + 6(x + 1) − 2 = 0 ----> distribute
3y - 6 + 6x + 6 - 2 = 0 -----> combine like terms
3y + 6x - 2 = 0 -----> subtract 6x
3y - 2 = -6x -----> add 2
3y = -6x + 2 -----> divide by 3
y = -2x + 2/3
Now we can find the slope as the coefficient of x (-2) and the intercept as the constant (2/3)
Answer: The slope of the given line is -2 and y-intercept is [tex]\dfrac{2}{3}.[/tex]
Step-by-step explanation: We are given to find the slope and y-intercept of the following equation of a line:
[tex]3(y-2)+6(x+1)-2=0~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
the slope-intercept form of the equation of a line is given by
[tex]y=mx+c,[/tex] where m is the slope and c is the y-intercept of the line.
From equation (i), we have
[tex]3(y-2)+6(x+1)-2=0\\\\\Rightarrow 3y-6+6x+6-2=0\\\\\Rightarrow 3y+6x=2\\\\\Rightarrow 3y=-6x+2\\\\\Rightarrow y=-2+\dfrac{2}{3}.[/tex]
Thus, the slope of the given line is -2 and y-intercept is [tex]\dfrac{2}{3}.[/tex]

Mrs. Santos has 24 students in her class. Five-eighths of her students have nicknames. Mr. Russo also has 24 students in his class. Only one-third of his students have nicknames. How many students from Mrs. Santos' class and Mr. Russo's class do not have nicknames?
In Mrs. Santos' class, five-eighths of the students have nicknames, meaning that three-eighths don't have nicknames. Three-eighths of 24 is 9, so 9 students don't have nicknames.
In Mr. Russo's class, one-third of the students have nicknames, meaning that two-thirds don't have nicknames. Two-thirds of 24 is 16, so 16 students don't have nicknames.
Therefore, there are 9 students from Mrs. Santos' class and 16 students from Mr. Russo's class who don't have nicknames.
convert 6/9 into a fraction with d
enominator of 27
To convert the fraction 6/9 to a fraction with a denominator of 27, multiply both the numerator and denominator by 3. The resulting fraction is 18/27.
Explanation:To convert the fraction 6/9 into a fraction with a denominator of 27, first identify the multiplication factor that changes 9 into 27. In this case, it's 3 (because 9*3 = 27). You need to maintain the fraction equivalent by applying the same operation to the numerator. So, multiply 6 by 3 to get 18. Therefore, the equivalent fraction of 6/9 with a denominator of 27 is 18/27.

65834 rounded to the nearest ten thousand
Answer:
70,000
Step-by-step explanation:
65834
First, identify the ten-thousands digit.
4 - ones digit
3 - tens digit
8 - hundreds digit
5 - thousands digit
6 - ten-thousands digit.
The 6 is the ten-thousands digit.
First, make every digit to the right of the ten-thousands digit zero.
You get 60,000.
Now check the digit just to the right of the ten-thousands digit. If it is zero through 4, you are done. If it is 5 through 9, the 6 goes up 1 to 7. The digit to the right of the ten-thousands digit is 5, so the 6 goes up 1 to 7, and the answer is 70,000.

Combine Like Terms, Division Property of Equality, Addition Property of Equality, Commutative Property, Given
19 = 5x - 1
Solve for x.
Note the equal sign. What you do to one side, you do to the other. Isolate the x. Do the opposite of PEMDAS.
=> Addition Property of Equality.
Add 1 to both sides
19 = 5x - 1
19 (+1) = 5x - 1 (+1)
=> Combine like terms
Add 19 and 1
19 + 1 = 5x
20 = 5x

Divide 5 from both sides
(20)/5 = (5x)/5
x = 20/5

Find the missing angle measurements.
The options are :
60°, 64°, 45°, 49°, 53°
Answer:
Top right ?- 60
? above 64- 64
Bottom left- 45
Step-by-step explanation:
Triangles equal 180.
The question mark above 64, the 64 and ? are congruent so the question mark is 64.
The question mark in top right, add 64+56=120. Since triangles equal 180, subtract 180-120=60
The question mark in bottom left, add 64+71=135. Since triangles equal 180, subtract 180-135=45
Hope it helps!
The value of the three missing angles are 45°, 60°, and 64°.
We have,
From the figure,
we have vertical angles.
So,
One missing angle is 64°.
Now,
There are two triangles.
The sum of angles in a triangle is 180.
So,
56 + 64 + x = 180
x = 180 - 56 - 64
x = 60°
And,
The sum of angles in a triangle is 180.
So,
71 + 64 + y = 180
y = 180 - 71 - 64
y = 45°.
Thus,
The value of the three missing angles are 45°, 60°, and 64°.

TRUE
The equation 9p+8=10p+7 is a true equation as it provides a specific solution upon rearrangement and simplification which is p = 1.
Explanation:The equation you have provided: 9p + 8 = 10p + 7, is what we refer to as an equation in algebra. A way to determine if an equation is true, false or open is by attempting to solve. Firstly, let's put all 'p' terms on one side of the equation and numbers on the other. It would look like this after simplification: 10p - 9p = 8 - 7, which simplifies to: p = 1. Since we found a specific solution (p = 1), this means the equation is classified as true.

A football team lost 9 yards during a play the team had a combined gain or loss of 0 yards after the next play what interger represents the yards gained or lost on the next play ? Show this on the number line .
Answer:
The integer represents the yards gained or lost on the next play is 9.
The required number line is shown in figure 1.
Step-by-step explanation:
Consider the provided information.
A football team lost 9 yards during a play.
Represent Lost with a negative sign.
Thus, lost of 9 yards can be written as: -9 (As shown in the provided figure)
Now it is given that the team had a combined gain or loss of 0 yards after the next play.
Let they gain or lost x score in next play.
-9 + x = 0
Add both the sides by 9
x = 9
It means team must gain 9 yards.
So, the integer represents the yards gained or lost on the next play is 9.
Now represent this on number line.
Move 9 digit right to -9.
The required number line is shown in figure 1:

Answer:
As you must know, If one root of the polynomial 7-√5, the other will be 7+√5 i.e irrational root occur in pairs.
A polynomial function cannot have single unreal i.e irrational root. It always occur in pairs.
So , consider a polynomial function of any degree, if it has a root 7-√5, then it must have another root as 7+√5.
A polynomial can't have 7-√5 as a single root.
