Answer:
Step-by-step explanation:
Start at 1 1/3
Add the negative number.
1 1/3 + (-5/6)
Adding a negative number means to go left on a number line.
-5/6 is equal to -2/3 plus -1/6.
Move 2/3 to the left.
1 1/3 (Start)
1 (1/3)
2/3 (2/3)
Now, move 1/6th to the left.
2/3 is equal to 4/6
4/6 - 1/6 = 3/6
So, put the point at 3/6 or 1/2.
The value of addition of 1 1/3+(−5/6) is 1/2 and plotted on a number line.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
Start at 1 1/3
Add the negative number;
1 1/3 + (-5/6)
Here Adding a negative number means to go left on a number line.
-5/6 is equal to -2/3 plus -1/6.
Now Move 2/3 to the left;
1 1/3 (Start)
1 (1/3)
2/3 (2/3)
Now, move 1/6th to the left;
2/3 is equal to 4/6
4/6 - 1/6 = 3/6
Thus 1 1/3+(−5/6) = 3/6 = 1/2
The value of addition of 1 1/3+(−5/6) is 1/2 and plotted on a number line.

Solve the equation. | 3k-2 | = 2| k+2 |
Answers
Answer:
[tex]-2/5 \text{ and } 6[/tex]
Step-by-step explanation:
So we have the equation:
[tex]|3k-2|=2|k+2|[/tex]
First, distribute the 2 into the absolute value:
[tex]|3k-2|=|2k+4|[/tex]
Definition of absolute value:
[tex]3k-2=(2k+4) \text{ or } 3k-2=-(2k+4)[/tex]
Left:
[tex]3k-2=2k+4[/tex]
Subtract 2k from both sides:
[tex]k-2=4[/tex]
Add 2 to both sides:
[tex]k=6[/tex]
Right:
[tex]3k-2=-(2k+4)[/tex]
Distribute the negative:
[tex]3k-2=-2k-4[/tex]
Add 2k to both sides:
[tex]5k-2=-4[/tex]
Add 2:
[tex]5k=-2[/tex]
Divide by 5:
[tex]k=-2/5[/tex]
So, our solutions are:
[tex]-2/5 \text{ and } 6[/tex]
3p + 4r = q solve for p
Answers
Answer:
[tex] p = \dfrac{q - 4r}{3} [/tex]
Step-by-step explanation:
3p + 4r = q
3p = q - 4r
[tex] p = \dfrac{q - 4r}{3} [/tex]
Answer:
[tex]p=\frac{q}{3} - \frac{4}{3}r[/tex]
Step-by-step explanation:
If we want to solve for p, our ultimate goal is to isolate it one one side of the equation.
Given [tex]3p + 4r = q[/tex], we can do a few actions on it to isolate the variable.
Divide both sides by 3:
[tex]p + \frac{4}{3}r = \frac{q}{3}[/tex]
Subtract [tex]\frac{4}{3} r[/tex] from both sides:
[tex]p = \frac{q}{3} - \frac{4}{3}r[/tex]

how do you add and subtract integers?
Answers
Answer: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:
The number line is shown below.
Step-by-step explanation:
We need to represent number that is less than 3 on a number line.
Let x be numbers.
So, [tex]x<3[/tex].
Now, we have a number which represents x<3. Here 3 is not included in the solution set, so there is an open circle on 3 and left side of 3 are in the solution set.
The number line is shown below.

Answers
Answer:
the Empty set
Step-by-step explanation:
Recall that the intersection of two sets is another set that contains the elements common to both of the intersected sets.
Since sets A and C have NO element in common, then the answer is:
that the intersecting set is: the Empty set.
Answer:
the empty set
Step-by-step explanation:
this simbol ∩ is the intersection and it works as follows
[tex]X={1,2,3}\\\\Y={2,5,6,3}\\\\[/tex]
and X∩Y={2, 3}
because 2 and 3 are the only ones that are in both sets
so we have
A={a, e, i, o, u}
B={a, l, g, e, b, r}
C={m, y, t, h}
A∩C= the empty set
because A and C don't have any common subset

The length of one leg of the right triangle is 2 ft less than the length of the hypotenuse. The length of the other leg is 1 ft less than the length of the hypotenuse. Find the length of the sides.
Answers
Answer:
The length of the sides are 3 feet and 4 feet, respectively.
Step-by-step explanation:
Given the fact that triangle is a right triangle, it can be represented by Pythagorean Theorem:
[tex]r^{2} = x^{2}+y^{2}[/tex]
Where:
[tex]r[/tex] - Hypotenuse, measured in feet.
[tex]x[/tex], [tex]y[/tex] - Legs, measured in feet.
In addition, each leg can be determined as functions of hypotenuse:
[tex]x = r-2\,ft[/tex]
[tex]y = r-1\,ft[/tex]
Hence, the Pythagorean identity can be expanded and remaining variable may be solved:
[tex]r^{2} = (r-2\,ft)^{2}+(r-1\,ft)^{2}[/tex]
[tex]r^{2} = r^{2}-4\cdot r +4 + r^{2}-2\cdot r +1[/tex]
[tex]r^{2}-6\cdot r +5 =0[/tex]
[tex](r-5)\cdot (r-1) = 0[/tex]
[tex]r = 5\,ft\,\vee\,r = 1\,ft[/tex]
According to the definition of hypotenuse, it must be longer than any of legs. Hence, there is just one solution that is reasonable:
[tex]r = 5\,ft[/tex]
And length of the sides are, respectively:
[tex]x = 5\,ft-2\,ft[/tex]
[tex]x =3\,ft[/tex]
[tex]y = 5\,ft-1\,ft[/tex]
[tex]y = 4\,ft[/tex]
The length of the sides are 3 feet and 4 feet, respectively.

Which is not an equation of the line going through (6,7) and (2,-1) A. y-7=2(x-6) B. y=2x-5 C. y-1=2(x+2) D. y+1=2(x-2)
Answers
Answer:
C. y-1=2(x+2)
Step-by-step explanation:
A. y-7=2(x-6)-point slope form: y-y1=2(x-x1)-coordinate point: (x1,y1)=(6,7)
Now let's check that the other point works-just sub in the coordinates for the x and y variables.
y-7=2(x-6)\\-1-7=2(2-6)\\-8=2(-4)\\-8=-8
So answer choice A. goes through both points, so no.
B. y=2x-5-slope-intercept form, so just sub in both sets of coordinates separately to see if they each work.
y=2x-5\\7=2(6)-5\\7=12-5\\7=7\\equal
y=2x-5\\-1=2(2)-5\\-1=4-5\\-1=-1\\equal
Both work, so no.
C. y-1=2(x+2)-point slope form that gives us first coordinate set--(-2,1)
Except that the point is actually (2,-1) not (-2,1). That means that answer choice C is not an equation of the line thaat goes through (6,7) and (2,-1), so yes.
D. Anyway, if we check D--y+1=2(x-2)--coordinate point given: (2,-1), which is correct, so no.

El promedio trimestral de Víctor en Matemática es 5,5. Durante el trimestre tuvo 4 calificaciones en esta asignatura: dos notas 6,0, una nota 4,8 y otra que no recuerda. ¿cuál es la nota que Víctor no recuerda?
Answers
Answer:
La nota que Víctor no recuerda es 5.2
Step-by-step explanation:
La media es el valor promedio de un conjunto de datos numéricos y es también llamada promedio o media aritmética.
Su cálculo se obtiene al sumar todos los datos disponibles y dividir el resultado por el número total de esos datos:
[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+...+x_{n} }{N}[/tex]
donde N el número total de observaciones.
En este caso:
[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+x_{4} }{4}[/tex]
Siendo:
Promedio= 5.5x₁=6x₂=6x₃=4.8x₄=?y reemplazando:
[tex]5.5=\frac{6 +6 +4.8+x_{4} }{4}[/tex]
Se obtiene:

22=6+6+4.8 +x₄
22-6-6-4.8=x₄
x₄=5.2

Answer: 20
Step-by-step explanation:
Assuming for every line you go up you increase the by 2.
So if you have 8 you skip a line and you end up at 12 the next line the line in between those 2 numbers should be 10. Leaving you with a sequence of numbers and if you keep going along 12, 14, 16, 18, you arrive at 20.
A bowl contains candies of the same size in three flavors: orange, strawberry, and pineapple. If the probability of randomly pulling out an orange candy is 1 over 7 , and the probability of randomly pulling out a strawberry candy is 2 over 7 , what is the probability of randomly pulling out a pineapple candy?
Answers
So if you already know that you have a 1 in 7 chance of pulling a orange, and a 2 in 7 chance of pulling a strawberry, then the other 4 candies in the bowl will be pineapple.
Therefore the probability of pulling out a pineapple candy would be 4 out of 7.
