Answer:
-5
Step-by-step explanation:
Let's assume the you are moving horizontally along the number line. If you start at -4 and jump to -6, you have made 2 jumps to the left(-4;-5;-6). So halfway between them (the midpoint) is 1 jump (half of 2 jumps).
1 jump to the left of -4.... You land at -5.

The value of x from the expression given is - 5
What are algebraic expressions?Algebraic expressions are expressions composed of variables, terms, factors, coefficients and constants.
They are also made up of mathematical operations such as addition, subtraction, division, multiplication, etc.
Given the expression, let's find the value of x
3(x + 1) = 2(x - 1)
Expand the bracket
3x + 3 = 2x - 2
collect like terms
3x - 2x = -2 - 3
Subtract like terms
x = - 5
Thus, the value of x from the expression given is - 5

A rocket flies 10 km vertically, then 20 km at an angle of 15° to the vertical and finally 60 km at an angle of 26° to the vertical. Calculate the vertical height of the rocket at the end of the third stage.
The vertical height of the rocket at the end of the third stage is 83.2 km.
We are provided that the rocket travels first 10 km vertically up (OA), then the rocket travels for 20 km (AC) at an angle of 15° from point A.
Let rocket travels 'a' distance vertically up(AB) during this,
then, rocket travels for travels for 60 km (CD) at an angle of 26° from point C.
Let rocket travels ' b' distance vertically up (BX) during this.
So,
Total Vertical Height Covered = 10 + a + b
So, According to diagram
In ΔABC
[tex]cos \ 15[/tex]° [tex]= \frac{a}{20}[/tex]
[tex]\\a = 20 * cos 15[/tex]° = 19.32km
In ΔCDE
[tex]cos \ 26[/tex]° [tex]= \frac{b}{60}[/tex]
[tex]\\b = 60 * cos 26[/tex]° = 53.9km
Since,
Total Distance = 10 + a +b
Total Distance = 10 + 19.32 + 53.9
Total Distance = 83.2 km
Therefore, Vertical height of the rocket at the end of third stage = 83.2 km

Using it's concept, the probability of at least 1 red face upper most is 17/18 = 0.9444 = 94.44%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For each cube, the probability of no red faces is:
Cube A: 1/6.Cube B: 3/6 = 1/2.Cube C: 4/6 = 2/3.Hence the probability of no red faces in anu cube is:
1/6 x 1/2 x 2/3 = 1/18.
Which means that the probability of at least 1 red face is given by:
1 - 1/18 = 17/18 = 0.9444 = 94.44%.

Given: triangle ABC,
Angle B=120°,
AB= 6, BC = 10
Find: The area of triangle ABC
The area of triangle ABC when Angle B=120°, AB= 6, BC = 10 is 25.980 square unit.
As per the question statement, we are supposed to find out the area of triangle ABC in which angle B=120°, AB= 6, BC = 10.
Lets find out AC for which we should know about Cosine formula
i.e., [tex]AC^{2} =AB^{2} +BC^{2} -2(AB)(BC)cos(B)\\AC^{2} =6^{2} +10^{2} -2*6*10cos120\\AC^{2}= 36+100-120*(-0.5)\\AC^{2}=196\\AC=\sqrt{196} =14[/tex]
Hence We have measures of all three sides of the triangle ABC.
Now we use the Heron's formula for calculating the area of triangle ABC.
We need semi perimeter i.e., [tex]s=\frac{AB+BC+AC}{2}[/tex]
[tex]s=\frac{30}{2} =15[/tex]
Now Area is given by,
[tex]area=\sqrt{s(s-AB)(s-BC)(s-AC)} \\area=\sqrt{15(15-6)(15-10)(15-14)} \\area=\sqrt{15*9*5*1} \\area=\sqrt{675} \\area = 25.980 unit^{2}[/tex]
Area: The space occupied by an object or a shape in square units.Cosine Formula: Uses the cosine of an angle to determine the remaining sides of the triangle.Heron's Formula: Uses the measure of the all sides of triangle to calculate the area of the triangle.To learn more about Heron's questions, click on the link given below:

If angle 5 is 120 degrees, find the value of <8
Answer:Answer:
The measurement of the angle is 60
Step-by-step explanation:
The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore
Angle 5 + angle 6 = 180
If angle 5 is 120 degrees, then
Angle 6 = 180 - 120 = 60 degrees.

The simplified form of the algebraic expression is [tex]\frac{23}{10} p+\frac{6}{5} r[/tex] .
An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).
A good example of an algebraic expression is 3x² + 2xy + c.Any expression that can be converted into a rational fraction using the properties of the arithmetic operations is said to be rational (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions). In other terms, a rational expression is one that can be created using only the four arithmetic operations and the variables and constants.Given expression is of the form:
[tex]\frac{3}{5} (\frac{1}{2}p+2r )+2p[/tex]
Now we will use the distributive property to expand the algebraic expression:
[tex]or, (\frac{3}{5} \times\frac{1}{2}p+\frac{3}{5} \times2r) +2p\\\\or,\frac{3}{10}p+\frac{6}{5} r+2p\\ \\or,\frac{3+20}{10} p+\frac{6}{5} r\\\\or,\frac{23}{10} p+\frac{6}{5} r[/tex]

HELP ME SOLVE PLEASEEEE
Answer: It is m<U = 60 and m<V = 120 (x = 20)
Step-by-step explanation:
1. We know that these 2 angles are supplementary, which means both adds up to 180 degrees.
2. So first, we do this:
3x + 2(m<U) = 180
2a. We do this to find m<U
3. We can also notice that 3x is m<U, so substituting m<U with 3x makes sense. 3x + 2(3x) = 180
4. We then simplify:
3x + 6x = 180
9x = 180
5. We will then divide:
x = 20
6. With the new found info, we substitute x with 20:
m<U = 3(20)
m<V = 2(3(20))
7. Doing the math, it becomes:
m<U = 60
m<V = 120

The probability that the bolt will be inserted in 19 minutes or less is 0.8413.
How to calculate the probability?It should be noted that the probability will be illustrated as:
P(X < x) = P[z < (x - u/sd)]
where
x = number
u = mean
SD = standard deviation
Therefore given the numbers, this will be:
P(x < 19) = P(z < (19 - 15)/4)
= P(z < 4/4) = P(z < 1)
= 0.8413

There is no relationship between the number of movies and the number of sleep hours.
What is a relationship?It is always a thing of importance to show data by the use of a scatter plot. The scatter plot must always have two axes. The vertical (y axis ) and the horizontal (x axis). It is always common to plot the independent variable on the x axis and the dependent variable on the y axis.
The scatter plot thus represented shows how one variable is related to another. In this case, we are trying to obtain how the number of sleep hours tend to be related with the number of movies and this has been shown on the scatter plot that is shown in the question above.
It is clear from the statements in the question that the line of best fit would show that as the number of movies remained constant, the number of sleep hours decreased. This now implies that there is no relationship between the number of movies and the number of sleep hours.
