Read the following statement: If A is an acute angle, then m2A = 30°. This statement demonstrates:

the substitution property.
the reflexive property. the symmetric property. the transitive property.

The factor which tarriq musr use if solving the equation using the multiplication property of equality to finish solving is 2.

The correct answer option is option D

Tarriq solution:

50 + 2x = –190

50 + 2x = –190

50 – 50 + 2x = –190 – 50

2x = –240

Correct solution:

50 + 2x = –190

Subtract 50 from both sides

50 - 50 + 2x = -190 - 50

2x = - 240

divide both sides by 2

x = -240/2

x = -120

In conclusion, x = -120 is the solution to tarriq equation if using multiplication property of equality.

Answer: 0.03 pounds

Step-by-step explanation:

To determine how much trail mix went in each bag, you need to divide the total amount of trail mix by the number of bags.

In this case, you would divide 3 pounds of trail mix by 10 bags to find that each bag contained 0.3 pounds of trail mix.

You can also express this amount in ounces. Since there are 16 ounces in a pound, each bag contained 4.8 ounces of trail mix (0.3 pounds * 16 ounces/pound = 4.8 ounces).

Answer:

x = 145°

X is an algebraic variable which has no defined value. X is kind of universe variable taken in most of the equations.

The value of x in the solution set of - 5x - 15 > 10 + 20x is x < - 1 and the required value from the solution set is -2.

Solution:

Given: - 5x - 15 > 10 + 20x

Let us solve the inequality by isolating the variable x.

Add 5x on both sides

- 5x - 15 + 5x > 10 + 20x + 5x

- 15 > 10 + 25x

Subtract 10 from both sides

- 15 - 10 > 10 - 10 + 25x

- 25 > 25x

Divide both sides by - 25

-1 > x

x < - 1

The value of x in the solution set of - 5x - 15 > 10 + 20x is x < - 1 and the required value from the solution set is -2.

Increasing, as the slope is positive (1/2)

Answer:

Increasing.

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Given linear equation:

[tex]y=\dfrac{1}{2}x+2[/tex]

Comparing the given linear equation with the slope-intercept formula, the slope of the given equation is ¹/₂.

The graph of a linear equation is increasing if its slope is positive.

(y-values increase as x-values increase).

The graph of a linear equation is decreasing if its slope is negative.

(y-values decrease as x-values increase).

Therefore, as the slope of the given linear equation is positive, its graph is increasing.

To determine whether the system of equations is consistent and independent, consistent and dependent, or inconsistent, we need to first solve the system of equations to find the value of x and y that satisfy both equations.

To solve the system of equations, we can first solve the first equation for y:

y = −3x + 1

Next, we can substitute this expression for y into the second equation and solve for x:

2y = −6x + 2

2 * (−3x + 1) = −6x + 2

−6x + 2 = −6x + 2

0 = 0

Since the two equations are equivalent, the system of equations is consistent and dependent, meaning that there is only one possible solution (x = 0, y = 1) that satisfies both equations.

The primary eight candles or oil lamps must be on a plane that is higher or lower than the shamash.

A nine-branched candelabrum known as a Hanukkah menorah, also known as a hanukkiah, is lighted during the eight-day Jewish festival of Hanukkah. Eight of the nine branches are held up by lights (candles or oil lamps), which stand throughout the eight nights of the festival. One additional light is lighted each night until all eight branches are illuminated on the last night. The candle on the ninth branch, known as the shamash (Arabic for "helper" or "servant"), is used to light the other eight branches.

The variables x, y, z associated to the parallelogram are equal to 60, respectively.

A parallelogram is a quadrillateral formed by two pairs of parallel sides. The figure shows a parallelogram since the following relationships are met: BC ║ AD, AB ║ CD. We need three equations to determine the values of x, y and z and this can be obtained by means of parallelogram properties:

y = x

y + (x + y) = 180°

z + (x + y) = 180°

First, substitute x on the second and third equations:

3 · y = 180°

z + 2 · y = 180°

Second, find y:

y = 180° / 3

y = 60

Third, find z:

z = 180° - 2 · y

z = 180° - 2 · 60

The number of coach tickets is; 3 coach tickets

The number of first class tickets is; 8 first class tickets

We are told that she took 11 people on the trip.

Let the number of first class tickets be f

Let the number of coach tickets be c

Thus;

c + f = 11  -----(1)

She was able to purchase coach tickets for $180 and first class tickets for $1200. She used her total budget for airfare for the trip, which was $10,140. Thus;

180c + 1200f = 10140   -----(2)

Make c the subject in eq 1 to get;

c = 11 - f

Put 11 - f for c in eq 2 to get;

180(11 - f) + 1200f = 10140

1980 - 180f + 1200f = 10140

1020f = 8160

f = 8

Multiplication is a mathematical operation in which one number is multiplied by another. It is usually used to calculate the product of two or more numbers. It is an important operation in mathematics and is used in a variety of ways, including calculating the area of a rectangle, the volume of a cube, and the total cost of items purchased at a store. Multiplication is often represented by the multiplication symbol, which is usually an 'x' or an asterisk (*). When two numbers are multiplied, the result is called the product. For example, if two numbers are multiplied together, the product is the answer to the question "what is the result of multiplying these two numbers together?"

y = x + 2

Remember that a general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

First, we know that one of the lines has an y-intercept at y = 1, then:

y = a*x + 1

And the line passes through (1, 3), replacing these values we get:

3 = a*1 + 1

3 - 1 = a

2 = a

That line is y = 2*x + 1

The other line has a y-intercept at y = 2, then:

y = a*x + 2

Answer:

Step-by-step explanation:

C(x) = 3x + 65  Substitute in 7 for x

C(7) = 3(7) + 65

C(x) = 21 + 65

C(x) = 86

Answer

86 Dollars

Step-by-step explanation:

It is given that

[tex]c(x) = 3x + 65 \\ [/tex]

Since,x is the number of miles the car is towed which in this case is 7

So, If we input 7 in the function C(x)

[tex]c(7) = 3 \times 7 + 65[/tex]

We know through BODMAS that multiplication is done before addition.

Thus,

[tex]c(7) = 21 + 65 \\ because \: 3 \times 7 = 21 \\ [/tex]

and so,

[tex]c(7) = 86 \\ because \:21 + 65 = 86[/tex]

and so,

c(7) = 86

We also know that C(x) is the cost of having the car towed which is equal to 86 for the case of towing the car 7 miles

Thus,The cost of having the car towed 7 miles is 86 Dollars

64 observations were randomly selected at random from a population of 500. the population standard deviation is 16.The standard deviation of the sample mean is 4 (16/√64).

The standard deviation of the sample mean is calculated by dividing the population standard deviation (16) by the square root of the sample size (64).

Consequently, the sample mean's standard deviation is

16/√64 = 4.

This means that the expected spread of the sample means is 4, which is less than the population standard deviation of 16. This is because the sample is smaller than the population, so the sample standard deviation will be smaller than the population standard deviation.
