I need help I got -9.125 but the calculator says -9. Here is the problem. Please help ASAP
-8-5n=64+3n

Answers

Answer 1

Answer:

n= -9

Step-by-step explanation:

The calculator is correct haha, You're welcome.

Answer 2
Answer:

n=-9

Explanation:
In order to solve for x, we must get x by itself on one side of the equation.
The equation is:
-8-5n=64+3n
5n is being subtracted and the inverse of subtraction is addition. Add 5n to both sides of the equation.
-8-5n+5n=64+3n+5n
-8=64+3n+5n
-8=64+8n
64 is being added and the inverse of addition is subtraction. Subtract 64 from both sides of the equation.
-8-64=64-64+8n
-8-64=8n
-72=8n
n is being multiplied by 8. The inverse of multiplication is division. Divide both sides of the equation by 8.
-72/8=8n/8
-72/8=n
-9=n

The solution to the equation is n=-9

Which symbol correctly compares the fractions?

−5/6 −13/15

a. >

b. <

c. =

Answers

a. > because if set them to have an equal denominator the fractions would be -25/30 and -26/30 and -25/30 is greater then -26/30 because it is less negative

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

For us to compare negative fractions, we must know that higher negative fractions are less than the smaller ones

Given the fractions  −5/6 and −13/15

First we will need to write this fractions as percentage:

-5/6 * 100 = -500/6 = -83.3%

-13/15 * 100 = -1300/15 = -86.67%

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

Use the figure to find measures of the numbered angles.

Answers

Answer:

1 = 137

2 = 43

3 = 43

4 = 137

Step-by-step explanation:

for the first line, do (180-137 = 43)

then, 43 would be corresponding angle to 2 - making them equal

2 would be vertically opposite to 3, making them equal

137 and 1 are corresponding- making them equal

4 is vertically opposite to 1 - making them equal

Angle 1 = 137 degrees
Angle 2 = 43 degrees
Angle 3 = 43 degrees
Angle 4 = 137 degrees

Answer:

68.7 - t

Step-by-step explanation:

Here, we are interested in giving the expression that Kalinda can use to know the difference in height between her and Terrence

From the question, Kalinda is 68.7 inches tall while Terrence is t inches tall

To know the difference in their heights, we simply subtract Terrence’s height from Kalinda’a

Mathematically, that would be 68.7 - t

1 point
2x + 5 ft
6x – 11 ft
Your answer
This is a required question

Answers

Answer:

The length of one side is 13 feet.

Step-by-step explanation:

To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:

[tex]2x+5=6x-11[/tex]

In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:

[tex]5=4x-11[/tex]

After that, you solve it like a normal one-step equation. Add 11 to both sides.

[tex]16=4x[/tex]

Now, divide both sides by 4 and you will know how much [tex]x[/tex] is worth.

[tex]4=x[/tex]

Now that we know how much [tex]x[/tex] is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.

[tex]2(4)+5[/tex]

That would give us 13.

Answer:

the sides are 13

x= 4

Step-by-step explanation:

2x+5 = 6x-11     subtract five from both sides

2x = 6x-16        subtract 6x from both sides

-4x = -16           divide both sides by -4

x = 4                substitute into original problem

2(4) + 5 = 6(4) - 11

8 + 5 = 24 - 11

13 = 13

Are the expressions –0.5(3x + 5) and –1.5x + 2.5 equivalent? Explain why or why not.​

Answers

Answer:

It is

-0.5(3x+5)= -1.5x+2.5

Step-by-step explanation:

-0.5(3x+5)

multiply-0.5 with 3x and 5 to get rid of the brackets.

-0.5×3x= -1.5x

-0.5×5= 2.5

-1.5x+2.5

Answer:

Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

Answers

Answer: x=1

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3*x+2*(5*x-3)-(7)=0

3x + 2 • (5x - 3)) - 7 = 0

Pull out like factors :

13x - 13 = 13 • (x - 1)

13 = 0

A a non-zero constant never equals zero.

Solve : x-1 = 0

Add 1 to both sides of the equation :

x = 1

Given:

Two triangles are congruent, i.e., [tex]\Delta ABC\cong \Delta XYZ[/tex].

To find:

All the measures of both triangle.

Solution:

We have,

[tex]\Delta ABC\cong \Delta XYZ[/tex].

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

[tex]\angle A=\angle X[/tex]

[tex]\angle B=\angle Y=90^\circ[/tex]

[tex]\angle C=\angle Z=37^\circ[/tex]

It triangle ABC,

[tex]\angle A+\angle B+\angle C=180^\circ[/tex]     (Angle sum property)

[tex]\angle A+90^\circ+37^\circ=180^\circ[/tex]

[tex]\angle A+127^\circ=180^\circ[/tex]

[tex]\angle A=180^\circ -127^\circ[/tex]

[tex]\angle A=53^\circ[/tex]

So,

[tex]\angle A=\angle C=53^\circ[/tex]

[tex]AB=XY=3\text{ units}[/tex]

[tex]BC=YZ=4\text{ units}[/tex]

[tex]AC=XZ=5\text{ units}[/tex]

Therefore, m∠A = 53˚,  m∠B =90˚ , m∠C =37˚ , m∠X = 53˚,  m∠Y =90˚ , m∠Z =37˚ , Segment AB = 3 units , Segment BC = 4 units , Segment AC = 5 units , Segment XY = 3 units , Segment YZ = 4 units , Segment XZ = 5 units .

Ibai has taken 2/5 out of a barrel of beer, Ane has drawn a third. It expresses in graphic and numerical form: a) The fraction that they have drawn between the two. b) Which of them has gotten the most?

Answers

Answer:

7/15

Step-by-step explanation:

2/5 + 1/3 is the same as 2/5 + 5/15.. so we add them together to get 7/15. This can not be simplified further

To know who has gotten most I like to think in percentage terms. 2/5 is the same as 40% (2/5 is the same as 4/10 = 40/100 =40%). 1/3 is 33.33% so Ane got more

Answer:

A. 11/15 B. Ibai.

Step-by-step explanation:

First, find the Least Common Multiple, or LCM, of the denominators, which is 15. Then, multiply each denominator by the number that gets the denominator to 15, which is the LCM. Next, multiply the numerator by the same number you multiplied the denominators, which was 3 for Ibai, and 5 for Ane. Finally, compare the two numbers to see which is higher. In this case, Ibai took out 6/15, while Ane took out 5/15, meaning Ibai took out more than Ane. Also, together, Ibai and Ane both drew out 11/15 together.

An end behavior model for f(x) = (shown in attachment) is g(x) =​

Answers

Answer:

2x^4

Step-by-step explanation:

As the magnitude of x gets larger, the absolute value of x gets large

The higher degree terms are going to grow much faster than the lower degree terms, so that is what we need to focus on

The highest degree terms here in the numerator and denominator are 8x^6 and 4x^2, so let's divide the two, and simplify to get our solution;

f(x) = (8x^6) / (4x^2)

= 2x^6 / x^2 = 2x^(6 - 2)

= 2x^4 (solution)
