if 2x+8=16, what is the value of x+4?​

Answers

Answer 1

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{8}}}}}[/tex]

Step-by-step explanation:

First, finding the value of x

[tex] \sf{2x + 8 = 16}[/tex]

Move 8 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{2x = 16 - 8}}[/tex]

Subtract 8 from 16

[tex] \dashrightarrow{ \sf{2x = 8}}[/tex]

Divide both sides by 2

[tex] \dashrightarrow{ \sf{ \frac{2x}{2} = \frac{8}{2} }}[/tex]

Calculate

[tex] \dashrightarrow{ \sf{x = 4}}[/tex]

Value of x is 4

Now, Substituting / Replacing the value of x in order to find x+4

[tex] \sf{x + 4}[/tex]

plug the value of x

[tex] \dashrightarrow{ \sf{4 + 4}}[/tex]

Add the numbers : 4 and 4

[tex] \dashrightarrow{ \sf{8}}[/tex]

Hope I helped!

Best regards! :D

find the distance between points (2,5) and (-2,2)

Answers

Answer:

5

Step-by-step explanation:

Let :

x(1) be 2

y(1) be 5

x(2) be -2

y(2) be 2

We know that distance between any 2 points is equal to:-

[tex] \sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} } [/tex]

So using the above formula ,

[tex] \sqrt{ {( - 2 - 2)}^{2} + {(2 - 5)}^{2} } [/tex]

[tex] = > \sqrt{ {( - 4)}^{2} + {( - 3)}^{2} } [/tex]

[tex] = > \sqrt{16 + 9} [/tex]

[tex] = > \sqrt{25} = 5[/tex]

Which equation could be used to create the graph

Answers

Answer: y = x/3

Explanation:

The graph has a slope of 1/3 and a y-intercept at (0,0).

Using the form y = mx + b, where m is the slope of the line and b is the y-coordinate of the y-intercept, the equation for the line is y = x/3.

we have 10 marbles. five are blue Five are red. we select three marbles. what are the odds (in percent) that all three chosen are red?

Answers

Answer:

12.5%

Step-by-step explanation:

Step 1:

We need to find out the percentage of picking a marble that is red. In total, there are 10 marbles, and there are 5 red. To find the probability of picking a red marble, you need to do:

# of red / total marbles.

There are 5 red marbles and 10 total marbles, so the probability of getting a red marble is 5/10, and you can simplify it to 1/2 (5/10 * 5/5).

Step 2:

Now we can start finding the probability of finding the probability of choosing three red marbles in a row. Since we need to find the probability of choosing red marbles three times, you can multiply 1/2 by itself 3 times (1/2 * 1/2 * 1/2).

1/2 * 1/2 * 1/2 = 1/8

Step 3:

Now we need to convert the fraction into a percentage. You can find the percentage by dividing 1 by 8. You should get 0.125, and you can multiply 0.125 by 100, and your final answer should be 12.5%.

The two figures below, a regular hexagon and a regular pentagon, have the same
perimeter. What is the length of a side of the pentagon?

Answers

Answer:

69

Step-by-step explanation:

Perimeter = sum of all sides of a regular polygon = the number of sides*length of a side

Length of a side of the given regular hexagon = 3x + 5

Perimeter of hexagon = 6(3x + 5) = 6(3x) + 6(5) = 18x + 30

Length of a side of the given regular pentagon = 4x - 1

Perimeter of pentagon = 5(4x - 1) = 5(4x) - 5(1) = 20x - 5

Since we are told that the perimeter of the regular hexagon is the same as that of the regular pentagon, therefore:

18x + 30 = 20x - 5

Solve for x.

Subtract 20x from both sides

18x + 30 - 20x = 20x - 5 - 20x

-2x + 30 = -5

Subtract 30 from both sides

-2x+ 30 - 30 = -5 - 30

-2x = -35

Divide both sides by -2

x = -35/-2

x = 17.5

Length of a side of pentagon = 4x - 1

Plug in the value of x

4(17.5) - 1 = 70 - 1 = 69

length of a side of the pentagon = 69

What is the slope of the line that contains these points? x| -7. -6. -5. -4 ------------------------------------------------------------- y| 21. 17. 13. 9

Answers

Answer:

-4

Step-by-step explanation:

Given the line containing the points.

x | -7. -6. -5. -4

y | 21. 17. 13. 9

The slope of the line is expressed as m = Δy/Δx = y₂-y₁/x₂-x₁

Using the coordinates y (21, 17) and corresponding value of  x(-7, -6)

y₁ = 21, y₂ = 17 x₁ = -7, x₂ = -6

Substituting the values into the formula for calculating the slope, we have;

m = Δy/Δx = 17-21/-6-(-7)

m = -4/-6+7

m = -4/1

m = -4

Hence the slope of the line that contains these points is -4

4. Factor x2 - 4x – 32.

Answers

Answer:

(x - 8)(x + 4)

Step-by-step explanation:

We need to find something that multiplies to 32 and adds up to 4.

The 2 special numbers would be -8 and 4.

-8(4) = -32

-8 + 4 = -4

We then simply write out the factored form:

(x - 8)(x + 4)

Answer:  (x+4)(x-8)    

Step-by-step explanation:

x^2 - 4x -32         Find two numbers that their product is -32 and their sum is -4. The numbers -8  and 4 will work out because -8 times 4 is -32 and -8 plus 4 is -4.

Now rewrite the whole polynomial as

x^2 +4x -8x -32     Now group them  

(x^2 +4x)  (-8x -32)    Now factor each side

x(x +4)   -8(x +4)         factor out x+4

(x+4)(x-8)

4. Converse of Corresponding Angles Postulate

Step-by-step explanation:

There are several theorems to prove line relationships in plane geometry.

The proof of parallel lines is done by

(3) Converse of Corresponding Angles Postulate(4) Converse of Same-Side Interior Angles Theorem

To prove that lines are parallel, we make use of the concept of line transversal.

The vertical angle theorem is based on two lines intersecting at a point

The alternate interior angle theorem is used to determine the congruence of angles in a transversal of parallel lines

The converse of corresponding angles postulate, and the converse of same-side interior angles theorem are used to determine if lines are parallel based on the angles on the transversal.

Hence, the true options are (3) and (4)

∠ D = 48°

Step-by-step explanation:

Since AC ~ BC then Δ ABC is isosceles and the base angles are equal, thus

∠ B = ∠ C = 69°, then

∠ ACB = 180° - (69 + 69)° = 180° - 138° = 42° ( sum of angles in Δ )

∠ DCE = ∠ ACB = 42° ( vertical angles )

∠ D = 180° - (90 + 42)° = 180° - 132° = 48°

Shawna is making smoothies. The recipe calls for two parts yogurt to three parts blueberry. Shawna wants to make 10 cups of smoothie. Mix how many cups of yogurt and blueberries does Shawna need

Answers

Answer:

Shawna needs a mix of 4 cups of yoghurt and 6 cups of blueberries

Step-by-step explanation:

Here, we want to know the number of cups of yoghurt and smoothies Shawna needs to make;

We have 2 parts yoghurt and 3 parts blueberry, so we can say we have a ratio of 2:3

The total number of cups to be made is 10

So the number of cups of yoghurt will be;

2/(2+3) * 10

= 2/5 * 10 = 4 cups

The number of cups of blueberry would be;

3/5 * 10 = 6 cups

So a mix of 4 cups of yoghurt and 6 cups of blueberries is needed by Shawna
