I will give a brainlist

Answers

Answer:

10 and -10

Step-by-step explanation:

Absolute value is the distance of a number from 0. Absolute value must be positive because you can not a have a negative distance from 0. The two numbers that have a distance of 10 from 0 on the number line are 10 and -10.

Answer:

The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10.

Answers

Answer:

x=50

Step-by-step explanation:

A= 30+2x

B= x

Supplementary angles are angles that always add up to 180 degrees.

therefore, A + B=180 degrees

30 + 2x + x = 180: Now we solve

30 + 3x =180

subtract 30 from both sides

3x=150

divide by 3

3x/3 = 150/3

x= 50

9. What four consecutive integers have a sum of -34?

Answers

Given,

The four numbers are consecutive

The numbers are

x

x + 1

x + 2

x + 3

Sum = -34

x + (x + 1) + (x + 2) + (x + 3) = -34

x + x + 1 + x + 2 + x + 3 = -34

(x + x + x) + (1 + 2 + 3) = -34

3x + 6 = -34

3x = -34 - 6

3x = -40

x = -40/3

What is the value of x?

Answers

Answer:

2.20

Step-by-step explanation:

gil borrows $8000 for college expenses. he will pay a total of $2280 back in interest after 6 years. what was his interest rate

Answers

Answer:

R = 41.8129%/year

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving our equation:

r = (1/6)((8000/2280) - 1) = 0.41812865

r = 0.41812865

Converting r decimal to R a percentage

R = 0.41812865 * 100 = 41.8129%/year

The interest rate required to get a total amount, principal plus interest, of $8,000.00 from simple interest on a principal of $2,280.00 over 6 years is 41.8129% per year.

Step-by-step explanation:

Answer:

I believe it is 4.75 %

Step-by-step explanation:

2,280 × 100 = 228,000

228,000 / 8,000 = 28.5

28.5/6 = 4.75 %

find the number of words with or without meaning , which can be made by using all the letters of word ganga

Answers

Answer:

There are total 5 letters , of which A occur two times and G occur 2 times

Therefore , The number of permutations starting with A is 4! i.e 24

Thus , 25th word will be start from G i.e GGAAN

By rearranging according to the dictionary , we get

The 26th word will be GGANA

Hence , the 26th word is GGANA

Answer:

30

Step-by-step explanation

total number of letters in the word, n = 5

out of which G and A repeats 2 times each

p1 = p2 = 2

according to the equation of number of permutations,

= [tex]\frac{n!}{p_{1}! p_{2}! }[/tex]

total number of words = 5!/ (2! x 2!)

The difference of the squares of two positive consecutive even integers is 84. Find the integers.

Answers

Answer:

The two integers are 20 and 22.

Step-by-step explanation:

Let x be the first integer.

[tex](x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20[/tex]

Applying the difference of squares, and solving the equation, it is found that the numbers are 20 and 22.

----------------------

The two consecutive even integers are: n and n + 2.The difference of the squares is given by:

[tex]D_s = (n+2)^2 - n^2[/tex]

Expanding the difference:

[tex]D_s = n^2 + 4n + 4 - n^2[/tex]

[tex]D_s = 4n + 4[/tex]

----------------------

The difference is 84, thus:

[tex]D_s = 84[/tex]

Now, we solve for n.

[tex]4n + 4 = 84[/tex]

[tex]4n = 80[/tex]

[tex]n = \frac{80}{4}[/tex]

[tex]n = 20[/tex]

----------------------

Thus, the numbers are: [tex]n = 20[/tex] and [tex]n + 2 = 20 + 2 = 22[/tex]
