Answer:

10.3

105.6-95.3=10.3

When adding with a number and a negative, you can change the problem to a subtraction problem!!! If the negative is more than the positive, the number will become negative too!!! P.S. Please mark me Brainlist.

The sum of digits in a two digit number formed by two digits from 1 to 9 is 8. If 9 is added to a number then both the digits be
Arturiano [62]
<h2>Explanation:</h2><h2></h2>

Here we need to set a system of two linear equations in two variables. So:

  • <em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>

Let x \ and \ y be those digits, then:

x+y=8 \ \ldots eq1

  • <em>If 9 is added to a number then both the digits become equal. find the number:</em>

<em />

<em />10x+y+9 \ldots expression \ 1<em />

<em />

But from eq 1:

y=8-x

Substituting y into the expression 1:

10x+(8-x)+9=9x+17

The x-value will be found by hit and trial, so:

  • Let x = 1:

9x + 17 = 9(1)+17 = 26

We have to reject this solution because digits are different.

  • Let x = 2:

9x + 17 = 9(2)+17 = 35

We have to reject this solution because digits are different.

  • Let x = 3:

9x + 17 = 9(3)+17 = 44

<em>Then this is a two digit number formed by two equal digits. </em>

Finally, the number is:

44

Calculate the value of x.
mars1129 [50]

Answer:

49.2°

Step-by-step explanation:

To solve for x you'll need to find the cosine of x°.

To find the cosine you will need to divide the adjacent side to it by the hypotenuse.

cos x°= \frac{17}{26}

Using a calculator to solve you'll get that x ≈ 49.2°

Does the graph represent a function?
Harrizon [31]

Answer:

The graph does represent a function because it passes the vertical line test!

Step-by-step explanation:

A vertical line test means if you put a vertical line over any area on the graph it shouldn't hit the line more than once :)

An example of consecutive odd integers is 23, 25, 27, and 29. Find four consecutive odd integers with a sum of 160. Show your wo
Andrew [12]
Step1: Define an odd integer.
Define the first odd integer as (2n + 1), for n = 0,1,2, ...,
Note that n is an integer that takes values 0,1,2, and so no.

Step 2: Create four consecutive odd integers.
Multiplying n by 2 guarantees that 2n will be zero or an even number.
Therefore (2n + 1) is guaranteed to be an odd number.
By adding 2 to the odd integer (2n+1), the next number (2n+3) will also be an odd integer.

Let the four consecutive odd integers be
2n+1, 2n +3, 2n +5, 2n +7 

Step 3: require that the four consecutive integers sum to 160.
Because the sum of the four consecutive odd integers is 160, therefore
2n+1 + 2n+3 + 2n+5 + 2n +7 = 160
8n + 16 = 160
8n = 144
n = 18

Because 2n = 36, the four consecutive odd integers are 37, 39, 41, 43.

Answer: 37,39,41,43
