Answer:

s=2

Step-by-step explanation:

We are given the equation:

$26-4s=9s$

and asked to solve. We want to find out what the unknown variable, s, is. Therefore, we must isolate s on one side of the equation.

First, let's get all the terms with s on one side of the equation. 4s is being subtracted from 26. The inverse of subtraction is addition. Add 4s to both sides of the equation.

$26-4s+4s=9s+4s$

$26=9s+4s$

$26=13s$

s is being multiplied by 13. The inverse of multiplication is division. Divide both sides of the equation by 13.

$26/13=13s/13$

$26/13=s$

$2=s$

$s=2$

Let's check our solution. Plug 2 in for s and solve.

26-4s=9s

26-4(2)=9(2)

26-8=18

18=18

This checks out, so we know our solution is correct.

The solution to the equation 26-4s=9s is s=2.

What is the following difference 11 sqrt 45 - 4 sqrt 5

vampirchik [111]

Answer:

29*sqrt(5)

Step-by-step explanation:

Start with sqrt (45). You must reduce it to it's prime factors.

45: 9 * 5 9 is not prime so reduce it.

45: 3 * 3 * 5

When you write √45, you should replace it with √(3*3*5)

The rule is

Rule: when you have a pair of equal prime factors under a root sign, you can take one out and throw one away.

Rule 2: If there are an odd number of equal primes one of them will be left underneath the root sign.

√45 = 3√5

11sqrt(45) - 4 sqrt(5) Substitute for 45

11*3*sqrt(5) - 4sqrt(5) Take out sqrt(5) using the distributive property.

(11*3 - 4)*sqrt(5) Combine 11 * 3

(33- 4) * sqrt(5) Do the subtraction

Please Help!!!!!! Use what you've learned today about the sum of the interior angles of triangles and quadrilaterals to determin

sveta [45]

Answer:

m = 116

x = 24

y = 76

z = 40

Step-by-step explanation:

For startes the interior angles of triangles always add up to 180 degrees.

That means....

73 + 83 + x = 180

z + m + x = 180

z + y + 64 = 180

Another important fact is that two angles that are intersected by a line in the case 64 and m always add up to 180 degrees.

So m + 64 = 180

Let's start with 73 + 83 + x = 180

If you add 73 and 83 you get 156

x + 156 = 180 then subtract 156 from both sides and

x = 24

Then use m + 64 = 180 subtract 64 from both sides and

m = 116

z + m + x = 180 become

z + 116 + 24 = 180

Add 116 and 24 and you get 140

z + 140 = 180 subtract 140 from both sides and

z = 40

Check to make sure m + x + z = 180

24 + 40 + 116 = 180

z + y + 64 = 180 becomes

y + 40 + 64 = 180

40 + 64 = 104 so

y + 104 = 180 subtract 104 from both sides and

y = 76

Congratulations you have found all of the angles!

Given the system of equations, what is the solution? x 3y = 5 x - 3y = -1 {(-4, -3)} {(2, 1)} {(-2, 3)}

PSYCHO15rus [73]

The solution of the equation is (2, 1).

x=2 and y=1

<h3>What do you meant by equation?</h3>

A mathematical assertion that two expressions are equal is known as equating. It can be expressed as either an identity, in which case the variables can take on any value, or a conditional equation, in which case the variables can only have specific values (roots).

<h3>According to the given information:</h3>

We have two options for finding the answer. The first is to solve the equations via term elimination:

x + 3y = 5 ..............1

x - 3y = -1 ...............2

2x = 4 ..............3

With the equation, we can determine x. (3)

x = 4/2

x = 2

To determine y, we may now swap out x=2 in equation (1).

x + 3y = 5

2 + 3y = 5

3y = 3

y = 1

We've discovered x and y now.

x=2

y=1

The second method involves removing x from equation 1.

x + 3y = 5

x = 5 - 3y

In the equation right now, we may substitute x = 5 - 3y......... (2)

x - 3y = -1

(5 - 3y) - 3y = -1

5 - 6y = -1

6y = -6

y = 1

Currently, we can change y=1 in equations (1), (2), or (4) to find x.

We'll apply the equation (1)

x + 3y = 5

x + 3(1) = 5

x + 3 = 5

x = 2

The two variants x = 2 and y = 1 have allowed us to confirm this.
