Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = 8

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to the exterior angle that's supplementary to the third interior angle:

7x + 6 + 22 = 9x + 12 add like terms

7x + 28 = 9x + 12 export like terms to the same side of the equation

28 - 12 = 9x - 7x

16 = 2x divide both sides by 2

8 = x

Answer:

4x

Step-by-step explanation:

64xyz =  2⁶ * x * y* z

36xy = 2² * 3² * x * y

24x   = 2³ * 3 * x

GCF = 2² *x = 4x

Answer:

128

Step-by-step explanation:

72 people are vegetarians so 200-72=128

IH + HJ = 2 (IH)

0.75 + HJ = 2(0.75)

0.75 + HJ = 1.5

HJ = 1.5 - 0.75

HJ = 0.75

Answer:

1.67 or 5/3

Hope this helps

Answer:

1 2/3

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{8}{5}[/tex]

Applying the fractions formula for division,

= [tex]\frac{8}{3} x \frac{5}{8}[/tex]

=[tex]\frac{40}{24}[/tex]

Simplifying 40/24, the answer is

1[tex]\frac{2}{3}[/tex]

Explanation:

I just did the test.

Answer:

C

Step-by-step explanation:

Answer:

1.) x = -1

2.) x = -4

Step-by-step explanation:

1.) 4(1 - 3x) + 7x = 9

=> Use distributive property:

4 - 12x + 7x = 9

=> Combine like terms:

4 - 5x = 9

=> Isolate 5x:

-5x = 5

=> Isolate x:

x = 5/-5

=> Simplify:

x = -1

2.) 9 - 5x = 12 - (6x + 7)

=> Use distributive property:

9 - 5x = 12 -6x - 7

=> Combine like terms:

9 - 5x = 5 - 6x

=> Isolate x to one side:

9 + x = 5

x = -4

Equation at the end of step 1

STEP

:

Trying to factor by splitting the middle term

2.1     Factoring  8x2-6x-3  

The first term is,  8x2  its coefficient is  8 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   8 • -3 = -24  

Step-2 : Find two factors of  -24  whose sum equals the coefficient of the middle term, which is   -6 .

     -24    +    1    =    -23  

     -12    +    2    =    -10  

     -8    +    3    =    -5  

     -6    +    4    =    -2  

     -4    +    6    =    2  

     -3    +    8    =    5  

     -2    +    12    =    10  

     -1    +    24    =    23  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 8x2 - 6x - 3

Step-by-step explanation:

Answer:

  c = -3; d = 5

Step-by-step explanation:

The function is differentiable if it is continuous and the derivative is continuous.

This function will be continuous if the limit as x approaches 3 from either side is the same. From the left, the limit is ...

  5(3^2) +c = 45 +c

From the right, the limit is ...

  d(3^2) -3 = 9d -3

__

The derivative will be continuous if the limit as x approaches 3 from either side is the same. From the left, the limit is ...

  f'(x) = 10x

  = 10(3) = 30

From the right, the limit is ...

  f'(x) = 2dx

  = 2d(3) = 6d

__

This gives us a pair of simultaneous equations in 'c' and 'd':

  45 +c = 9d -3

  6d = 30

The latter tells us d = 5. Then the former tells us ...

  45 +c = 9(5) -3   ⇒   c = -3

The function is differentiable if c = -3 and d = 5.

Additional comment

With these values, the function becomes ...

  [tex]f(x)=\begin{cases}5x^2-3&\text{if }x\le 3\\5x^2-3&\text{if }x>3\end{cases}[/tex]

Answer:

x= 1.36

Step-by-step explanation:

Answer:

Step-by-step explanation:

5(x−2 2/5) = −5.2

1. We need to use distibutaive property

5×x and 5×-2.4

5x - 12 = -5.2

2. We need to get x alone.

5x - 12 = -5.2

    -12      -12

5x = 6.8

3. We need to divide

5x = 6.8

/5     /5

x = 1. 36

check:

5(1.36−2 2/5)=−5.2

6.8 - 12 = 5.2

Answer:

I believe that y=7I'm not sure what your tring to figure out

Answer:

y=8/5x-4

Step-by-step explanation:

1:find the slope

[tex]\frac{4+4}{5-0} =\frac{8}{5}[/tex]

slope/m=8/5

2: solve for b using Y=mx+b

plug in the numbers to find b (the x and y get from one set of the points your given and the m is the slope)

Y=mx+b

y=4

m=8/5

x=5

4=8/5(5)+b

4=8+b

-4=b

than to put all the in y=mx+b form just plug in the b and m

Answer:

The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. Also known as the lowest common denominator

Your welcome

Judging by the image the function graphed has an asymptote at x = 3 and extends forever to -infinity along the x axis.

so the answer would be - infinity not included (because infinity is a concept not a number) to +3 not included because the function infinitely approaches x = 3. this is (-∞,3) in interval notation.

Answer:

196.2801

Step-by-step explanation:

a triangle adds up to 180 degrees, so if you add 81.66 and 84.33 together, it adds up to 165.99. if you subtract 180 and 165.99, you will get 14.01. Finally, you multiply 14.01 and 14.01 to get 196.2801. Hoped this helped!

Answer:

a) 17

b) 45

Step-by-step explanation:

a) [tex]9+3 x 2^{2} - 1 x 4[/tex]

use pemdas first,

[tex]2^{2}\\[/tex] = 4

3x4 = 12

1x4 = 4

now the equation is [tex]9+12 - 4[/tex]

9+12 = 21

that makes the equation 21-4

21-4 = 17

a) 17

now for b

b)

the equation would then be [tex]9+3 x (2^{2} - 1) x 4[/tex]

so youd use pemdas as always

start in the parenthases

[tex]2^{2}[/tex] = 4

4-1 = 3

the equation is now [tex]9+3 x 3 x 4[/tex]

now, multiply 3x3x4

3x3 = 9

9x4 = 36

now the equation is 9+36

9+36 is 45

b) 45

Answer:

8 Dollars for the hamburger and fry meal. then use the extra two dollars for a drink.

Step-by-step explanation:

[a] If the total is 450 and Gavin (g or y) earned 50 more than Seiji (s or x) then we can create the following system:

{ s + 50 = g

{ g + s = 450

[b] See attached

[c] Gavin earned $250 and Seiji earned $200

    Using the graph, we will look at where the points intercept. The x will be Seiji, and the y will be Gavin. Using this, we can see the answer is (200, 250) leaving Seiji with 200 dollars and Gavin with 250 dollars

    (there is also a simpler way to do this, but as I was following the assignment I think this is what you need!)

Have a nice day!

   Calculation example

1.multiply $55,000 by 0.5% (55,000 × 0.005) = $275.

2.multiply the amount exceeding $55,000 up to $250,000 by 1.0% (195,000 × 0.01) = $1,950.

3.multiply the amount exceeding $250,000 up to $400,000 by 1.5% (150,000 × 0.015) = $2,250.
