C=300+1200x-100x. Find x if the total cost is 3,000
3,000 = 300 + 1200x -100x
3000 = 300 + 1100x
2700 = 1100x
2700÷1100=x
x=27/11
x = 2 5/11 Round to 3

Why do fractions need to have a common denominator before you add or subtract them?
djyliett [7]
Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number
Example - 2/8 is a fraction
                but 2 is not a fraction

frosja888 [35]

Answer:

Option c is correct !!

Step-by-step explanation:

[ Refer to the attachment ]

As y = mx + c is an equation to represent the straight line ; we equate the given line with this equation !!

Where m is slope of the line

and c is y intercept !!

We get , m = -3/2 and c = 4

Also, two perpendicular lines follows the equation :-

(m1)(m2) =  - 1

Answer:

CBD = 63 degrees

Step-by-step explanation:

To find CBD, we must first find the value of x. To do so, we use this equation since CBD and ABC equal 96 degrees:

(6x+27) + (7x-9) = 96
13x+18 = 96
13x+18-18 = 96-18
13x = 78
13x/13 = 78/13
x = 6

Now that we know the value of x, we factor it in to CBD to find its true value:

6x+27
6(6)+27
36+27
= 63 degrees

To check if this answer is correct, we can also find the value of ABC and see if the two values equal 96:

7x-9
7(6)-9
42-9
= 33 degrees

63 + 33 = 96

The answer is correct. CBD = 63 degrees and ABC = 33 degrees.
