Answer:
The answer is 3.
Step-by-step explanation:
The equation would be: x = 14.95 divided by 4.99, rounded to the nearest one:
14.95 divided by 4.99 = 2.99599...
Normally, I would not round the number to the nearest digit in problems like these, but 2.99599 is quite close to 3, so this might be an exception.
Anyways, that's how I got my answer.
Hope this helped.
Answer:
RS = 10
Step-by-step explanation:
We are told that to get ∆QRS, the scale factor of ⅖ was used. To get side RS, we would multiply the side length of the side that corresponds to RS.
YZ corresponds to RS.
YZ = 25
Thus,
RS = 25*⅖
RS = 10
Answer:
3-pack= 135 cupcakes
6-pack= 270 cupcakes
9-pack= 405 cupcakes
Step-by-step explanation:
Let's say that 3-pack = a, 6-pack =b and 9-pack = c
The company’s leaders want to divide the cupcakes so that 3-pack, 6-pack and 9-pack packages produced are the same. This translate to an equation of:
a=b=c
The factory has 810 cupcakes in total. The equation will be:
a*3 + b*6 + c *9= 810
3a + 6b + 9c = 810
If we substitute the 1st equation into the second(we can put b=a and c=a), the equation will become
3a + 6b + 9c = 810
3a + 6(a) + 9(a) = 810
18a= 810
a=45
Using the first equation, we know that we have 45 packages of each kind.
If there are 45 packages of 3-pack, the number of cupcakes go into 3-package will be: 3*45= 135 cupcakes
If there are 45 packages of 6-pack, the number of cupcakes go into 6-package will be: 6*45= 270 cupcakes
If there are 45 packages of 9-pack, the number of cupcakes go into 9-package will be: 9*45= 405 cupcakes

Answer:
A Polynomial can be expressed in terms that only have positive integer exponents and the operations of addition, subtraction, and multiplication. In other words, it must be possible to write the expression without division.
Step-by-step explanation:
<em>EXAMPLES :</em>
- <em> x2 + 2x +5 Since all of the variables have integer exponents that are positive this is a polynomial.</em>
- <em>5x +1 Since all of the variables have integer exponents that are positive this is a polynomial.</em>
- <em>(x7 + 2x4 - 5) * 3x Since all of the variables have integer exponents that are positive this is a polynomial.</em>
- <em>5x-2 +1 Not a polynomial because a term has a negative exponent</em>
- <em>3x½ +2 Not a polynomial because a term has a fraction exponent</em>
- <em>(5x +1) ÷ (3x) Not a polynomial because of the division</em>
- <em>(6x2 +3x) ÷ (3x) Is actually a polynomial because it's possible to simplify this to 3x + 1 --which of course satisfies the requirements of a polynomial. (Remember the definition states that the expression 'can' be expressed using addition,subtraction, multiplication. So, if it's possible to simplify an expression into a form that uses only those operations and whose exponents are all positive integers...then you do indeed have a polynomial equation)
