8 0

Answer:

The first step that you must do is multiple 1 (9) and add that product to 8. Do that same for 3 1/4. Your answer for both of these mixed fractions will be 17/9 x 13/4. There is nothing that can go into each other, then you just multiply the numerator and the denominator straight across. So you multiply 17 by 13 and 9 by 4. Your new fraction will be 221/36. Now if you do not have a calculator, you can try to find the prime factor of both the numerator and the denominator. The prime factors of 221 is 13 x 17 and for 36 = 2^2 x 3^2. Another solution is to find the Greatest Common Multiple of the two numbers to see what can divide into the both of them. For 221 the numbers are 13 and 17. The factors for 36 are 2, 3, 4, 6, 9, 12, 18. Or you can simply just divide 36 by 221. Your answer will be still be, however 6.14 as a decimal. As a whole number, your answer will be 6.

Solve each inequality.<br> X+5 < 6 <br> Pls help

agasfer [191]

Answer:

x<1

Step-by-step explanation:

You would just subtract 5 from both sides of the equation. The sign does not flip because you are not multiplying or dividing any negative number across the sign. So simply x+5 (-5) < 6 (-5). On the left side the 5 would cancel out. on the other side 6-5 is equal to 1.

Answer: x<1

-4x - 2 = -18 POR FA AYUDENME

charle [14.2K]

Answer:

The answer is x=4

Step-by-step explanation:

so you have -4x-2=-18

so we get rid of -2 by adding it to the other side so you'll end up having -4x=-16

you then divide that by -4 on both sides and get x=4 as your remaining answer

Owning a small and successful business isn't easy! There is a monthly cost of shipping supplies and

Answer:

$C(x)=24,000+19,200x$

Step-by-step explanation:

<u>Mathematical Modeling</u>

To model a real-life situation, a mathematical model can be constructed in such a way it accurately represents the variables measured in the system.

This problem requires to build a model for the yearly cost of a small and successful business.

The first data is the fixed monthly cost or the money the owner must pay regardless of the number of employees he hires. This cost includes shipping supplies and products for $2,000. To operate for a full year, the fixed cost is 12*$2,000=$24,000.

The other component of the cost function is the variable cost of x employees. Given each employee costs $1,600 each month, having x employees cost 1,600x each month. For a full year, the variable cost will be

12*1,600x=19,200x.

We finally form the total cost function:

$\boxed{C(x)=24,000+19,200x}$

Help how can I Write the given standard equation of the quadratic in intercept form

olya-2409 [2.1K]

Answer:

f(x) = (x - 10) (x + 10)

Step-by-step explanation:

The equation looks like the difference of squares so 5 and 20 are out

-10 x -10 = 100

-10 x 10 = - 100

so (x - 10) (x + 10)
