So, 2x + 4x, is added to get 6x, because they are like terms, because they both have the same variable. Then, we subtract 4y-2y= 2y. Then the answer would be 6x plus 2y.
(Note: when you simply like therms they need to have the same variable to same power if they are addition of subtraction. Also, a term includes the negative or positive sign. And when all the work is finished and you need to put together your answer, always add, unless one of them is negative)

Steps:

=(2x+4x)+(4y-2y)
=6x+2y

You add your x's 2+4= 6x and do the same with your y's 4-2= 2y you do with with ONLY X's with X's and Y's with Y's bc they are like terms

6x+2y should be your answer

Find the value of x and y.

Leya [2.2K]

Answer:

x = 63 y = 27

Step-by-step explanation:

The straight line is 180 degrees

subtract 117 from 180 to get 63

It says x+7= 90, so subtract x(63) from 90 to get 27

Why is the number of operators per shift multiplied by approximately 4.5 to obtain the total number of operators required to run

4vir4ik [10]

I believe you meant "why is the number of shifts multiplied by approximately 4.5 to obtain the total number of operators required to run the plant"

Answer and Explanation:

There are 3 shifts per day, 49 weeks per year and 5 shifts per operator per week

To get total number of operators required to run the plant, we multiply number of shifts in a year by number if operators per shift.

49 weeks×5 shifts= 245 shifts per operator per year

365×3 shifts= 1095 shifts per year

1095/245=4.5 operators per shift

total number of operators required to run the plant(per day) = 4.5×3= 13.5 approximately 14

total number of operators required to run the plant(per year) =4.5×1095=4927.5 approximately 4928

What are the potential solutions of In(x2 - 25) = 0?

Paha777 [63]

Answer:

$x=\pm\sqrt{26}$

Step-by-step explanation:

$ln(x^2-25)=0$

$e^{ln(x^2-25)}=e^0$

$x^2-25=1$

$x^2=26$

$x=\pm\sqrt{26}$

What is 575% written as a mixed number?

pav-90 [236]

Answer:

575% as a mixed number is $5\frac{3}{4}$

Explanation:

575% is equivalent to $\frac{575}{100}$ which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as $\frac{75}{100}$ . This value can be simplified by dividing both the numerator and the denominator by 25. This would give us $\frac{3}{4}$

Back to our number:

$5.75 = 5 + 0.75 = 5 + \frac{75}{100} = 5 + \frac{3}{4} = 5\frac{3}{4}$

Hope this helps :)
