X - number of pens
y - number of stickers
{x + y = 5,000
{0.23x + 0.14y = 970
{x = 5,000 - y
{0.23(5,000 - y) + 0.14y = 970
{x = 5,000 - y
{1,150 - 0.23y + 0.14y = 970
{x = 5,000 - y
{-0.09y = -180
{x = 5,000 - y
{y = 2,000
{y = 2,000
{x = 3,000

Answer:
A=2(wl+hl+hw)=2·(9·12+3·12+3·9)=342
Step-by-step explanation:
Answer:
Probability = 0.6
Step-by-step explanation:
We are given that out of 6 employees, 3 have been with the company for five or more years which means remaining 3 employees have been with the company for less than 5 years.
We have to find the probability that If 4 employees are chosen randomly from the group of 6, what is the probability that exactly 2 will have five or more years seniority;
This means that 2 employees will be selected from the group of 3 employees who are with the company for five or more years and remaining 2 employees will be selected from the group of 3 employees who have been with the company for less than 5 years.
Number of ways in which exactly 2 will have five or more years seniority
=
Total number of ways for selecting 4 employees from group of 6 =
So, required probability = = { }
= = = 0.6
Distribute both numbers from the outside of the parenthesis and multiply that by the the number inside the parenthesis. So 1/2(4x+13) means that you have to multiply 1/2 by 4 and 1/2 by 13. 2x+6.5=6(x+7). On the other side, 6(x+7) do the same thing multiply 6 by x and 6 by 7. 2x+6.5=6x+42 Now thats done, move the "like terms" on the same side. So 2x will move to the other side of the equation while 42 will move the other side of the equation. 4x= -35.5 now divide -35.5 by 4 to find x. -8.875 is what x equals. I hope this helps you! You can also check if the x your found was correct.
