I di not understand these any help greatly appreciated thank you
Rzqust [24]

Answer:

Step-by-step explanation:

First you need to convert it to a linear expression.

3x - y = 4

+3x        +3x

-1y = 3x + 4

---  ----- -----

-1     -1    -1

y = -3x -4

6x - 2y = 7

-6x         -6x

-2y = -6x + 7

----    -----   -----

-2       -2     -2

y = 3x - 3.5

-3x - 4 = 3x - 3.5

+3x         +3x

-4 = 6x - 3.5

+3.5       +3.5

-0.5 = 6x

-----   -----

6         6

-0.5

------ =  x

6

Katy chose a card at random from a deck of 52 cards. Katy replaced the first card and then chose a second card. What is the prob
Alisiya [41]
52 total cards....13 total diamonds in the deck

P(1st card picked being a diamond) = 13/52
replacing the card, so the sample space remains the same
P(2nd card being a diamond) = 13/52

P(both) = 13/52 * 13/52 = 169/2704 = 1/16 <==

A person can do a job in 6 days. Another can do the same job in 4 days. If they work together, how long do they need to finish t
stepan [7]

Answer:

5 days

Step-by-step explanation:

This would have to do with average. So if one does it in 6 days and the other does it in 4 days, you would do the number between them. So 5 is between 4 and 6.

The more complicated way of thinking of it is like this...

add 6 and 4           6+4     that  would  =   10

Because we added two numbers, we have to divide by two.

10/2      which equals 5.

If it was numbers closer together like. 6 and 7 the middle numbeR would be 6.5 for example.

I hope this helped!!
