Musya8 [376]

Answer:

There are 2 red pens in each pack

There are 3 blue pens in each pack

Step-by-step explanation:

<u> we know that</u>

270=2*3^{3} *5

180=2^{2}*3^{2}*5

<u>Find the Greatest Common Factor (GCF)</u>

The GCF is equal to------> 2*3^{2}*5=90

the greatest number of packs she can make is 90

Find the number of red pens in each pack 180/90=2 red pens

Divide the total number of red pens by the total number of packs

Find the number of blue pens in each pack 270/90=3 blue pens

Divide the total number of blue pens by the total number of packs

Find the value t if the value of 3x + 5x – 2t equals to 8, when x = -1 .
Evgesh-ka [11]

Step-by-step explanation:

3x + 5x - 2t = 8

3 . (-1) + 5 . (-1) - 2t = 8

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
notka56 [123]

Answer:

30%

Step-by-step explanation:

The options are 3,4,5,6,7,8 for a total of 6 choices

odd number: 3,5,7 = 3 options

P (odd number) = number of options / total choices

                          =3/6

                           =1/2

Now we pull our odd choice out and keep it ( assume 3)

The options are ,4,5,6,7,8 for a total of 5 choices

even number: 4,6,8 = 3 options

P (even number) = number of options / total choices

                            = 3/5

P (odd, no replacement, even) = 1/2* 3/5 = 3/10

Changing to a percent = 30/100 = 30%
