Answer:

1/10

Step-by-step explanation:

There are 5·4·3 = 60 ways to choose a 3-digit number from 5 digits (no repeats).

There re 1·2·3 = 6 ways to choose a number 5x2 or 5x4 from those digits.

The probability of randomly choosing one of 60 that is one of the 6 is ...

... 6/60 = 1/10

The product of two consecutive negative even integers is 24. Find the largest integer.
natali 33 [55]

-4

ok negative times negative = positive

and factors of 24 are

-4 x -6 = 24

If 2a+4b=5 and a is equal to three times b, what is 3a?
IrinaK [193]

Answer:

3a=4.5

Step-by-step explanation:

it says that "a is equal to 3 times b", which translates to a=3b

We can substitute a as 3b in 2a+4b=5

2(3b)+4b=5

multiply

6b+4b=5

add

10b=5

divide by 10

b=1/2

since it's given that a=3b, we can multiply 1/2 by 3

a=3/2

3a is 3 times a, so we can mutiply 3(3/2)=9/2=4.5

Hope this helps!
