Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
Answer:
24
Step-by-step explanation:
To solve the equation, multiply 60 by 2/5.
[Note: 60 can be written as 60/1]
60/1 x 2/5
Multiply the numerators:
60 x 2 = 120
Multiply the denominators:
1 x 5 = 5
Now simplify:
120/5 = 24
So, the correct answer is 24. I hope this helps! :)
Answer: 0.421
i can add the way to get the answer if you want too
88%, 44/50 is just 88/100. So 88% out of 100 of the coins are quarters.
Step-by-step explanation:
Recall that
so we can write our original equation as
or
Let 
so our equation becomes
which gives us two roots: 
and 
.
This is equivalent to 
and
