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.
Rational number is any number that can be shown as the quotient of two integers.
3x + 24 = (3)(x) + (3)(8)
You can see that there is multiplier 3 near x and 8. You can factor it and make
3x + 24 = 3(x + 8)
So, the answer is 3. Hope this helps!
Answer:
6.74
Step-by-step explanation:
To be able to do these equations, you draw a line down the middle of the equal sign to separate sides. So you are trying to get the variable (m) on one side by itself. In order to do that, you have to move 10.20 to the other side. But whenever you move things to the other side you have to do the opposite in this case it would be subtraction because 10.20 is a positive number but the opposite of positive is negative which means subtraction. So you do
3.46-10.20 which will give you -6.47 and now you have -m left but whenever u have a negative sign in front of a variable that means there is a one beside it. A number besides a variable is multiplication but the opposite is division so we would divide.
-6.47/-1 which is 6.47 :)
