Answer:
600 words
Step-by-step explanation:
To find how many words Jake can write in 20 minutes, you can find how many words he can write in 1 minute and multiply that by 20. Jake can write 30 words in a minute because 450 words divided by 15 minutes is 30. Then, multiply 30 by 20 which is 600.
We are given the equation:
0.6 x + 4.8 = 7.2
In this case, the multiplication property of equality states
that whatever is multiplied on one side should also be multiplied on the other
side. Now we need to find the number that will make everything a whole number,
in this case 5. Multiply everything by 5:
5 * (0.6 x + 4.8 = 7.2)
3 x + 24 = 36
However we can see that we can still further simplify the
equation by multiplying everything by 1/3:
(1/3) * (3 x + 24 = 36)
x + 8 = 12
or
x = 4
