Answer:
74 and 27
Step-by-step explanation:
let x and y be the numbers
x + y =101........eqn 1
x - y = 47.......eqn 2
solve simultaneously
from equation 2, make x the subject
x= 47 + y........eqn 3
put eqn 3 into eqn 1
(47+y) + y = 101
47 + 2y = 101
2y= 101 - 47
2y=54
y= 54/2
y= 27
put y=27 into eqn 3
x = 47 + 27
x = 74
Answer:
225 words
Step-by-step explanation:
In order to find the answer to this question we have to find how many words she writes in 1 minute. To do this you need to divide 90 words by 4 minutes:
(90)/4 = 22.5 words/minute
Now that the words per minute is found, we can multiply it by the 10 minutes to find how many words she can write in 10 minutes:
(22.5)(10) = 225
Therefore, Sara can type about 225 words in 10 minutes.
