Answer:
Some 224 people were in favor of the expansion.
Step-by-step explanation:
Given that, according to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library, if 1004 people was polled, to determine how many were in favor of the expansion should be done the following calculation:
1/4 = 0.25
100 = 1004
22.25 = X
1004 x 22.25 / 100 = X
223.39 = X
Thus, some 224 people were in favor of the expansion.
First do 12-5, which equals 7. Next, subtract 1/10 from 2/5. 2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2. 4/10-1/10=3/10. Now add 7 and 3/10. You will get 7 3/10 as the answer, which is letter C.)
Answer:
14n-29
Step-by-step explanation:
Remove the unnecessary parenthesis around the (2n-9)
(2n-9)-5(-2.4n+4)
Distribute the -5 into the -2.4n+4
2n-9-5(2.4n+4)
2n-9+12n-20
Combine like terms
2n-9+12n-20
14n-9-20
14n-29
