Answer:
-2x - 6
Step-by-step explanation:
Multiplication must be done before addition or subtraction. Thus, we leave '4' as is and multiply out -2(x + 5), obtaining:
4 - 2x - 10, or -2x - 6
Answer:
4√5
Step-by-step explanation:
2√5 + 3√5 - √5 = 4√5
add up 2 and 3 that's in front of √5 then subtract 1 from it
Answer:
1 s / 6 s
Step-by-step explanation:
Since you have different units of measurement (seconds and minutes) you have to get them to be the same unit.
Change the 1 minute into seconds.
1 min = 60 sec
Now simplify the new fraction.
10 s / 60 s
10 can go into both the numerator and the denominator.
1 s / 6 s
Number of raptors in 2015: 234
% success: between 35% and 40%
Formula
% =: [number of success rescues / number of total rescues] * 100 =>
number of success rescues = % * number of total rescuess / 100
Number of success rescues:
a) 35 * 234 / 100 = 0.35 * 234 = 81.9
b) 40 * 234 / 100 = 0.40 * 234 = 93.6
Then, the number of raptor rescues that were succesfull was about 82 to 94.
