Let us convert both speeds to meters per minute.
The turtle:
27 km/ hr
1000 m in a kilometer
60 minutes in an hour
(27*1000)/60
= 450 m/min
The girl:
14 dm/ s
0.1 m in a dm
1/60 minutes in a second
(14*0.1)/(1/60)
= 84 m/min
The turtle is
450 - 84
= 366 m/min faster than the girl
Basically, this is saying that 80% of (x) = 2 so you have know what the whole would be. It would be 2.5 because 80% of 2.5 is 2. So because you are subtracting 7 from v to get 2.5, you have to add 2.5 to 7 to get v. V=9.5
Answer:
if you are asking (2m - 10m + 5) + (8m +2), the answer would end up just being 7.
Step-by-step explanation:
simplify, 2m-10m = -8m.
5 + 2 = 7
-8m + 8m = (they cross each other out. you can't have a 0m)
Your Answer = 7
Answer:
The sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
we have
Let
p -----> the number
we know that
The numerator is (3p+6)
The phrase that represent this algebraic expression is "The sum of three times a number plus six"
The denominator is (7p-9)
The phrase that represent this algebraic expression is "The difference of seven times the number and nine"
therefore
The phrase that represent this problem is "The sum of three times a number and six, divided by the difference of seven times the number and nine"
