30 minutes. the easiest way is to use the opposite of the fraction. divide 25 / 5= 5. now multiply by 6. 5*6= 30.
Answer:
Speed of Jet in Still Air = 265 miles per hour
Speed of Wind = 22 miles per hour
Step-by-step explanation:
Let x be speed of jet
and c be speed of wind
We know D = RT, where
D is distance
R is rate
T is time
For first leg:
1435 miles in 5 hours, the rate is:
Rate = 287 mph
For second leg:
1215 miles in 5 hours, the rate is:
Rate = 243 mph
So 287 is with wind and 243 against wind, thus we can write:
x + c = 287
x - c = 243
Adding gives us:
2x = 530
x = 265 miles per hour [still rate]
Speed of wind:
x + c = 287
265 + c = 287
c = 22 miles per hour [speed of wind]

divide 65 by 5 to get 13
Answer:
147
Step-by-step explanation:
E = greatest common factor of 22 and 30 = 2
F = least common multiple of 3 and 8 = 24
G = 3 * (7 + 10) = G + 30 = 81
3 * 7 + 3 * 10 = G + 30
21 + 30 = G + 30
51 = G + 30
G = 81
H = 5 * (3 + H) = 15 + 45 = 40
5 * 3 + 5 * H = 15 + 45
15 + 5 * H = 60
20 * H = 60
H = 60 - 20
H = 40
E = 2 + F = 24 + G = 81 + H = 40
2 + 24 + 81 + 40 = 147
This was fun lol
Answer :y=−1
Step-by-step explanation:
y2+2y+1=0
Step 1: Factor left side of equation.
(y+1)(y+1)=0
Step 2: Set factors equal to 0.
y+1=0 or y+1=0
y=−1
