Distance to the cabin is 'D' .
Distance = (speed) x (time)
Distance going = 30 H
Distance coming back = 36 (H - 1)
Distance is the same in both directions.
30H = 36(H - 1)
Eliminate parentheses: 30H = 36H - 36
Add 36 to each side: 30H + 36 = 36H
Subtract 30H from each side: 36 = 6H
Divide each side by 6 : 6 = H
It took 6 hours to go, 5 hours to come back,
and the trip was 180 miles each way.
6 x 30 = 180
5 x 36 = 180 yay !
Notice that 180 is the least common multiple (LCM)
of 30 and 36 . I'll bet that could have helped us if
we were all wide awake when we read the question.
Dale is 165 pounds
twice=330
divided by 3=110
Linda is 110 pounds
Step-by-step explanation:
30 minutes because you can just subtract Geoge's time
Cecilio tiene "x" años y Jonathan tiene "y" años.
Tres veces la edad de Cecilio es 3x y 3x es 48 años mas que "y".
3x = y + 48
Jonathan tiene un tercio de la edad the Cecilio.
y = x/3
3x = y + 48 se sustituye x/3 por y
3x = x/3 + 48
3x - x/3 = 48
9x/3 - x/3 = 48
8x/3 = 48
x = 48 * 3/8
x = 18
Cecilio tiene 18 años.
y = x/3 = 18/3 = 6
Jonathan tiene 6 años.
Answer:
21.25
Step-by-step explanation:
We can use the Pythagorean theorem to solve
We have the two legs and are looking for the hypotenuse
a^2 + b^2 = c^2
17^2 +12.75 ^2 = c^2 where c is the diagonal
289 +162.5625 = c^2
451.5625 = c^2
Take the square root
sqrt(451.5625) = sqrt(c^2)
21.25 =c
