First you have to make the units same. it will be easier if you make both the units to be days.
2 weeks= 14days
ratio will be
34:14
if you can make it into simpler form, then make it. this answer can simplified into smaller form,thus,
34:14
17:7
the answer is 17:7
Answer:
the first one
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
1/4 + 1/6 = (6+4)/24 = 10/24 = 5/12
why +1/6?
because: - (-) = +
Nice so
remember
t=d/s
a(b+c)=ab+ac
time=distance/speed
lets say s=jamie's normal speed
speed agains wind=s-4
speed with wind=s+4
30 miles is agains wind
distance is 54 with wind
t=d/s
t=30/(s-4)
t=54/(s+4)
since they are both equal to t, set them equal to each other
30/(s-4)=54/(s+4)
multipliy both sides by (s+4)(s-4)
30(s+4)=54(s-4)
distribute
30s+120=54s-216
subtract 30s from both sides
120=24s-216
add 216 to both sides
336=24s
divide both sides by 24
14=s
answer is 14 miles per hour without wind
Answer:
x = 13
Step-by-step explanation:
Sum or interior angles of a triangle is 180,
6x + 19 + 5x - 15 + 3x - 6 = 180
6x + 5x + 3x + 19 - 15 - 6 = 180
14x + 19 - 21 = 180
14x - 2 = 180
14x = 180 + 2
14x = 182
x = 182 / 14
x = 13
