First step=
we need to find time for i mile
which is
75/3000=1/40
then to find for 4000 miles we multiply that by 4000
which is 1/40x4000
cancel zeros
1/4x400
=100 hours for 4000 miles
Divide both sides by 4/5 or multiply by the reciprocal.
Flip 4/5 to get the reciprocal.
The reciprocal of 4/5 is 5/4 so we will multiply both sides by that.
5/4 * 8/9 = 4/5 * 5/4 * k
4/5 and 5/4 cancel out so now you have
5/4 * 8/9 = k
multiply top and bottom
(5 *8 )/(4*9)
40/36
Simplify
10/9
Answer:
a. k > 7
b. a < -21
c. h > 9
d. f < 301
Step-by-step explanation:
a. 2k + 7 > 21
2k > 14
k > 7
b. a/3 + 12 < 5
a/3 < -7
a < -21
c. 6h − 5 > 49
6h > 54
h > 9
d. f/7 − 9 < 34
f/7 < 43
f < 301
Hope this helps!
