Answer:
x <= -51/5
First option
Step-by-step explanation:
GCM = 28
4(x-4) - 2(x+7) >= 7(x+3)
Distributive property
4x-16 -2x - 14 >= 7x + 21
2x - 30 >= 7x + 21
- 5x - 30 >= 21
-5x >= 51
x <= -51/5 (divide a negative number, flip the sign)
Answer
x <= -51/5
Answer:
(A) 2 3/10
(B) 1 7/15
Step-by-step explanation:
(A) Add the gallons he collected together to get the total amount of milk he started with: 4/5 + 6/8 + 3/4 = 2 3/10 gallons of milk.
(B) Take that number, 2 3/10, and subtract the amount of milk he has left to get the amount of milk he used. 2 3/10 - 5/6 = 1 7/15

Answer:
- boat: 72 km/h
- current: 16 km/h
Step-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.
