Answer:
Step-by-step explanation:
The photo for the question is not given. I have searched and attached it.
From the attached photo, the inequality is
-2x/3 + 9 > 7
By simplifying, subtract 9 from both sides of the inequality. It becomes
-2x/3 + 9 - 9 > 7 - 9
- 2x/3 > - 2
Multiplying both sides of the inequality by - 3/2, the inequality symbol would change due to the negative sign. It becomes
- 2x/3 × 3/2 < - 2 × - 3/2
x < 3
Therefore,
Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.

Answer:
The boat traveling at 24 kph when John goes downstream.
Step-by-step explanation:
We are given the following in the question:
John has a boat that will travel at the rate of 15 kph in still water.
Let x be the speed of the current.
Speed of boat in upstream
Speed of water in downstream
Relation:
We have to find the speed of boat in downstream.
Time to travel upstream for 35 km = Time to travel 140 km downstream
Thus, speed of current is 9 kph.
Speed of boat in downstream = 15 + 9 = 24 kph.
Thus, the boat traveling at 24 kph when John goes downstream.
