Answer:
x = 3
Step-by-step explanation:
3(x−5)+4x−2=4
Step 1: Simplify both sides of the equation.
3(x−5)+4x−2=4
(3)(x)+(3)(−5)+4x+−2=4(Distribute)
3x+−15+4x+−2=4
(3x+4x)+(−15+−2)=4(Combine Like Terms)
7x+−17=4
7x−17=4
Step 2: Add 17 to both sides.
7x−17+17=4+17
7x=21
Step 3: Divide both sides by 7.
7x
7
=
21

The average speed can be obtained by the formula:

If a boat travels 36 miles in 1.5 hours ans then in 14 miles in 0.75 hour, then find:
- total distance is 36+14=50 miles;
- total time: 1.5+0.75=2.25 hours.
Therefore,
miles per hour.
Answer:
miles per hour.
