Answer:
x = 600 pages
Step-by-step explanation:
Let the total books pages be x
Given that
Hank had read = 25% of x
25% of x = 150
=>
Multiplying both sides by 4
=> x = 150 * 4
=> x = 600 pages

There you go.
Answer:
- 21 hours in May, 63 hours in June
Step-by-step explanation:
<h3>Set up equations</h3>
<h3>Solve by substitution, fin the value of j</h3>
- 1/3j + j = 84
- 4/3j = 84
- j = 84*3/4
- j = 63
<h3>Find m</h3>
- m + 63 = 84
- m = 84 - 63
- m = 21
Answer:
Boat = 20 mph
Current = 5 mph
Step-by-step explanation:
If b is the speed of the boat, and c is the speed of the current, then:
b + c = 225 / 9 = 25
b − c = 225 / 15 = 15
Solve the system of equations with elimination.
2b = 40
b = 20
Plug back into either equation to find the speed of the current.
c = 5
