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:

Step-by-step explanation:
42/60= 0.7 = 7/10 = 70%
Answer:
20 degrees
Step-by-step explanation:
100+4x=180
4x=80
x=20
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
