To Find:
2w=?
Solution:
Answer:
45%
Step-by-step explanation:
12,500-8,000= 4500
move the decimal 2 times to the left
(f+g)(x)=f(x)+g(x)
=-3x-5+4x-2
=x-7.Ans,,
Total work amount
6 men * 14 days
84 men days
If it is done within 21 days, need x men
84 men days = x men * 21 days
x = 84/21 men
x = 4 men
2r-3r+10=20
Move all terms to the left:
2r-3r+10-(20)=0
add all the numbers together, and all the variables
-1r-10=0
move all terms containing r to the left, all other terms to the right
-r=10
r=10/-1
r=-10
