x = 158/15
Step-by-step explanation:
It took me awhile to solve it, but I hope I got the correct answer and managed to help you ÷)
Step-by-step explanation:
-7(1+3x) = 4 + 5x
-7 - 21x = 4 + 5x
(get all the variables on one side. Don't forget to change the signs)
-7-4 = 5x + 21x
-11 = 26x
(divide both sides by the coefficient [26])
26x/26= -11/26
x = -11/26
Answer:
So, you need 3 days approximately
Step-by-step explanation:
We will use Chain Rule to solve this question.
According to Chain Rule, the work efficiency remains constant.
• WWF×TWWF×T= Constant
• Here W = Work Done, WF = Workforce, T = Time.
Let the number of days needed be 'x'.
Applying Chain Rule,
10×9×6= 15×12×(x)
Or, x=3x=3 day
So, you need 3 days approximately.

It is the first one ...w= 3z+2
Since it’s in percents, put the percent over 100 as a fraction and simplify them. For percents that aren’t given, add the rest and subtract it from 100 and then place it as a fraction over 100
