Answer:
x = 15
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ KLM is an external angle of the triangle, thus
∠ KLM = ∠ JKL + ∠ KJL , substitute values
5x - 7 = x + 20 + 2x + 3
5x - 7 = 3x + 23 ( subtract 3x from both sides )
2x - 7 = 23 ( add 7 to both sides )
2x = 30 ( divide both sides by 2 )
x = 15
The answer is D. An agreement from everyone on the collaborative team to share equally in the work load.
Lets suppose his initial weight was 60 kilograms
A gain of 20% would make his new eight 60 + 20*60/100
= 60 + 12
= 72 kg
he lost 25% of this:-
= 72 - 25 * 72/100 = 54 kg
This = (54/60) * 100 = 90% of his beginning weight Answer
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.
