Step-by-step explanation:
the solution to a system of functions (lines or any other form of curve) is the point (or points), where they intersect.
in this case : the point (2, 0)
FYI : if there is no intersection, then there is no solution at all (like with parallel lines).
if the curves fully overlap for at least some distance, then we have infinitely many solutions (at least for real numbers). like for identical lines.
The answer is T=PV/nR
Hope this helps!
Answer: d × 4 = D
Step-by-step explanation: d= days and D= dollars
Answer:
6) Option B) distributive property is correct
Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property
7) Option B) distributive property is correct
Therefore x+3(7-x)=x+21-3x are equivalent by using distributive property
Step-by-step explanation:
6) Given that the expressions 5+2(x-7) and 5+2x-14 are equivalent
To verify that the given expressions are equivalent by which property :
5+2(x-7)
=5+2(x)+2(-7) ( by using the distributive property a(x+y)=ax+ay )
=5+2x-14
Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property
Therefore option B) distributive property is correct
7) Given that the expressions x+3(7-x) and x+21-3x are equivalent
To verify that the given expressions are equivalent by which property :
x+3(7-x)
=x+3(7)+3(-x) ( by using the distributive property a(x+y)=ax+ay )
=x+21-3x
Therefore x+3(7-x)=x+21-3x are equivalent by using distributive property
Therefore option B) distributive property is correct
Answer:
The weight of watermelon at the end of the trip is <u>500 kg.</u>
Step-by-step explanation:
Given:
The weight of watermelons is 1000kg.
At the beginning of the trip watermelon is 99% of the weight:
99% of 1000kg


kg
Now, at the end of the trip it is 98% of weight. So, let
kg of water has been evaporated. So, remaining weight of the watermelon is
.
If
kg of water is removed, then the amount of water left is
.
As per question, water now weighs 98% of the total weight. So,
98% of (
) = 


(Bringing like terms on one side)

Therefore, the weight of watermelon at the end of the trip is given as:
Weight =
= 1000 - 500 = 500 kg
Therefore, the watermelon weighs 500 kg at the end of trip.
