Answer: hours
Step-by-step explanation:
Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.
As per given , we have
x+y= 8
Since :
So , we have
20x+12y=122
According to the given question , we have the following system of equations ,
Multiply 12 on both sides of equation (1) , we get
Eliminate equation (3) from (2) , we get
Hence, you felt hours good.
We have the equation xy-7y=49.
First, we factor out the common term for "y"
y(x - 7) = 49
Now, divide both sides by x - 7.
y = 49/x-7 <====
Answer:
5
Step-by-step explanation:
1) add the parenthesis (5+4)
2) You get 9
3) you take your next number (-4) and because the signs are different you subtract and take the sign of the higher number (9).
Given:
In △ABC and △PQR, AB = 5 cm , BC = 6 cm , AC = 8 cm , PQ = 6 cm , QR = 5 cm , PR = 8 cm.
To find:
The correct congruency statement for the given triangles.
Solution:
In △ABC and △PQR,
(Given)
(Given)
(Given)
All three corresponding sides of both triangles are equal. On comparing both triangle, it is conclude that the corresponding angles of A, B, C are R, Q, P respectively.
(SSS congruency postulate)
Therefore, the correct option is C.
Answer:
100°
Step-by-step explanation:
sum of two interior angles in a triangle that is not adjacent to exterior angle is equal to that exterior angles
so
x° + 50° = 150°
x = 100
