Answer:
and 
Step-by-step explanation:
-equation 1
-equation 2
Solving the equation 1 to get the value of
To solve such type of equations that have two unknown variables, find the value of one variable in terms of the other from any one of the equation and put the value in the second equation which will give the value of both the variables
Solving Equation 2 to find x


equation 3
Putting this value of x in the equation 1





, 
Putting the value of y in equation 3 to find the value of x


Answer :
5(x-6)(x-2)
= 5 [ x^2 -2x -6x +12 ]
= 5 (x^2 -8x +12)
= 5x^2 -40x +60
Answer:
21 grapes.
Step-by-step explanation:
We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.
First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.


Now, we will find half of 6 to find number of grapes eaten by Lucy.




Therefore, the three of them eat 21 grapes in all.
