Answer:
Option B is correct.
The value of x is, 0
Step-by-step explanation:
Given the system of equation:
-x+2y =6 .....[1]
6y =x+18 ......[2]
We can write equation [1] as;
-x = 6-2y or
x = -6 + 2y ......[3]
Substitute equation [3] in [2] we get;
6y =-6 + 2y + 18
or
6y = 2y +12
Subtract 2y from both sides we get;
6y -2y = 2y+ 12 -2y
Simplify:
4y = 12
Divide both sides by 4 we get;
Simplify:
y =3
Substitute the value of y in equation [3] to solve for x;
x = -6 + 2(3)
x = -6 +6 = 0
Therefore, the value of x is, 0
Answer: Here we have a real life multiplication situation for which an estimate make sense:-
Miley has 212 fiction books. Sharon has 3 times fiction books has many as Miley has, how many fiction books Sharon has
Solution :- Number of fiction books Miley has = 212
Number of fiction books Sharon has= 3 times 212
We know that 212 is near to 200 , so round off 212 to 200 (to the nearest hundred)
Thus the product becomes
Therefore, the estimated number of fiction books Sharon has=600
