Answer:
x = 1
Step-by-step explanation:
To find the solution to the equation given, we will follow the steps below:
2(3x-6)= -12+6
Open the bracket
6x - 12 = -12 + 6
6x - 12 =-6
Add 12 to both-side of the equation
6x -12 + 12 = -6 + 12
6x =6
Divide both-side of the equation by 6
6x/6 = 6/6
At the left-hand side of the equation, 6 will cancel-out 6 while at the right-hand side of the equation, 6 will be divided by 6
x = 1
I believe it is Since the square root of 9 = 3 and the square root of 16 = 4 it is known the the square root of 12 is in between 3 and 4. Really hope this helps!

Answer:
x = -1
Step-by-step explanation:
f() = 120, therefore we can create this equation:
120 = 150 ÷ ( - z)
cross-multiply to get: 24 - 120z = 150
-120z = 126
z = -1
Answer:
Cards with Mark = 30
Cards with Drew = 120
Cards with Katie = 12
Step-by-step explanation:
The complete question is
Drew has 4 times as many baseball cards as Mark. Katie has 3 fewer than than half as many cards as Mark. In all they have 162 baseball cards. How many does each have?
Solution -
Let the number of cards with Mark be "X"
Number of cards with Drew = 4 *X = 4X
Number of Cards with Katies = 0.5 X -3
Sum of all the cards is equal to 162
X+4X + 0.5 X -3 = 162
5.5 X = 165
X = 30
Cards with Mark = 30
Cards with Drew = 4 * 30 = 120
Cards with Katei = 15-3 = 12
