Cara's brother is 7 years old.
14 is twice as much as 7 (7 * 2 = 14).
Answer: im not sure
Step-by-step explanation:
-7=z/2+1
What you first need to do is to multiply both sides of the equation by 2
-14=z+2
Now you move the variable to the left side and change within it’s own sign
-z-14=2
Into
-z=2+14
Now you then add the numbers
-z=16
The last part you do is change the sign on both sides in this equation
z=-16
Therefore, z=-16 is your answer in number 16.
Simplify. Combine like terms
12x - 9x = 3x
7 - 15 = -8
3x - 8 is your answer
hope this helps
‘1 2 4 8 16’
my thinking is the numbers are squared.
