Answer:
the answer is 4 it think it is correct
3 yellow marbles + 2 blue marbles + x green marbles = 12 marbles
x green marbles = 12 marbles - 5 marbles
x green marbles = 7 green marbles
Isolate the G. Note the equal sign. What you do to one side, you do to the other.
Subtract 5 from both sides.
G + 5 = 33
G + 5 (-5) = 33 (-5)
G = 33 - 5
Simplify
G = 28
28 is your answer for G
Hope this helps
Answer:
2 and -2
Step-by-step explanation:
● 7q^2 -28 = 0
Add 28 to both sides
● 7q^2-28+28 = 28
● 7q^2 = 28
Divide both sides by 7
●7q^2/7 = 28/7
● q^2 = 4
You can write directly q= 2 or q= -2
To understand it use the absolute value.
● |q| = 2
● q = 2 or q = -2
The solutions are {2, -2}
