Answer:
X= 12
Step-by-step explanation:
Simplifying
4x + -2 = 46
Reorder the terms:
-2 + 4x = 46
Solving
-2 + 4x = 46
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 4x = 46 + 2
Combine like terms: -2 + 2 = 0
0 + 4x = 46 + 2
4x = 46 + 2
Combine like terms: 46 + 2 = 48
4x = 48
Divide each side by '4'.
x = 12
Simplifying
x = 12

Answer:
100
Step-by-step explanation:
To find mean/average you add all of them together, then divide by however number there are.
So
99+88+97+107+100+109 = 600/6 = 100
altogether there are 7 marbles in the bag.
put the marbles in fractions, so blue would be 3/7
and red would be 4/7. but becuase you need 2 of the same, you do
3/7 x 3/7 = 9/49
4/7 x 4/7 = 16/49
then add them togther
25/49
if you need it as a percentage, it is
51.020408163265%
