The answer is C
You can ignore the parenthesis so you have
<span>x + 50 + x + 30 + x + 50 + x + 30 (combine like terms)
4x+160 (factor out the 4)
4(x+40)</span>
Answer:
Step-by-step explanation:
Simplifying
2x + 13 = 0
Reorder the terms:
13 + 2x = 0
Solving
13 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 2x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 2x = 0 + -13
2x = 0 + -13
Combine like terms: 0 + -13 = -13
2x = -13
Divide each side by '2'.
x = -6.5
Simplifying
x = -6.5
Answer:
9.75
Step-by-step explanation:
6.5= 20% of 32.50
32.50+6.5= 39
39/4 = 9.75
Okay, so let's make a sample space where in one section, one toy is the leader of each group for as many possibilities as there are.
T K E
T E K
K E T
K T E
E T K
E K T
There are 6 possibilities, and so each arrangement has a 1 over 6 chance of being used.
