Sarah rolled a one 3 times and rolled a three 1 time in a total of 20 rolls. She rolled one or three 4 times out of 20. Therefore,
The answer is A.
The answer is A.
To the nearest tenth the value of x that satisfies 2x = −2x + 11 is
1 answer:
To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is
.
Let's perform step 1: reducing one side to variables only. By adding
to both sides of the equation, we get 
.
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of
is 
, we need to divide both sides of the equation by 4: 
. Rounded to the nearest tenth, 
.
So the value of
that satisfies is .
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
