I suppose you want to solve the following equation for b:
First of all, you need to divide both sides by 9:
Then, subtract 2 from both sides:
Answer:
$1.25
Step-by-step explanation:
The graph shows that 3 pens cost $3.75 which means each pen costs more than $1 so we know that the greater number will be the numerator in our division equation. Divide 3.75 by 3 to get the unit rate.
3.75/3=1.25
Each pen costs 1.25
You can check your work by plugging it into the other points.
6*1.25=7.5 -So that second point is correct
9*1.25=11.25- The third point is also correct meaning we got the right answer
Answer:
x = 1/4
Step-by-step explanation:
I think they are equivalent
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333
Simplifying
x = 0.3333333333
