Step-by-step explanation:
<h3><u>TO SOLVE:</u></h3>
Isolate by the x on one side of the equation.
<h3><u>SOLUTIONS:</u></h3>
First, subtract 3x from both sides.
![\displaystyle \Rightarrow \mathsf{3x+11-3x=3x-11-3x}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5CRightarrow%20%5Cmathsf%7B3x%2B11-3x%3D3x-11-3x%7D%7D)
Solve.
![\displaystyle \mathsf{11=-11}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cmathsf%7B11%3D-11%7D)
Sides are NOT equal.
![\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS}}}](https://tex.z-dn.net/?f=%5CLarge%5Cboxed%7B%5Cmathsf%7B%5CRightarrow%20THERE%20%5Cquad%20ARE%20%5Cquad%20NO%20%5Cquad%20SOLUTIONS%7D%7D%7D)
Therefore, there are no solutions.
Answer:
a. $1,617
b. $4,983
Step-by-step explanation:
a. The account suffered a decrease of 24.5% of the original sum of $6,600.
This amount in cash is:
= 24.5% * 6,600
= $1,617
b. If the account reduced by $1,617, the balance left is:
= 6,600 - 1,617
= $4,983
Since the shading on the left side, and the line goes through the x axis, your answer would be B.
Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6
