Answer:
Finance charge = $1500
Step-by-step explanation:
Cost price of jukebox = $9400
Down payment made by a local diner = $1000
Balance amount to be paid = 9400 - 1000 = $8400
In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months
Total amount to be paid in 36 months = 275 × 36 = $9900
So extra payment done = Total balance amount - Amount paid in 36 installments
= 9900 - 8400
= $1500
Therefore, finance charge paid by the diner was $1500.
M<A + m<B = 180
5y + 9y + 68 = 180
14y + 68 = 180
14y = 180 -68
14y = 112
y = 112/14
y = 8
so
m<B = 9y + 68
m<B = 9(8) + 68
m<B = 72 + 68
m<B = 140
Answer:
x = -5/3, y = -1 or 
Step-by-step explanation:
Solving systems of linear equations using process of elimination involves eliminating one of the variables (and its coefficient) in order to solve the other variable either through addition or subtraction. However, there may be other mathematical operations necessary before one of the variables can be eliminated.
Equation 1: 3y - 6x = 7
Equation 2: -4y - 3x = 9
<h3>Step 1: Multiply Equation 2 by -2:</h3>
(-2)(-4y - 3x) = 9 (-2)
8y + 6x = -18
<h3>Step 2: Add "8y + 6x = -18" to Equation 1:</h3>
8y + 6x = -18
+ 3y - 6x = 7
11y = -11
<h3>Step 3: Divide both sides by 11 to solve for y:</h3>

y = -1
<h3>Step 4: Substitute y = -1 into Equation 2 to solve for x: </h3>
-4(-1) - 3x = 9
4 - 3x = 9
<h3>Step 5: Subtract 4 from both sides:</h3>
4 - 4 - 3x = 9 - 4
- 3x = 5
<h3>Step 6: Divide both sides by -3 to solve for x:</h3>


Verify whether the values for x and y are correct by substituting their values into both equations:
x = -5/3, y = -1
Equation 1: 3y - 6x = 7
-3 + 10 = 7
7 = 7 (True statement).
Equation 2: -4y - 3x = 9
-4(-1) - 3 (-5/3) = 9

4 + 5 = 9
9 = 9 (True statement).
Therefore, x = -5/3 and y = -1 are the solutions to the given systems of linear equations.
