13f + 6 -f = -3 <br><br> help?
malfutka [58]

Answer:

f = -3/4

Step-by-step explanation:

13f + 6 -f = -3

Combine like terms

12f +6 = -3

Subtract 6 from each side

12f+6-6 = -3-6

12f = -9

Divide each side by 12

12f/12 = -9/12

f = -3/4

Amount $100,000
sergey [27]

Answer:

1) Repaid for the loan = $239,511.60  

2) Percentage = 58.2%

3) Average amount = $387.53

Step-by-step explanation:

Given :

Amount $100,000  

Rate 7%

Payments 360  - $665.31

Total interest $139,511.60

To find :

1) How much will be repaid for this loan?

Repaid for the loan = Amount - Total interest  

Repaid for the loan = 100,000 + 139,511.60

Repaid for the loan = $239,511.60  

2) What percentage will be repaid for this loan?

\text{Percentage}=\frac{\text{Total interest}}{\text{Repaid loan}}\times100

\text{Percentage}=\frac{139511.60}{239511.60}\times100

\text{Percentage}=0.582\times100

\text{Percentage}=58.2\%

3) What will be the average amount per payment for interest?

\text{Average amount}=\frac{\text{Total interest}}{\text{Payments}}

\text{Average amount}=\frac{\text{139511.60}}{\text{360}}

\text{Average amount}=387.53

(07.05) Which of these is a simplified form of the equation 7x + 4 = 5 + 3x + 1x? (4 points) 3x = 9 3x = 1 11x = 9 11x = 1
slava [35]
Okay first you need to combine like terms together (3x and 1x)

7x + 4 = 5 + 4x

now you need x only on one side, you could subtract either 7x or 4x 

3x + 4 = 5

subtract 4 over

3x = 1 is the answer
