What is the answer to 16-2t=t+9+4t

Oliga [24]

Answer:

t=1

Step-by-step explanation:

16-2t=t+9+4t

Combine like term

16-2t = 5t+9

Add 2t to each side

16-2t +2t= 5t+2t+9

16 = 7t+9

Subtract 9 from each side

16-9 = 7t+9-9

7 = 7t

Divide each side by 7

7/7 = 7t/7

1=t

Jennifer is leasing a car from a local auto retailer. The terms of the lease include a 9% interest rate for 36 months with a res

katrin [286]

1. The problem gives the residual value in percentage, and you need it in dollars. So, if the MSRP for the car Jennifer is leasing is $ 17,500, you have:

57%/100=0.57

residual value=$17,500*0.57= $9,975

2. Then, you need to substract the residual value and the lease term, to calculate the value of the car, as below:

car value=$17,500-$9,975=$7,525

3. You need to calculate the money factor, which is the interest rate divided by 2400. Then, you have:

Interest rate=9%/100=0.09

Money factor=0.09x2400
Money factor=0.00375

4. The interest is:

I=($17,500+$9,975)(0.00375)
I=$103.03

5. Therefore, the monthly payment is:

Monthly payment=(car value/36 months)+Interest
Monthly payment=($7,525/36)+$103.03
Monthly payment=$209.02+$103.03
Monthly payment=$312.06

What will Jennifer’s monthly lease payment be?

The answer is: d. $312.06

Which of these choices show a pair of equivalent expressions? Check all that apply.

The main rule we use in this exercise is

$( \sqrt{a} ) ^{m} =( a^{ \frac{1}{2}} )^{m} = a^{ \frac{1}{2}*m}=a^{ \frac{m}{2}}$

and the more general case:

$( \sqrt[n]{a} ) ^{m} =( a^{ \frac{1}{n}} )^{m} = a^{ \frac{1}{n}*m}=a^{ \frac{m}{n}}$
Using these rules, we make all the indices, or exponents, look like $a^{ \frac{m}{n}}$ , and compare them to each other.

A. $( \sqrt{8} )^{9} = ( 8^{ \frac{1}{2}} )^{9} = 8^{ \frac{1}{2}*9}= 8^{ \frac{9}{2}}$

B. $( \sqrt{4} ) ^{5} =( 4^{ \frac{1}{2}} )^{5} = 4^{ \frac{1}{2}*5}=4^{ \frac{5}{2}}$

C. $( \sqrt[3]{125} ) ^{7} =( 125^{ \frac{1}{3}} )^{7} = 125^{ \frac{1}{3}*7}= 125^{ \frac{7}{3}}$

D. $( \sqrt{12} ) ^{7} =( 12^{ \frac{1}{2}} )^{7} = 12^{ \frac{1}{2}*7}=12^{ \frac{7}{2}}$
