Jobisdone [24]3 years ago
6 0

Answer:

None.

Step-by-step explanation:

5/a - 2 / (1 - a) = 2 (a - 1)

Multiply each term by  a(1 - a)(a - 1):

5 (1 - a)(a - 1) - 2a(a - 1)  = 2a(1 - a)

5( a - 1 - a^2 + a)  - 2a^2 + 2a = 2a - 2a^2

5(-a^2 +  2a  - 1) - 2a^2 + 2a = 2a - 2a^2

-5a^2 + 10a - 5 - 2a^2 + 2a - 2a + 2a^2 = 0

-5a^2 + 10a - 5 = 0

-5(a^2 - 2a + 1) = 0

= -5(a - 1)^2 = 0

So a = 1.

But a = 1 cannot be a root because 2/ 1 - a would be 2/0 which is undefined.

Also 2 / (a - 1) is undefined.

13. kara walks five days each week. this week she walked 7/8 mile on monday, 3/5 mile on tuesday, 4/10 on
BigorU [14]

The total distance, in miles, that kara walked at the park this week is 57/20.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that kara walks five days each week. this week she walked 7/8 mile on monday, 3/5 mile on tuesday, 4/10 on wednesday, 1/10 mile on thursday, and 9/10 mile on friday.

Now, in order to find the total distance, in miles, that kara walked at the park this week.

kara walked on Monday = 7/8

kara walked on Tuesday = 3/5

kara walked on wednesday = 4/10

kara walked on thursday=1/10

kara walked on friday= 9/10

Now, to get the total distance in miles by adding both the miles she walked this week:

7/8 + 3/5 +4/10 + 1/10 + 9/10

35/40 + 24 / 40 + 14/10

59/40 + 14/10

114/40

57/20

Therefore, the total distance, in miles, that kara walked at the park this week is 57/20.

neonofarm [45]

Given

Find out the  what was the insurance company's payment .  

To proof

As given

Sally Jones pays $50.00 a month for group health insurance

There is a $300 deductible

Her medical bills for the last year were $2,600.00

Linda's insurance company provided payment of 80% of the bills less the deductible.

Deductible

The  amount of money you will pay in an insurance claim before the insurance company starts paying you.

medical bill reducing the deductible = $2,600 -  $300

                                                             =  $2300

80 % is written in the decimal form

= \frac{80}{100}

= 0.8

than the equation becomes

Linda's insurance company provided payment  = 0.8× 2300

                                                                                = $1840

Therefore the the insurance company's payment be  $1840 .

Hence proved
