What you want to do is found a common denominator which is 20, so you would multiply 7/4 times 5 and 8/5 times 4. So it would be 35/20-32/20 and the answer is 3/20.

476 divide by 17 using partial quotient
Temka [501]

Answer:

Perform the following division using partial quotients: 476 ÷ 17:

To reduce the numerator, we will be multiplying the denominator by factors of 10, 5, 2, and 1

1 7| 4 7 6

| 3 4 0|20 <---- 20 x 17 = 340

| 1 3 6 <---- 476 - 340 = 136

1 7| 4 7 6

| 3 4 0| 20

| 1 3 6|

| 8 5 | 5 <---- 5 x 17 = 85

| 5 1 <---- 136 - 85 = 51

1 7 |4 7 6

3 4 0 20

1 3 6

8 5 5

5 1

3 4 2 <---- 2 x 17 = 34

1 7 <---- 51 - 34 = 17

1 7 |4 7 6

3 4 0 |20

1 3 6

8 5 |5

5 1

3 4 |2

1 7

1 7 |1 <---- 1 x 17 = 17

0 <---- 17 - 17 = 0

Our partial quotients add up as follows:

20 + 5 + 2 + 1 = 28

Show solving steps for x^2-10x +4=12
Nadya [2.5K]

Answer:

Step-by-step explanation:

We are given

x^2 - 10x + 4 = 12\\

get it all to one side equaling zero

x^2 - 10x - 8 = 0

now, we want to find the factors of 8 that either add up to of have a difference of 10

Factors of 8:

1, 8, 2, 4

None of the factor pairs add up to or have a difference of 10.

So, we can use the quadratic formula

x = \frac{-b\pm\sqrt{b^2-4ac}  }{2a} \\x = \frac{10\pm\sqrt{100-4*8}  }{2}\\x =  \frac{10\pm\sqrt{132}  }{2}\\\\\\x = \frac{10 + \sqrt{132}  }{2}= 10.74456265\\x = \frac{10 - \sqrt{132}  }{2} = -0.7445626465
