Answer:

2/3 ÷ 1/12 = 8/1 = 8

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1/12 is 12/1) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step cancelling by a common factor of 3 gives 8/1.

Answer

Find out the how long will it take Jennifer to catch Jeff.

To prove

Formula

$Speed = \frac{Distance}{Time}$

let us assume that the distance be denoted by d .

let us assume that the time be denoted by t .

As given

Jeff is traveling from his home in Salem at a constant rate of 50 mph.

He has already traveled 20 miles .

As put the values in the formula

$50 = \frac{d + 20}{t}$

50t - 20 = d

(As jeff already travelled 20 miles distance.)

As given

His sister Jennifer is making the same trip but at a constant rate of 60 mph and has only traveled 5 miles.

than put the value in the formula

$60 = \frac{d +5}{t}$

than the equation becomes

60t -5 = d

Than the two equation becomes

50t - 20 = d and 60t -5 = d

compare both the equation

50t - 20 = 60t -5

50t - 60t = 20 -5

- 10t = 15

$t = \frac{-15}{10}$

t = -1.5

(As time cannot be negative.)

t = 1.5 hours

1.5 hours will it take Jennifer to catch Jeff.

Option (A) is correct .

Answer:

1. 1/x = 8

Answer = 8x-1

2. 8x+1=3

Answer ; x=1/4

3. 7= 14/X

Answer ; x = 2

4.1/2x^2 = 2

Answer ;x=2

Step-by-step explanation:

$\frac{1}{x} =8 \\8x = 1\\\\\\8x+1=3\\Collect -like- terms \\8x =3-1\\8x = 2\\Divide -both -sides- by ;8\\\frac{8x}{8} =\frac{2}{8} \\x = 1/4\\\\\\7= \frac{14}{x} \\Cross -multiply\\7x =14\\Divide-both-sides-by-7\\x = 2\\\\\\\frac{1}{2} x^{2} =2\\\frac{x^{2} }{2} =2\\Cross-multiply\\x^{2} =4\\Squre-root -both-sides\\\sqrt{x^2}=\sqrt{4} \\x = 2\\$
