Answer:

1/28^2

7^-2/ 4^2

Step-by-step explanation:

We know that a^b * c^b = (ac)^b

4^-2 * 7^-2

(4*7)^-2

28 ^ -2

We know that a^-b = 1/a ^b

1/28^2

We can also leave it as

4^-2 * 7^-2

1/ 4^2 * 7^-2

7^-2/ 4^2

Two runners live 33 miles apart. jim runs 8 miles per hour, and joan runs 6 miles per hour. if joan starts running toward jim's

salantis [7]

Let x be equal to Jim's travel time
Let x + 2 be equal to Joan's travel time
distance = speed*travel time
6(x + 2) + 8x = 33
6x + 12 + 8x = 33
14x = 21
x = 21/14 = 3.5

3.5 hrs is the hours that Jim have been running until he met Joan.

What is the product of 9/20 - 1/4

wlad13 [49]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

$\frac{9}{20} - \frac{1}{4}$

Make sure they have a common denominator. To do so, you must find a number the both have in come. Here, the number they have in common is 20.

What times 4 equals 20? 5. Whatever you do to the denominator you must do to the numerator.

$\frac{5}{5}$ × $\frac{1}{4}$ = $\frac{5}{20}$

Now you have $\frac{9}{20} - \frac{5}{20}$ = $\frac{4}{20}$

Then you can simplify $\frac{4}{20}$ to $\frac{1}{5}$ by dividing it by $\frac{4}{4}$
