Noah spent 25 hours working on his car. he spent 4/5 of his time working on the transmission. how much time did noah spend working on the transmission.

Step-by-step explanation:

Explanation:

To solve this problem, you have to set up a proportion.

x

25

=

4

5

In this problem  

x

is how any hours Noah spent on transmission.

To find  

x

you have to cross multiply.

x

⋅

5

=

5

x

25

⋅

4

=

100

Now, you have to divide the product of the constants constants that don't have a variable (

24

and  

4

) by  

5

to find  

x

.

100

÷

5

=

20

Our final answer for  

x

is  

20

.

Noah spent a total of  

20

hours, or  

4

5

of his  

25

hours, working on transmission.

I hope this helps (:

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
