If the product of two number is 10 and the sum is 7 ,then the longest of the two number is​
irinina [24]

Answer:

5 units

Step-by-step explanation:

Step one:

Given data

Le the first number be x

and the second number be y

So

x*y= 10-----------------1

and

x+y= 7-----------------2

from eqn 1

x= 10/y

put x= 10/y in eqn 2

10/y+y= 7\\\\10/y= 7-y

cross multiply we have

10=y(7-y)\\\\10=7y-y^2

rearrange

y^2-7y+10=0

the factors of the quadratic expression are

-5 and -2

y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\

The longest side is 5 units

Answer:

v= 3

Step-by-step explanation:

-19 + v = -8 ( v - 1 )

multiply -8(v - 1)= -8v + 8

-8v + 8v and then add the v with the +8v

Subtract -19 +19 and add the +19 with the +8= 27

27 divided by 9= 3

Is 5/6 less than 2/12
Ostrovityanka [42]
No, 5/6 is greater.

1) First, you have to get a common denominator, lets use 12
2) To get from 6 to 12 you would multiply times 2
3) Do the same to the numerator(the top number) which is to multiply 5 x 2
4) 5 x 2= 10 
5) So, now your fraction has become 10/12

And let me ask you, which is bigger, 10/12 or 2/12
(10/12 is bigger and 2/12 is less)
