Will mark brainliest, summer is on the line

common d=30

9/10 is less than (<) 14/15

Step-by-step explanation:

10 and 15 both go into 30 which would be the lowest common d.

so

9/10 is 27/30 (i times by 3 cos u had to get 10 to 30)

14/15 is 28/30 (i times by 2 cos u had to get 15 to 30)

28 is bigger than 27

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
