If x = 4, what does y equal?
x = 4 y = ?
9x = 2y

18

Step-by-step explanation:

We know x = 4, so just substitute this value into the equation to find y:

9x = 2y  ⇒  9 * 4 = 2y  ⇒  36 = 2y  ⇒  y = 36/2 = 18

Thus, y = 18.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
