Suppose y varies directly with x and y = 25 when x = 140. What is the value of x
when y = 36?

201.6

Step-by-step explanation:

y varies directly as x

y = kx... "k" is the constant

y = 25, x = 140

25÷140 =k × 140÷140

k = 0.17857

y = 0.17857 × x

when y = 36 what is x

36 = 0.17857 × x

x =36÷0.17857 =201.6

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✌✌✌
