What is the value of w?

2/5 (w+5) = 4/5

-3

Step-by-step explanation:

2/5(w+5)=4/5

multiply 2 with w, and 2 with 5

2w/5+10/5=4/5

(2w+10)/5=4/5

cross multiply 4 with 5 and 5 with 2w+10

5(2w+10)=20

10w+50=20

10w=20-50

10w=-30

w=-30/10

w=-3

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
