Pls help yall...im stuck on it

x =

Step-by-step explanation:

Given

= ( cross- multiply )

3x = 2 × = ( divide both sides by 3 )

x =

The number that goes in the green box is 7

Step-by-step explanation: The LHS of the equation can also be expressed as,

x/ (7/8) OR

x times (8/7)

That is, 8x/7

In other words, the equation now becomes;

8x/7 = 2/3

By cross multiplication we now have

8x(3) = 7(2)

24x = 14

Divide both sides of the equation by 24

x = 14/24

(Simplified further)

x = 7/12

Therefore the number that goes in the green box is 7.

i dont know

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
