X=3 is the answer
Solution- Divide both the sides by 7 and that will get you x+4=7 next move the constant to the right hand side and change the sign so it will be x=7-4 and then you just subtract the numbers and it will equal 3 so x=3 Is Your Answer
Answer:
4
Step-by-step explanation:
Use the first equation cause -2 < -1
-2(-2) = 4
The equation is given as W varies directly with u and inversely with d, then the equation is written as:
W = k1u
here k2 is the proportionality constant.
and p = k2

here k2 is the proportionality constant.
Thus, combining both equations we get, p = K

where K = K1*K2, is the proportionality constant.
