Suppose that y varies jointly with w and x and inversely with z and y= 120 when w= 5, x= 28 and z= 7. write the equation that models the relationship. then find y when w= 7, x=5 and z=3.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

answer:

125 yards

explanation:

75+50=125. that is my answer

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
