His friend tub was 48 ounces and Francisco was .75 of 48. So, 48x 0.75 = 38.6
For the equation -1/2x+3y=-3
the x-intercept=6
the y-intercept=-1
So volume of a cube=edge legnth cubed so take the cube root of 1000 and get 10
the side legnth is 10 feet
If it is directly proportional, then:
m = kx
10 = k x -4
k = -2.5
m = 3 x -2.5
m= 7.5
Hope I helped!
