solve The greatest mass which can be supported by a beam of given thickness varies directly as the breath and inversely as the length. if a beam of breath 4cm and length 30m can be support a mass of 400kg, find the mass which can be supported by a beam 6cm broad and 40m long

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

14

step-by-step explanation:

14 x 3 = 42
