No. 1a and 3d are linear, but 2bc is not. ■
Call the unknown value of (x - y) d. Then x = y + d; from the problem statement, y + d + 2(y + d) +5 = y + 2y; expanding yields y + d + 2y + 2d + 5 = y + 2y; (y + 2 y) can be subtracted from both sides and terms in d collected to result in 3d + 5 = 0; 3d = -5; d = -5/3.
Some 3D shapes are cones, cubes, pyramids, and cylinders.
Its main application is in finding the volumes of 3D shapes
The volume of any 2-dimensional object is always zero (0).but if it is not a 2d then it is a 3d and the volume of that would be bxh divided by3.
8d-3d =65 plus work
3d + 14 = 11 is the equation.
No. 1a and 3d are linear, but 2bc is not. ■
1.6-d=12.8+3d 12.8-1.6=-d-3d 11.2=-4d 11.2/-4=d d=-2.8
So you basically have, (27D-9)+3D = 29+(27D+1) 30D-9 = 27D+30 3D = 39 D = 13
5d+3d = 15 8d = 15 d = 15/8 = 1.875
c = 6 and d = 7
84
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
D + 3D = 240 4D = 240 Divide both sides of the equation by 4: D = 60
84
Add 8 to both sides. 21 - 3d = 0 Add 3d to both sides. 21 = 3d Divide both sides by 3. 7 = d Plug 7 into the original. 13 - 21 = -8 It checks.
