8x + 5y = 22<br> -8x + y = 14
finlep [7]

Answer:

Y = 6 X=-1

Step-by-step explanation:

  1. Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
  2. So that means 6y=36. So Y would equal 6
  3. Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
  4. Minus 22 from both sides.
  5. That would give you 8x=-8
  6. So x would equal - 1

2. An articulated truck is loaded with cylindrical containers filled with oil. The height of each container is 80cm and the diam
RoseWind [281]

The volume of each container is: 25,133 cm^{3}

Given:

height of container (h) = 80 cm

diameter of container (d) = 20 cm

radius = half of diameter = \frac{1}{2} of 20 = 10 cm

Recall:

Volume of a cylinder = \pi r^{2} h

<em>Substitute the values into the formula:</em>

Volume = \pi \times 10^{2} \times 80 = 25132.74123

Therefore, volume of each cylinder is approximately 25,133 cm^{3}
