Rasek [7]3 years ago

Answer:

Infinite Solutions/Many solutions

Step-by-step explanation:

Use PEMDAS.  P=parenthesis.  5(x-x).  x-x=0, and 0 multiplied by any number is ALWAYS zero.

2x+2x is 4x

Since 4x=4x no matter what x is, there is an infinite set of solutions

How to solve the problem 3.2d-4d=2.3d+3
Liula [17]
3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97

or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97

A cuboid made of metal has dimensions 10 cm, 8 cm and 5 cm. The mass of the cuboid is 1.1 kg.
nalin [4]

Answer:

0.00275 \frac{kg}{cm^{3} }

Step-by-step explanation:

Density is D = M/V, where D = density, M = mass, and V = volume.

  1. First, I would calculate the volume. For the volume, you will multiply all the values you are given along with their units. 10cm  *  8cm * 5cm = 400cm^{3}
  2. You would then plug the values you know into D = M/V. Your mass is 1.1kg, so D = 1.1 kg / V
  3. Your volume is 400 cm^3, so D = 1.1kg/400 cm^3
  4. Keeping the units, you would divide to get a density of 0.00275 kg/cm^3

Hope this helped!
