What is a possible result of simplifying the equation 15x - 4 = 3(5x-4)?

1 answer:

4 0

They equal different things. If you simplify the second equation, it is 15x-4 = 15x-12 because of the 3 outside of the paranthesis. Therefore, the equation is wrong.

3. Each bangle printed by a 3D printer has a mass of exactly 25 g of metal. If the density of the metal is 14 g/cm3, what length

nadezda [96]

Answer:

57.0 cm

Step-by-step explanation:

We know that the radius of the filament is 1 mm. Taken to cm, is 0.1 cm.

From the density and mass, we can get the volumen of the bangle:

d = m/V ----> V = m/d

Solving for V:

V = 25 / 14 = 1.79 cm^3

We can assume that a bangle is a cylinder so:

V = π*r^2*h

1.79 = 3.14 * 0.1^2 * h

h = 1.79 / 3.14 * 0.01

h = 57.0 cm

Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?

kolbaska11 [484]

Answer:

See Explanation

Step-by-step explanation:

Given

$Allen = \frac{3}{4}hr$ less than the most hour

Required

Hours read by Miss Allen

The question is incomplete, as the hours read by each student is not given.

To solve this, I will assume that the longest hours read by a student is x.

So, the expression for Miss Allen will be:

$Allen = x - \frac{3}{4}hr$

Assume that $x = 1hr$

The expression becomes

$Allen = 1hr - \frac{3}{4}hr$

Take LCM and solve

$Allen =\frac{4 - 3}{4}hr$

$Allen =\frac{1}{4}hr$
