Answer:

(5,20)

Step-by-step explanation:

Because 3x+2(4x)=55 is then 11x=55, then divide the both by 11 to get x=5

The substitute y=4(5) because of x the get y=20

(5,20)

3x + 2(4x) = 55
3x + 8x = 55
11x = 55 / 11
x = 5

4(5) = 20
y = 20

In a research laboratory, a scientist measures the mass of a 1-carat diamond and finds it to be 200 milligrams, measured to the
vlada-n [284]

Answer:

D=3.5\ gr/cm^3

Step-by-step explanation:

<u>Density</u>

The density of an object of mass m and volume V is given by

\displaystyle D=\frac{m}{V}

It can be expressed in common units like gr/lt, Kg/m^3, gr/cm^3 or any other combination of proper mass [M] by volume [V] units.

The data provided in the question is

m=200\ mg = 0.2\ gr

V=0.057\ cm^3

Thus, the measured density is

\displaystyle D=\frac{0.2\ gr}{0.057 \ cm^3}

\boxed{D=3.5\ gr/cm^3}

We have expressed the result with 1 decimal place because the mass was measured to the nearest hundred milligrams (or one-tenth grams). Any further decimal is senseless because that precision comes from calculations, not from measurements.

A line that is not parallel nor perpendicular to y=2/4x+1
DENIUS [597]

Answer:

y=2x+1

Step-by-step explanation:

Parallel = gradients are the same

Example: y=2/4x+5

Perpendicular = gradients are the inverse of each other

Example: y= -4/2x+1

Any equation would be correct unless the gradient is 2/4 or -4/2
