The density of a certain material is such that it weighs 2 kilograms per quart of volume. Express this density in grams per pint.
*Note: you must use these exact conversion factors to get this question right.
Weight / mass
Volume
1 pound (lb) = 16 ounces (oz)
1 cup (cup) = 8 fluid ounces (fl oz)
i ton (ton) = 2000 pounds (lb)

1 pint (pt) = 2 cups (cups)
1 gram (g) = 1000 milligrams (mg)
1 quart (qt) = 2 pints (pt)
1 kilogram (kg) = 1000 grams (g)
1 gallon (gal) = 4 quarts (at)
1 ounce (oz) = 28.35 grams (g)
1 cubic foot (ft) = 7.481 gallons (gal)
1 pound (lb) = 0.454 kilograms (kg) 1 liter (L) = 1000 milliliters (ml)
1 cubic meter (mº) = 1000 liters (L)
1 gallon (gal) = 3.785 liters (L)
1 fluid Ounce (fl oz) = 29-574 milliliters (mL)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

step-by-step explanation:

sdfghjkl; vbnm,

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
