What is the value of y for the linear equation, <br> x + x = 2x - 4y +16
fomenos
Isolate the variable by dividing each side by factors that do not contain the variable.
2x=2x-4y+16
2x-16=2x-4y
-4y would have to equal -16
Therefore Y=4

Orbital Toys sells two types of sets of magnetic spheres, silver and brass. The store owner, Lucy Ball, pays $8 and $16 for each
sdas [7]

Answer:

The maximum profit will be reached by buying 500 brass magnetic spheres and 1500 silver magnetic spheres.

Step-by-step explanation:

In order to solve this you need to create a system of equations, with two values that will create the answer we are looking for, the thing that we don't know here is how many of each are we buying so the number of silver magnetic spheres will be represented by "y" and the brass magnetic spheres will be represented by "x".

So we know that x+y=2000

That's our first equation, our second would be the expense, which would be

8x+16y=20,000

We now just solve for one of them

x=(2000-y)

8(2000-y)+16y=20,000

16,000-8y+16y=20,000

8y=4,000

y=500

So we know that the maximum profit will be reached by buying 500 brass magnetic spheres and 1500 silver magnetic spheres.

Which of the following is not approximately equivalent to one of the metric units: 1 kilometer, 1 meter, 1 kilogram, or 1 liter?
Nikitich [7]
A.
Note that 1 mile = 1.609 km.
Therefore
0.6 miles = 0.6*1.609 km = 1 km (approximately).

b.
Note that 1 US quart = 0.9463 liters.
Therefore
1 quart = 1 liter (approximately).

c.
Note that 1 pound = 0.4536 kg
Therefore 1 pound is not even approximately equal to one kilogram.

d.
Note that 1 yard = 0.9144 m.
Therefore
1 yard = 1 m (approximately).

Answer:
1 pound is not approximately equivalent to one of the metric units.
