Is it true or false you get (2,12) after you solve 3x-1/2y=0?

1 answer:

5 0

It's true that (2, 12) is a solution of 3x-1/2 y = 0 .

It's also true that (1, 6), (3, 18), (5, 30), (9, 54), (150, 900),
and (12 million, 72 million) are also perfectly correct solutions.

Any pair of numbers where the 'y' number is six times as much as
the 'x' number is a solution to that equation.

There are an infinite number of them.

If a parking lot holds 1,600 cars and fills 3/4 of its spaces, how many spaces are filled?

AnnyKZ [126]

The total space in the parking lot is 1600 cars

It is mentioned that $\frac{3}{4}$ parts of this parking is filled

Now we are required to find what is the three-fourths part of 1600

To find it we multiply $\frac{3}{4}$ times 1600

$\frac{3}{4} X 1600$

= $\frac{3X1600}{4}$

= $\frac{4800}{4}$

= 1200 cars

Hence 1200 cars fills the three-fourths of the car parking lot that has a capacity of 1600 cars

A system of equations is given below:

My name is Ann [436]

Solving by substitution:

y = 4x - 3

2x + 7y = 41

Let us substitute the first equation y = 4x - 3 into the second.

2x + 7y = 41

2x + 7(y = 4x -3) = 41

2x + 7(4x -3) = 41

So that's the third option.

I hope this helps.
