PLEASE HELP !!!!!!!!Solve the system of equations using the linear combination method.
vfiekz [6]

Answer:

The solution would be (5, -2)

Step-by-step explanation:

To use this method, start by multiplying the second equation by -1. Then add the two equations together.

9x + 5y = 35

-2x - 5y = 0

------------------

7x = 35

x = 5

Now that we have the value of x, use it to solve either equation for y.

2x + 5y = 0

2(5) + 5y = 0

10 + 5y = 0

5y = -10

y = -2

A scale on a blueprint drawing of a house shows that 10 centimeters represents 2 meters. What number of actual meters are repres
nata0808 [166]

Answer:

<u>3.6 meters</u> are represented by 18 centimeters on the blueprint.

Step-by-step explanation:

Given:

A scale on a blueprint drawing of a house shows that 10 centimeters represents 2 meters.

Now, to find the actual meters represented by 18 centimeters.

Let the actual meters represented by 18 centimeters be x.

As, given the scale on a blueprint drawing of a house shows that 10 centimeters represents 2 meters.

So, 10 centimeters equivalent to 2 meters.

Thus, 18 centimeters equivalent to x.

Now, to solve by using cross multiplication method:

\frac{10}{2}=\frac{18}{x}

<em>By cross multiplying we get:</em>

10x=36

<em>Dividing both sides by 10 we get:</em>

x=3.6\ meters.

Therefore, 3.6 meters are represented by 18 centimeters on the blueprint.
