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.

1/3y+11=1/2y-3<br><br> What is y???
olga55 [171]

Answer:

y=84

Step-by-step explanation:

\left(\frac{1}{3}\right)y+11=\left(\frac{1}{2}\right)y-3

Use distributive property.

\frac{1}{3}y+11=\frac{1}{2}y-3

\frac{1}{3}y+11-11=\frac{1}{2}y-3-11

\frac{1}{3}y=\frac{1}{2}y-14

\frac{1}{3}y-\frac{1}{2}y=\frac{1}{2}y-14-\frac{1}{2}y

-\frac{1}{6}y=-14

\left(-\frac{1}{6}y\right)\left(-6\right)=\left(-14\right)\left(-6\right)

y=84
