Liz is using the distributive property to evaluate the expression 27(36) by using friendlier numbers. Her work is shown below.

Katen [24]

Liz attempted to factor 36. Since 36 = 3*12 and not 3+12, this is not the way to go. In stead of factoring 36, she should have split it into a friendly sum, like 36=30+6.

Then Step 1 should have been 27(6+30).

PLEASE HELP ME ...........Julie was looking at the architect's blueprint of her house. The scale on blueprint was 1/4 inch = 1 f

MAVERICK [17]

Answer:

On the blueprint the dimensions are 48 inches by 64 inches.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be $x$ by $y.$

As, given the scale on blueprint:

$\frac{1}{4}\ inch=1\ foot$

So, $\frac{1}{4}\ inch$ is equivalent to 1 foot.

Thus, $x$ is equivalent to 12 feet.

And, $y$ is equivalent to 16 feet.

Now, solving by cross multiplication method:

$\frac{\frac{1}{4}}{1} = \frac{x}{12}$

$\frac{4}{1} =\frac{x}{12}$

By cross multiplying we get:

$48=x$

$x=48\ inches.$

Now, again:

$\frac{\frac{1}{4}}{1} =\frac{y}{16}$

$\frac{4}{1} =\frac{y}{16}$

By cross multiplying we get:

$64=y$

$y=64\ inches.$

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.
