Use the algebraic expressions for the length and width of Marlene's living room found in the
krok68 [10]

Answer:

<em>The area of Marlien's living room is 420 square ft</em>

Step-by-step explanation:

Before calculating the real dimensions of Marlien's living room, we must find the value of x.

Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.

The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:

2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2

Simplifying:

-10 + x - 2 = 2

x = 10 + 2 + 2

x = 14

Since x=14 feet, the dimensions of Marlien's living room are

width=x=14 feet

length=2x+2=30 feet

Thus the area is:

A = 14*30 = 420 square ft

The area of Marlien's living room is 420 square ft

In a survey of 120 8th graders, 84 liked math, 73 liked science and 23 liked math but not science. how many students disliked bo
hammer [34]
24  
We can divide the 8th graders into 4 groups. They are: 
1. Like both math and science. 
2. Like only math. 
3. Like only science. 
4. Don't like either math or science.  
The sum of the people in all 4 groups will add up to 120. So let's see how many are in each group. 
We've been given 23 as the number of people who like only math (group 2).
And since we know that 84 people like math, that means that 84 - 23 = 61 people are in group 1. And since we know that 73 people like science, that means that 73 - 61 = 12 are in group 3. So of the 4 groups, we now know. 
1. Like both math and science (61 people).
 2. Like only math (23 people).
 3. Like only science (12 people).
 4. Don't like either math or science (unknown).
 
 So for the people left in group 4 (don't like either subject) that will be 120 - 61 - 23 - 12 = 24.
