Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x A) -32/9 B) -9/32 C) 32/9 D) 9/32

Greeley [361]

Option C

$x = \frac{32}{9}$

Solution:

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

We have to solve for "x"

From given,

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

$x - 4 + \frac{x}{2} = x + 12 - 3x - x$

Combine the constants

$x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16$

Move the variables to left side of equation

$x + \frac{x}{2} + 3x = 16$

Combine the like terms

$2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}$

Thus option C is correct

Juan's living room floor is shaped as shown. He wants to buy a rug the covers at least half of the floor area. Answer yes or no

slega [8]

Answer:

Step-by-step explanation:

Find the area of the shape by creating two shapes. A large rectangle and a very small triangle. The area of the rectangle is 13x12, and the area of the triangle is (1/2)3x4. The area of both shapes together is 6+156=162.

Now you can easily calculate the area of each rug and determine whether it is over half of 162 (because 162 is the area of the entire floor), or under half of 162. If it is under 81, then it does not cover at least half of the floor.

12x6 = 72 no

10x9 =90 yes

13x12 = 156 yes

3x12 = 36 no

8x8 = 64 no
