Answer: The correct option is (B) 4.

Step-by-step explanation: We are given to find the value of x in the following equation :

$1.5(x+4)-3=4.5(x-2)~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the value of x, we need to solve equation (i) for x.

The solution of equation (i) is s follows :

$1.5(x+4)-3=4.5(x-2)\\\\\Rightarrow 1.5x+6-3=4.5x-9\\\\\Rightarrow 1.5x+3=4.5x-9\\\\\Rightarrow 4.5x-1.5x=3+9\\\\\Rightarrow 3x=12\\\\\Rightarrow x=\dfrac{12}{3}\\\\\Rightarrow x=4.$

Thus, the required value of x is 4.

Option (B) is CORRECT.

1.5(x + 4) - 3 = 3.5(x - 2)

We need to use the distributive property to simplify this.

1.5x + 6 - 3 = 3.5x - 7

Subtract 1.5x from both sides

6 - 3 = 2x - 7

Simplify left side

3 = 2x - 7

Add 7 to both sides

10 = 2x

Divide both sides by 2

x = 5

Answer:

x = 24

Step-by-step explanation:

$\frac{4}{3}$ x + $\frac{1}{6}$ x = 36

Make the denominator the same by multiplying the first fraction by 2 to make both denominators 6.

$\frac{8}{6}$ x + $\frac{1}{6}$ x = 36

Now we can calculate the numerators and keep the denominators the same.

$\frac{9}{6}$ x = 36

Find x.

$\frac{6}{6}$ x = $\frac{6}{9}$ × 36

x = 24

ki77a [65]

Answer:

draw lines center to vertex
43.5 square inches
261 square inches

Step-by-step explanation:

Part A:

The area can be decomposed into triangles by drawing a line from the center to each vertex of the hexagon.

Part B:

The area of each triangle is given by the triangle area formula:

A = (1/2)bh

A = (1/2)(10 in)(8.7 in) = 43.5 in²

Part C:

The area of the table top is 6 times the area of one triangle:

surface area = 6(43.5 in²) = 261 in²
