Solve the equation 3(x+4.5)=36. If you get stuck, use the diagram.

Stells [14]

Answer:

x=7.5

Step-by-step explanation:

Let's solve your equation step-by-step.

3(x+4.5)=36

Step 1: Simplify both sides of the equation.

3(x+4.5)=36

(3)(x)+(3)(4.5)=36(Distribute)

3x+13.5=36

Step 2: Subtract 13.5 from both sides.

3x+13.5−13.5=36−13.5

3x=22.5

Step 3: Divide both sides by 3.

3x/3=22.5/3

x=7.5

Answer:

x=7.5

Frank got a gift for his sister and put it in a shoebox.

Leona [35]

Answer:

The correct answer is option C.

Step-by-step explanation:

Length of shoe box = l = 11 inches

Width of the shoes box = w = 6 inches

Height of the shoe box = h = 5 inches

Wrapping paper required t cover the shoe box will be equal to the total surface area of the shoe box.

Shoe box = Cuboid

Total surface area of the cuboid = 2(lw+wh+hl)

Total surface area of shoe box : T

$T=2\times (11 inch\times 6 inch+6 inch\times 5 inch+5 inch\times 11 inch)$

$=T = 302 inch^2$

Frank will need 302 square inches of wrapping paper to cover the shoe box.
