Answer:

4 1/2 hours.

Question 1 - You need to split the L shape into  2 shapes.

6mm x 2mm = 12mm

and

5mm x 2mm = 10mm

add 12mm and 10mm 
the area is 22mm squared (a little 2 above the mm)

question 2 - you need to do the same

4mm x 2mm = 8mm squared 
7mm x 2mm = 14mm squared
area - 22mm squared

Brooklyn Bridge is 5,985 ft long and 85 ft wide. What distance is one sixth of its length
I am Lyosha [343]

Answer:

The distance is 997.5 ft.

Step-by-step explanation:

Given:

Length of Brooklyn Bridge = 5,985 ft.

Width of Brooklyn Bridge = 85 ft.

We need to find the Distance

Distance = \frac{1}{6}\times lenght

Substituting the value of length to find distance we get;

Distance = \frac{1}{6}\times 5985 = 997.5 ft.

Hence Distance is 997.5 ft.

A. Adding 8x to both sides wouldn't cancel anything out. 
B. Adding 15 to both sides will cancel out 15 making it easier to solve for x.  
C.Adding 3 to both sides will not cancel anything out.

0.4(2x+1/2)=3[0.2x+(-2)]-4 solve the equation
melisa1 [442]
0.4(2x+1/2) = 3[0.2x-2]-4
0.8x+0.2 = 0.6x-6-4         Distribute it out
0.8x+0.2 = 0.6x-10          Combine like terms
0.2x = -10.2                     Subtract 0.6x and 0.2 from both sides
x = -51                             Multiply both sides by 5
