To answer this item, we may divide the given figure into two: (1) upper portion and (2) lower portion.

We solve first for the area of the lower portion figure, that is a rectangle with height equal to 1 unit and length of 5 units. 

The area of a rectangle is calculated by multiplying its dimensions as shown in the formula below.
                        Area = Height x Length
Substituting,
                       Area = (1 unit) x (5 units) = 5 unit squared

Next, we have the second figure, upper portion. The length of this figure is given to be 2 units. The height is equal to 5 units - 1 unit because the 1 unit was already covered in the first figure. Thus, the height is equal to 4 units.

Solving for the area,
                       Area = (4 units)(2 units) = 8 units squared

Then, adding up both areas,
                 total area = (5 unit squared) + (8 unit squared) = 13 units squared

<em>ANSWER: 13 unit squared</em>

The answer is $8 per hour. To get this you add the 2 1/2 and 4 1/4 and that equals 6 3/4 or 6.75. You then divide 54 by 6.75 and you get 8.

X + 2y = 10<br> 3x + 4y = 8<br><br> Which point is the solution to the system of equations?
bija089 [108]

Answer:

x = -12

y = 11

Step-by-step explanation:

i used substitution and let 'x' = 10 - 2y

3(10 - 2y) + 4y = 8

30 - 6y + 4y = 8

30 -2y = 8

-2y = -22

y = 11

x + 2(11) = 10

x + 22 = 10

x = -12
