We can represent 8 with eight unit blocks. Also, we can represent 0.2 with two tenth blocks. So we have

8*(unit blocks) + 2*(tenth blocks) = 8*1 + 2*(0.1) = 8 + 0.2 = 8.2

The two triangles on the side are 18 in^2 and the square in the middle is 36 in^2. So in total, it has an area of 72 in^2

Answer:

(6x+3)=120

6x=120-3

6x=117

x=117/6

x=19.5

(7x-19)=120

7x=120+19

7x=139

x=139/7

x=19.85

Pls answer the question with explanation

Answer:

a) She started walking back

b) 0.13 km/min

Step-by-step explanation:

The graph shows the distance traveled by Jo. She starts her journey (t=0) at a distance of 0 Km since the graph passes through the origin (0,0).

a) Ten minutes later she is at a distance of 1 km from the starting point and then the distance starts to drop. This means that at t=10 minutes, she started walking back.

b) To calculate the speed for the last 30 minutes of journey, we find the slope of the line. Select the points (30,0) and (60,4).

If a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Substituting:

$\displaystyle v=\frac{4-0}{60-30}=\frac{4}{30}$

v=0.13 km/min
