Answer:
A number line from negative 10 to 10 is shown, with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 8. Another arrow points from negative 8 to negative 6
Step-by-step explanation:
A number line is a straight line with numbers placed at equal intervals. Positive numbers are placed to the right of 0 and negative numbers are placed to the left of zero.
When a number (x) is added x unit is moved to the right while if a number (x) is subtracted x units is moved to the left.
To solve -8 - (-2) = -8 + 2
Given a A number line from negative 10 to 10 with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 8 then since 2 is added, we move 2 units right from negative 8 to negative 6.
Y=(11/8)x+6
subtract the 8y to the right then add the 48 to the left then divide by 8
So the train is pulling about 50 cars in total, and there's about 30 boxes of freight in each car.
30 x 50 = 1500
The best estimate would be near 1500 boxes of freight through the whole train.

Answer:
The area of the figure is 86.13
Step-by-step explanation:
First, solve for the area in the triangle using the equation A = h*b/2
We have the height and the base which is 6. Plug in for the equation and solve.
A = 6*6/2
A = 36/2
A = 18
Next, solve the area for the rectangle using the equation A = w*l
The width is 6 and the length is 9. Plug in for the equation and solve.
A = 6*9
A = 54
And finally, solve for the area of the triangle using the equation A = pi*r^2
We know that pi is around 3.14 and the diameter is 6. We know that a diameter is twice the length of the radius, so we can divide the diameter by 2 and get the radius.
r = 6/2
r = 3
Now plug in the equation and solve.
A = 3.14*3^2
A = 3.14*9
A = 28.26
Since this is the area of a full circle, we need to divide the area of it by 2 to get the area of a half circle.
A = 28.26/2
A = 14.13
Next, add them all up and you will get your answer.
18 + 54 + 14.13 = 86.13
Hope this helps.
