Answer:
x +0y+0z = 400
-x +y+0z = 150
-8x +0y +z = 250
Step-by-step explanation:
The last column is the solution
The rest of the columns are the coefficients of the variables
x +0y+0z = 400
-x +y+0z = 150
-8x +0y +z = 250

I think that you round to 9.80 seconds. Pardon me, I didn't understand the problem well
Each square in the diagram is equal to the value of 1 while c isn't equal to the squares. Simply 
. Since there are 6 squares that means 1*6 = 6. The whole value of the squares is 6. While the rectangle value isn't known or defined as "c" and you have 3 rectangles the value of it would be 3*c which is 3c.
So the answer is <u>C. 6+3c</u>
Answer:
the tree is 8.8 m tall
I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.
Step-by-step explanation:
it's a proportional relationship
5/22=2/height
5(height)=2(22)
5(height)=44
divide both sides by 5
5(height)/5=44/5
height=8.8 m
