Well, first you must find the total amount of tiles that Augustin needs to paint.
So, 300 from the bathroom
675 from the kitchen
+ 100 from the hallway
--------------------
All together, 300+675+100=1075.
Because each can covers 450 tiles, and you are trying to find how many cans you Augustin needs, you woud divide 1075 by 450.
1075/450 is 2.38888888 is not a full number, and you can not have part of a can. You also would not round downward, because then you wouldn't paint all the tiles. Therefore, you would round upward to 3.
Augustin will need 3 cans of paint.
2.85 = 2 17/20 - hope it helps!
Answer:
40 units
Step-by-step explanation:
Given:
Perimeter of ∆ABC = 85 units
AC = 4z
AB = 3z + 3
BC = z + 2
Required:
Numerical value of AC
SOLUTION:
Perimeter of ∆ = sum of all its sides
Perimeter of ∆ABC = AC + AB + BC
85 = 4z + (3z + 3) + (z + 2)
Use this equation to find the value of the variable, z
Collect like terms
Subtract 5 from both sides
Divide both sides by 8
AC = 4z
Plug in the value of x
AC = 4(10)
AC = 40 units
The answer is b A has a greater cost per ride by 10
