68 containers because 8.5 * 8 is 68
Answer:
Step-by-step explanation:
find the area of every face and the base
area of face 1= 2
area of face 2= 2
area of face 3 = 2
area of base 1= 1.7
7.7 in squared
area of a triangle is the base x height divided by 2
face 1- 2 x 2=4
4/2=2
2x3(theres 3 faces to a triangle) =6
area of base- 2 x 1.7= 3.4
3.2/2=1.7
add the faces and the base together
7.7
Answer:
Step-by-step explanation:
Let's use the addition/elimination method to solve this. If we multiply the first equation through by -1 we can eliminate the x terms. Doing that gives us:
-x + 3y = 3
x + 3y = 9
The x's subtract each other away leaving us with
6y = 12 so
y = 2.
Now we will plug in 2 for y in either of the original equations to solve for x:
x + 3(2) = 9 and
x + 6 = 9 so
x = 3
The coordinate for the solution is (3, 2) or x = 3, y = 2
The second choice down is the one you want.
27 liters of paint... 3 liters per jug a total of 9 jugs meaning 9x3=27
