Of the 20 sandwiches prepared by Ali, Ben and Carla, Ali made a total of A) two sandwiches
Information of the problem:
- Total of sandwiches: 20
- Ali = x
- Ben = 3x
- Carla = 2*(3x)
To solve this problem we have to state the equation using the information of the problem:
Total of sandwiches = Ali + Ben + Carla
20 = x + 3x + 2*(3x)
20 = x + 3x + 6x
20 = 10x
x = 20 / 10
x = 2
Substituting the (x) value into the information of the problem we get:
Ali = 2 sandwiches
Ben = 3*2 = 6 sandwiches
Carla = 2*(3*2) = 2*6 = 12 sandwiches

Answer:
ASA congruence theorem
Step-by-step explanation:
WE know by given that <em>∠S ≅∠U</em> and<em> line ST ≅ line UT</em>
By the vertical angles theorem, we can find that ∠RTS ≅ ∠VTU.
They are in a form that when looking around the edge, you see congruent <em>angle, side, then angle</em>. That means that we can prove the triangles' congruence with ASA congruence.

Answer: x = -1
Step-by-step explanation:
i assume you mean
5x-(5x+3) = -1/3(12x+21)
lets start with the left
-(5x+3) can be turnd into -5x-3
now it is
5x-5x-3 and that can be just -3
now lets go to the right and get rid of the 1/3
we see the 3 at the bottom of 1/3, and (12x+21) can be factored with 3
so 1/3 x 3(4x+7) is what we get
1/3 x 3 cancels out so we are left with
-3 = (-4x-7)
lets try to get -4x by itself
if you move -4x to the left, turning it into 4x, and move -3 to the right, turning it into 3, you get 4x = -7 +3
-7 +3 = -4
4x = -4
devide by 4
4x/4 = -4/4
x = -1
