Obviously, there is 784/7, but there is a less common kind of expression that also works. Since a fraction is similar to a division expression, you can flip 7 to make 1/7. The other expression could be 1/7 x 784.
So the two expressions could be 784/7 and 1/7 x 784

The pair of triangles that can be <span>proved congruent by SSS theorem would be the triangles where the corresponding sides of each triangle being equal. From the images attached,

I think the correct answer would be the triangles in F.</span>
Answer:
Let x = the number of adult tickets sold
Let x + 61 = the number of student tickets sold
x + x + 61 = 761
2x = 700
x = 350
x + 61 = 411
If it's a right triangle, and is also an isosceles triangle, namely two sides are of equal length, that means the other non-right-angles are 45° each, so the triangle is a 45-45-90 triangle, and thus we can apply the 45-45-90 rule, so let's do so. Check the picture below.
