Answer:
x = 2
Step-by-step explanation:
OK so lets do it together.
2x = -2x + 8
Subtract 8 from both sides
2x - 8 = -2x
Add 2x to both sides
4x - 8 = 0
Add 8 to both sides
4x = 8
Divide each side by 4
x = 2
Check:
4 = -4 + 8
4 = 4
correct

This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio 
so we get
We could have also gotten this using Trig:
Or by recognizing u=v because remaining angle is 45 so this must be isosceles so
Answer:
D
Step-by-step explanation:
Ok well first off the bat, you know that obviously AC is equal to itself since the triangles share a side. That's Reflexive Property just saying. This is your first equal side.
AB is congruent to DC will form the term SSA in order.
AB is congruent to CD will form the term SSA in order.
AD is congruent to DC will form the term SSS or SSA in order.
AD is congruent to BC will form the term ASA in Order.
So AD is congruent to BC is the Answer!

Answer:
t = $23
s= $47
Step-by-step explanation:
First order =
13t + 4s = 487
Second order
6t + 2s = 232
13t + 4s = 487 (1)
6t + 2s = 232 (2)
Multiply (2) by 2
12t + 4s = 464 (2b)
13t + 4s = 487
12t + 4s = 464
Subtract
12t - 10t = 487 - 464
t = $23
Substitute t = 23
13t + 4s = 487
13(23) + 4s = 487
299 + 4s = 487
4s = 487 -299
4s = 188
s = 188 / 4
= 47
s= $47
