Answer:
x = 12
Step-by-step explanation:
Proportional relationship means that 
= k(a constant)
Here, k = 12/8 = 3/2
So, the equation is = 3/2.
Plug in y = 18, and we get 18/x = 3/2.
18 = 3/2x
x = 12
Answer:
x>-15
Step-by-step explanation:
if:x+19>4
collect like terms
therefore:
x>4-19
(sign changes when collecting like terms)
+4-19=-15
x>-15
Answer:
RIGHT ANGLES
Step-by-step explanation:
There are two types of special right triangles, based on their angle measures. The first is an isosceles right triangle. Here, the legs are congruent and, by the Base Angles Theorem, the base angles will also be congruent. Therefore, the angle measures will be 90∘,45∘, and 45∘. You will also hear an isosceles right triangle called a 45-45-90 triangle. Because the three angles are always the same, all isosceles right triangles are similar.
