Answer:
Step-by-step explanation:
So here we have a 45-45-90 triangle.
This a special right triangle were the sides across from the 45 degree angles can be considered x, while the hypotenuse is two square roots of x.
Here since we have the sides across from the 45 degree angle we can conclude that 
So if we wanted the hypotenuse we would just plug in this value of x like so:
Therefore the hypotenuse is 18.
Answer:
y=7+3x
Step-by-step explanation:
Since she already has 7 in her account and she ADDS 3 more each day you would multiply 3 by x which represents the number of days and add that to seven because she already had it. This would equal to Y which represents the total in her account

Answer:
x=19
Step-by-step explanation:
50 - 3x = x -26
50-3x-50=x-26-50
-3x=x-76
-3x-x=x-76-x
-4x= -76
x= -76/-4
x=19
