Let "x" be the scaling factor
3x mums
2x dads
mums appt. + dads appt = total appointments
3x + 2x = 500
5x = 500
x = 100
300 appointments with mums
200 appointments with dads
A^2 + b^2 = c^2....and c is the hypotenuse
5^2 + b^2 = 13^2
25 + b^2 = 169
b^2 = 169 - 25
b^2 = 144
b = sqrt 144...if u take sqrt of both sides, it eliminates the ^2
b = 12....so the other leg is 12 cm.

Answer: 
note: replace 'j' with any other letter you want, assuming your book does not use this letter.
=============================================
Explanation:
j = jenny's score
t = Terrance's score
(4/5)*t = 4/5 of Terrance's score
(4/5)*t+5 = 5 points greater than 4/5 of Terrance's score
represents the inequality connecting Jenny's score and Terrance's score. Saying "her score is no less than some amount" is basically saying "the lowest her score can go is that amount". A specific example: if we say "her score is no less than 12" then this means "her score is 12 or more" and we can write
