Answer:
√50
Step-by-step explanation:
Use Pythagorean Theorem: a^2+b^2=c^2
5^2+5^2=c^2
25+25=c^2
50=c^2
c=√50
Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
