"If you get the correct answer I will add 10 points to your lowest assignment next week." that's what she said in the email

Answer 1

I think it might be 38
The first equation-
21/3=7
So spider=7
The second-
(17-7)/2=10/2=5
So hat=5
The third-
(11-5)/2=6/2=3
So bat=3
The fourth-
3+5x7=3+35=38

Answer 2

Answer:

7 = spider      5 = hat    3 = bat  missing answer in brackets to use orange pen! 3(7)= 21      7+ (5)(5)=17     5 +(3)(3) =11    3+7+5 = (15)
