Question

Can someone help me with these?

Answer 1

#1 is 14

Explanation:

if a = 16, and you're doing a - 4, that means 16-4, which is 14 :)

Answer 2

1.) 16-4=12
2.)2(3)+9=15
3.)26/2=13
4.)5(9+3)-6=54
5.)6^2+23=59
6.) 3(8)-11=13
7.) (5-2)•9=27
8.) 2(3^2)•5=90
9.) 22,20,18
10.) W=2,3,4~ 3v+w= 14,21,28
11.) y=1,2,4~ x^2+y = 4, 18, 16
