Answer 1

1)a)305.7-105.27=200.43
b)19.2-17.02+137.34=139.52
a+b=200.43+139.52=339.95

2)107.5-87.557=19.943
19.943+17.85=37.793

3)a)3.125+15+82.3-17.32=83.105
b)13.7-1.05+21.31=24.51
a-b=83.105-24.51=58.595

4)a)24.43-x=8.938⇒
8.938-24.43=x⇒
x=15.492

b)7.28+x=132.57⇒x=132.57-7.28⇒x125.29

c)x-37.5=132.04⇒x=132.04+37.5⇒x=169.54
d)x+4=27.5⇒x=27.5-4⇒x=23.5

5)(1.43)∧102=(1.43)∧x+1
102=x+1⇒102-1=x⇒x=101
