Answer:
1) (b) Zero
2) (d) 170°
3) No
4) z = 4
5) y = 7
6) x= 3
7) -7/5
8) 1011/100
9) 35/20 > 15/20
10) a positive number.
Step-by-step explanation:
1)Sum of a rational number and its additive inverse is zero. For example, 1/2 is a rational number whereas -1/2 is its additive inverse. so, their sum is zero (0)
2) *in the attachment*
3) 8/9 is not the multiplicative inverse of -1/18 because when we multiple 8/9 and -1/18, we won't get 1 as the answer
4) *in the attachment*
5) *in the attachment*
6) *in the attachment*
7) reciprocal of -5/7 is -7/5
8) *in the attachment*
9) 15/20 = 0.75 whereas 35/20 = 1.75, and 1.75 is greater than 0.75, therefore 35/20 > 15/20
10) the reciprocal of a positive number is always a positive number.
Hope this was helpful!!
Answer:
1) 0
2) 170°
3) the reciprocal of the given rational number is known as it's multiple inverse,so the multiple inverse of 8/9 is -9/8
4)6=z+2
6-2=z
x=4
5)y+3=10
y=10-3
y=7
6)x+3/7=17/7
x=17/7-3/7
x=2
7)7/5
8)1011/100
9)15/20={(15x2)(20x2)}=30/40
35/40={(35x1)(40x1)}=35/40
now 30<35
(30/40)<(35/40)
there fore 35/40 is greater
10) negative (-)
