Question

1. Perform the indicated operation. 19-17 divided (6)(6) -36
2. Divide -12 / 0
3. Divide 90 / 18
4. Divide -15 / -3
5. Find the reciprocal of 1/3 (9-4)
6. Subtract - 6.9 - (-7.7)
7. Add 3.03 + (-2.05)
8. Add -3/5 +(8/35)
9. Add 1/8 +1/7

Answer 1

-23 -(-23)/-12 - (-17)
-23 +23)/-12 +17
-23 -(1 & 11/12) +17
-6 -1 -11/12
-5 -11/12

ANS: -4 & 1/12

1, infinity
2, infinity
3, 5
4, 5
5, reciprocal of 1/3 = 3/1 (what is the (9-4) for???)
6, 14.6
7, 0.98
8, -(13/35)
9, 15/56

Answer 2

a) -23 -(-23)/-12 - (-17) = (-23+23) / (-12+17) = 0/5 = 0

1) 19-17 divided (6)(6) -36 = 19 - 17/6*6 - 36 = 19 - 17 - 36 = -34

2) -12/0 = undefined

3) 90/18 = 10/2 = 5

4) -15/-3 = 15/3 = 5

5) 1/3 (9-4) = 1/3(5) = 5/3
reciprocal = 3/5

6) -6.9 - (-7.7) = -6.9 + 7.7 = .8

7) 3.03 + (-2.05) = 3.03 - 2.05 = .98

8) -3/5 +(8/35) = -21/35 + 8/35 = -13/35

9) 1/8+1/7 = 7/56 + 8/56 = 15/56

Answer 3

9. LCM(8,7) = 56
1/8 +1/7 = 7/56 + 8/56
= 15/56

8. LCM(5,35) = 35
-3/5 +(8/35) = -21/35 + 8/35
= -13/35

7. 3.03 + (-2.05) = 3.03 - 2.05
= 0.98

6. -6.9 - (-7.7) = -6.9 + 7.7
= 7.7 - 6.9
= 0.8

5. (1/3)(9-4) = (1/3)5
= 5/3

Reciprocal of 5/3 * 5/3 = 1
Reciprocal of 5/3 = 3/5

4. (-15)/(-3) = 15/3 = 5

3. Find prime factors of 90 and 18
90 = 2*3*3*5
18 = 2*3*3
90/18 = (2*3*3*5)/(2*3*3)
= 5

2. -12/0 is undefined

Answer 4

-- 23 -- ( -- 23) / (--12) -- ( --17)
= --23 + 23/12 + 17
= -- 23*11/12 + 12*17/12
= (--253 + 204 )/12
= -- 49/12

Answer 5

this is to easy, you need to do it yourself, but i will tell you that you cannot divide by zero.
