Question

−1/2x+1/3>3/5

1. x<-8/15
2. x<-4/15
3. x<8/15
4. x<4/15
5. x>-8/15
6. x>-4/15
7. x>8/15
8. x>4/15

Answer 1

Explanation:

(7/8 - 4/5)^2 = 9

1600

= 0.005625

Calculation steps

Subtract: 7

8

- 4

5

= 7 · 5

8 · 5

- 4 · 8

5 · 8

= 35

40

- 32

40

= 35 - 32

40

= 3

40

The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40

Power: 3

40

^ 2 = 32

402

= 9

1600

hopefully it's right
