$1. \: = > 4( - 7) \\ = 4 \times - 7 \\ = - 28$

$3. \: = > 9( - 12) \\ = 9 \times - 12 \\ = - 108$

$4. \: = > - 6( - 8.75) \\ = 6 \times 8.75 \\ = 52.5$

$5. = > 27( - 3) \\ = 27 \times - 3 \\ = - 81$

$7. \: = > - 55(0) \\ - 55 \times 0 \\ = 0$

$8. \: = > ( - 7)( - 7.25) \\ = 7 \times 7.25 \\ = 50.75$

$11. \: = > ( - 1) {}^{4} \\ = 1 {}^{4} \\ = 1$

$13. = > 42 \div ( - 7) \\ = - (42 \div 7) \\ = - 6$

$15. = > - 9 \div 3 \\ = - (9 \div 3) \\ = - 3$

An object travels 4/5 mile in a half in hour. What is its speed?

goldfiish [28.3K]

The rate(speed) is 1 3/5

We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr

Substitute

4/5= 1/2t

Multiply 2 on both sides
2* (4/5)=(1/2)t * 2

8/5=t

We can simplify this to 1 3/5
