Write a compound inequality to represent all of the numbers between -4 and 6.

Step-by-step explanation:

We have to form a compound inequality to represent all of the numbers between -4 and 6.

Let x represent all the numbers lying between -4 and 6.

It is clear that x will always be greater than or equal to -4

Also, x will always be less than or equal to than 6

Combining the two inequalities will give us the required compound inequality.

d

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
