Solve for u.
- 4(w + 1) = -24

w = 5

Step-by-step explanation:  I think you mean solve for w

1. distribute = -4w -4 = -24

2. add 4 from each side = -4w = -20

3. divide -4 from each side and you should get w = 5

you can plug it in to make sure it is right:

-4(5+1) = -24   ->   -4(6) = -24   ->    -24 = -24

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.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
