Vincent has already finished 5 oil changes today, and can complete more at a rate of 1 oil change per hour. Warren just came on
IrinaVladis [17]

Answer:

Oil changes = 5

Vincent = 10 oil changes

Warren = 10 oil changes

Step-by-step explanation:

Vincent = 5 + h

Warren = 2h

Where,

h = number of oil changes

How long will that take?

Vincent = Warren

5 + h = 2h

5 = 2h - h

5 = h

h = 5

Number of oil changes = 5

How many oil changes will Vincent and Warren each have done?

Vincent = 5 + h

= 5 + 5

= 10 oil changes

Warren = 2h

= 2(5)

= 10 oil changes

Help please i suck at geometry
Tems11 [23]

Answer:

A

Step-by-step explanation:

10 and 8 are equal

11 and 15 are equal

due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees

180-42=138 degrees

and this means that angle 8 will also be 138 because of what we established earlier
