Lucia has 3.5 hours left in her workday as a car mechanic. Lucia needs 1/2 of an hour to complete one oil change.
MatroZZZ [7]

Answer: So Lucía has 3.5 hours left, and need 1/2 of an hour (or 0.5 hours) to do one oil change.

a) If you divide the total time she has by the time she needs for each oil change, then you got the total number of oil changes that she can do in that time; this is:

3.5/0.5 = 7

So she can do 7 oil changes in 3.5 hours.

b) If she can complete two car inspections in the same amount of time it takes her to complete one oil change, then she can do two car inspections in 0.5 hours.

2*car inspections = 0.5 hours

car inspection = (0.5/2) hours

then one car inspection will take 0.5/2 = 0.25 hours.

c) Two ways to solve this:

1) Do the same that we did in a), this is: 3.5/0.25 = 14

she can do 14 car inspections.

2) If in 3.5 hours, she can do 7 oil changes, and in the time she does an oil change, she can do two car inspections, then in 3.5 hours she can do 7*2 car inspections, and 7*2 = 14

Will give Brainliest. Write a linear equation for this statement:
Llana [10]

Answer:

H(d) = -9.5(d-1) + 100

Step-by-step explanation:

Let d_n denote the number of hits on day n, then:

d_1 = 100, d_3 = 81

we can calculate that over the 2 days, the number of hits decreased by 19.

Assuming this is a linear equation and not an exponential decay line, then the series equation would be: d_n_+_1 = d_n - 9.5

To write this as a linear equation, if H(d) is a function where d is the day starting from 1 and H(d) is the nubmer of hits on that day:

H(d) = -9.5(d-1) + 100
