Samuel is running a 3-mile race. He would like to finish the race in under 33 minutes. He has already run for 10.5 minutes. The

Y_Kistochka [10]

For this case we have the following inequality:
$10.5 + x \ \textless \ 33
$
From here, we define the variable x.
x: number of minutes remaining to finish the race.
From here, we clear the value of x.
We have then:
$x \ \textless \ 33-10.5
$
$x \ \textless \ 22.5
$
Therefore, Samuel has less than 22.5 minutes to finish the race in the estimated time.
Answer:
x < 22.5; Sam has fewer than 22.5 minutes left to finish running.

Eight times the reciprocal<br> of a number equals 4 times<br> the reciprocal of 10.

saveliy_v [14]

Answer:

8(1/x) = 4(1/10)

Step-by-step explanation:

lets say the number is x

eight times the reciprocal of a number equals 4 times the reciprocal of 10

8 * 1//x = 4 * 1/10

8/x = 4/10 , cross multiply

4x =8*10, divide both sides by 4

x= 80/4

x= 20
